Description

The invention relates to a radiator having at least two heating elements, at least one flow and at least one return and at least one device for separately controlling the supply of heating medium to the at least two heating elements and a control or valve device for use on a radiator.

Such radiator and control or valve device are known in the art. In particular flat radiators with at least two heating plates can be flowed through the special leadership of the heating medium or in particular heated water, first the front to a living space directed heating plate of the heating medium and only then the second rear heating plate, which is directed away from the living room. All the heating elements or heating plates belonging to the heating element are thereby flowed through by the heating medium in the circuit between the heat source, that is to say a heating boiler, and the heat exchanger, that is to say the heating element.

For example, this describes DE 10 2007 036 141 A1 a flat radiator or a heating wall for a partial load operation, which has a flow connection, a return connection, a first through-flow and the space to be heated facing the heating plate and at least one further flowed through and arranged behind the heating plate. Between the upper and lower end portions of the heating plates connecting pieces are arranged. Further, a radiator valve for controlling the total mass flow of a heating medium is provided, wherein through a selective arrangement of shut-off valves in at least one of the connecting pieces, the first heating plate is flowed through substantially uniformly in front of the other heating plates. In one of the upper connectors another radiator valve is integrated, with which the mass flow of the heating medium is passed into the rear heating plate via an overflow connection. Here, an additional radiator valve is integrated in an upper connector, with the mass flow from the flow through a pipe socket with integrated radiator valve in the inlet opening of the rear plate using a solid obturator and an overflow connection is controlled. Regulation is via a conventional radiator thermostat. The setting of the second rear thermostat is adjusted to the setting of the control element or thermostat for the control of the total mass flow. The second thermostat only opens in the event of a large drop in temperature in a room and thus switches on the rear panel or the rear panels in order to achieve the required heating capacity. As a rule, the additional radiator valve for controlling the mass flow in the rear plate remains closed. The total mass flow supplied via the first valve then flows only into the front plate. Embodiments with equal operability are disclosed, in which the radiator valves are associated with a connecting piece, which is designed as a double piece and is provided internally with a shut-off device. The overflow connection is designed as a U-shaped pipe socket. Alternatively, a mutual operability is disclosed, in which the two radiator valves are assigned to separate connecting pieces, which are formed as normal tees or T-pieces with integrated valve seat. The overflow connection is designed as a pipe connection between the two upper connecting pieces.

The DE 10 2007 036 139 A1 discloses a two- or multi-row radiator, in particular flat radiator with a flow connection and a return connection and a first flowed through and the space to be heated facing portion and another flowed behind arranged section. The first section is flowed through substantially uniformly in front of the remaining sections, at least one connection to the one further section being provided only at the lower end region of the first section. Further, this prior art document discloses that a radiant and a convection heating section may be controlled by a valve device provided with a housing, at least two feeds, or at least two returns, a closure device, each of which Pre-or feeds or each of the return and operations is assigned, is provided.

The present invention is based on the object, a separate control of two or more multi-row radiators, which is simpler than in the prior art and more economical in partial load operation to provide. In particular, a radiator assembly is to be created, which can be so impelled by means of a specially equipped control or valve device or valve set that at full load operation of the entire radiator and in part load operation, only a portion of the radiator or individual heating segments are flowing and heated by the heating medium.

The object is achieved for a radiator according to the preamble of claim 1, characterized in that the device comprises at least one setting or valve means for controlling the supply of heating medium to the first heating element and for controlling the supply of heating medium to the at least one further heating element, wherein the adjusting or valve device is designed so that in the partial load operation substantially no heating medium flows into the at least one further heating element and substantially no heating medium flows from the first heating element into the at least one further heating element. For a control or valve device for use with a radiator, the object is achieved in that an externally operable element is provided with a path translation for opening and closing at least two openings, wherein a first piston and a second piston having smaller dimensions than the first Pistons are hydraulically connected and displaceable in an incompressible medium, or that is provided with two pistons double piston for opening and closing at least two openings, the first piston from the outside confirmed and the second piston is connected to the first piston and the piston can be displaced with each other, or that a first element operable from the outside and rod elements pivotally connected to each other at a hinge point are provided and connected to one another such that the rod elements move along a slope when the first element is actuated, changing the jewe iligen angle to each other. Further developments of the invention are defined in the dependent claims.

This creates a radiator with at least two heating elements, at least one flow and at least one return and with at least one device for separately controlling the supply of heating medium to the at least two heating elements, with a simple way a separate driving and controlling the at least two heating elements, the particular heating plates of a flat or plate radiator, can be, is possible. By providing a connection of at least one further heating element only in full load operation, so if particularly high heating temperatures are needed, such as on cold winter days, a good energy savings is possible. In partial load operation, when only a lower heating temperature is required on the radiator, for example in spring and autumn, only the first heating element is flowed through with warm heating medium. In this way, the volume of heating medium in the heating circuit is reduced. Furthermore, the proportion of radiant heat to the radiator increases, which is positively received by the user. In a partial load operation, therefore, only the charging of the first heating element with heating medium is required and the second or further heating elements are acted upon only when requesting full power with heating medium, so that an energy saving is possible thereby.

The adjusting or valve device may have at least one piston and / or valve cone for opening and closing openings for supplying heating medium to the at least two heating elements. In this way, a separate and successive flow of the at least two heating elements of the radiator is achieved because the at least one piston or valve cone successively release the openings and heating medium can flow into the first and subsequently into the second heating element. If two pistons are provided, in particular in the form of a double piston, it can be provided that heating medium can only flow into the first heating element up to a first predetermined opening gap of the first piston with respect to the first opening and heating medium additionally flows into the second heating element from a second predetermined opening gap can.

For supplying heating medium to the second heating element, at least one bypass line may be provided within the setting or valve device and / or outside thereof. In particular, it is possible to supply heating medium from the setting or valve device to an upper channel of the at least one further heating element or to supply heating medium from the setting or valve device to a lower channel of the at least one further heating element. The inlet into the second heating element can take place with the valve open via an extended bypass line in the form of a pipeline into the lower channel of the second heating element.

Advantageously, the flow is fluidly connected to the first actuator or valve device. The inflow of heating medium to the control or valve device and the return of heating medium in the heating circuit can be carried out by a centrally arranged in the central region of a lower, usually approximately horizontally disposed channel of the radiator distributor. In this case, the return line can be flow-connected to the first heating element or be in line-open connection. It is also possible that the return takes place via a return connection from both heating elements, in particular lower channels of both heating elements open into this return connection.

By providing the return port only on the first heating element, which is first supplied with heating medium, no flow through the second heating element is required to allow the return of heating medium. Thus, it is not necessary, only for the return of the heating medium to flow through the second or further heating element with this. If the return flow connected only to the first heating element, advantageously a connecting channel or element for returning heating medium from the second in the first heating element in a lower lateral region of the actuating or valve means opposite side of the radiator is provided.

When arranging the flow and the return port in the lateral region of the radiator, the bypass line along an upper Heizmediumkanal are directed to a lateral Abstandungs- and / or connecting element for connecting the heating elements. Furthermore, it is possible for the bypass line to conduct heating medium to a spacer and / or connecting element, which is mounted in a line or flow-open manner at any point between upper channels of the two heating elements. The bypass line can also be s-line-shaped and extend from the arranged at the top of the radiator actuator or valve means to the lower channel of the second heating element. A flow or line open connection with the lower channel or the second heating element can take place at any point, in particular in the central region of the channel or in the middle lower region of the heating element.

Advantageously, the spacer and / or connecting element which is arranged between the upper channels of the heating plates in the area opposite the setting or valve device and allows access to the second heating element via the above arranged with respect to the radiator bypass line, the first heating element except for one closed minimum opening for venting the first heating element.

Depending on the arrangement of the adjusting or valve device or the thermostatic valve on the right or left end side of a heating element, the flow can be arranged so that it penetrates the flow-connected to the first heating element return. As a result, a connection to the control or valve device is possible, but also with possibly provided on the radiator further control or valve devices, if desired, depending on the design of the control or valve device. By providing a penetration of flow and return, wherein the return flow is connected to the first heating element, a compact and at the same time uncomplicated construction is achieved in which a direct connection of several control or valve devices with the flow connection is possible, these separated can supply the individual heating elements with heating medium. By connecting all adjusting or valve devices with the flow connection heating medium can flow into all heating elements as required in a simple manner, if this is especially true at Full load operation is desired. Furthermore, any arrangement of the control or valve devices on the radiator is possible, so that they are on the one hand easily accessible and on the other hand easy to operate. This is the case with most of the prior art DE 10 2007 036 141 A1 disclosed embodiments not the case, since the thermostats are closely adjacent to each other and partly not so well positioned.

In particular, a radiator may be provided, the flow and return are designed as a central connection. By providing the center connection, a greater flexibility of the arrangement of adjusting or valve devices on the heating elements or the radiator is also possible. Alternatively, the arrangement of flow and / or return to a lateral mostly lower end of the radiator is possible.

The adjusting or valve device can be designed as a thermostatic valve. Furthermore, it is possible to form the setting or valve device as an electrically and / or electronically driven actuator, in particular electromechanical actuator, in particular as an electromechanical actuator. Such an electromechanical actuator can be controlled in particular via a likewise provided thermostatic valve for the separate control of at least two heating elements, in particular heating plates. In these embodiments, the thermostatic valves or thermostatic valve and electromechanical actuator are connected to the flow connection, so that a demand-based direct supply of heating elements with heating medium is possible.

It is also possible that the adjusting or valve device comprises a hydraulically driven actuator. Here, the provision of a hydraulic transmission is possible, whereby two non-mechanically interconnected pistons are moved with different dimensions in an incompressible medium. The adjusting or valve device may hydraulically connected to an externally operable first piston and a second piston having smaller dimensions than those of the first piston in an incompressible medium and slidable with each other. The one about Thermostatic head operable first piston is advantageously arranged in a common housing, which may in particular be made of plastic or a similar material, slidably disposed with the piston with smaller dimensions. The ratio of the two pistons to each other may be 16 mm to 5 mm, for example. About a suitable incompressible medium, a hydraulic translation takes place such that at a displacement of the larger piston of eg 3 mm, the smaller piston axially displaces, for example, 10 mm. Advantageously, a return spring element, in particular compression spring element, is provided in operative connection with the second piston for moving back into its predeterminable starting position. If the thermostatic head is adjusted to open the thermostatic valve, the smaller piston and thus also the larger piston on the compression spring element moves back to its original position. The compression spring element is advantageously provided on a fixed part of the adjusting or valve device, in particular its housing, supporting.

By providing such a hydraulic transmission, greater degrees of freedom result, in particular, different predeterminable opening cross-sections of the successively controlled channels for supplying heating medium to the at least two heating elements and a better separation of the two channels via the two pistons. Advantageously, the displacement of the piston can be varied as desired over the piston surfaces, so that different valve characteristics are possible and different variants of adjusting or valve devices can be formed. This can on the one hand be part of a thermostat unit for the radiator. On the other hand, it is possible to form the control or valve device as a separate unit and insert between the valve and thermostat for a radiator. The hydraulic adjustment unit can thus be screwed as a separate module between the valve and the thermostat.

The actuator or valve device may further comprise an actuator based on a mechanical translation. The principle of actuation and training can here be similar to a so-called Nürnberger scissors, ie a joint chain. An externally operable first member and rod members pivotally connected to each other at a hinge point may be provided and connected with each other so that the rod members move along a slope upon actuation of the first member while changing the respective angle with each other. Similar to the hydraulic transmission, it is possible to increase the displacement of a piston for closing and releasing channels for supplying heating medium to the heating elements and integrating in a valve block. Advantageously, an actuatable via a thermostatic head annular plate can be moved and thereby move the rod element arrangement, which is in particular in the form of a tripod, along a tapered circumferential surface or conical surface. Due to the consequent constriction and the angular position of the pressure rods results in a Wegerhöhung hinged in the hinge point piston.

A return spring element, in particular tension spring element, may be provided in operative connection with the hinge point for moving back the rod elements into their predeterminable starting position. The return stroke of the piston then takes place by the preferably approximately centrally with respect to the piston end arranged Zugfederelement. The rod element arrangement or the tripod slides along the slope back into the starting position, in which the valve is preferably open.

The rod elements can be made of plastic and / or metal, in particular of plastic, forming film hinges in the region of joint connections.

In the mechanical translation, there are thus large degrees of freedom with respect to the opening cross sections of the successively controlled channels for supplying heating medium to the heating elements and a better separation of the two channels via the driven piston. About a change in the slope of the surface along which moves the rod element arrangement or the angle of the individual rod elements to each other, the adjustment can be advantageously varied as desired. As a result, the provision of various Ventilcharateristiken possible, so that application-specific suitable variants of control or valve devices can be formed.

Just like the hydraulic adjustment unit, the mechanical adjustment unit can be provided as a separate assembly between the valve and the thermostat, in particular screwed. Furthermore, of course, the forming is possible as part of a thermostat unit for the radiator here.

The adjusting or valve device may further comprise a thermally driven or drivable actuator, in particular an expansion capsule. Since a temperature gradient arises from an upper to a lower horizontal water channel of the first heating element, the expansion capsule, upon reaching an adjustable temperature of the heating medium, can clear the path into the second heating element and, conversely, close it again.

Furthermore, the control or valve device can be designed as a device designed as a differential pressure control device. The device designed as a differential pressure control can supply a heating medium volume flow from the first heating element to the second heating element to supply the second heating element in a pressure-dependent manner. In this case, instead of in particular an electromechanical actuator, in particular, a valve unit can be provided which, depending on the pressure, branches off a volume flow for the at least one further heating element, in particular the second heating plate, from the first heating element, in particular the first heating plate. The device may be closed, for example, at partial load and be open at full load, so when fully open thermostatic valve as further provided for the supply or control of the first heating actuator or valve device. A connection of such designed as a differential pressure control device with the flow is thus not required. Rather, in this case only one adjusting or valve device, in particular in the form of a thermostatic valve, connected to the flow.

The adjusting or valve device can be designed so that two at an angle, in particular an angle of 90 ° or another angle, mutually staggered channels of the control or valve device for supplying heating medium to the individual heating elements are controlled separately. The adjusting or valve device thus has two openings arranged at an angle to one another, which face the channels, which can be released one after the other. The heating medium flow is advantageously supplied to the first heating element, with which the return line is connected. The at least one further heating element can be supplied with heating medium via a riser pipe which can be connected or connected to the one duct from the side of the arrangement of supply and return, in particular from the underside of the heating element. It can be a Verstellwegerhöhung particular by providing a translation, as already described above, be provided.

It can be provided one of the number of heating elements corresponding number of adjusting or valve devices. In particular, at least two adjusting or valve devices may be provided, wherein the second actuating or valve device opens upon application of a hydraulic pressure. Advantageously, the two actuating or valve devices can be connected or connected to one another via a first riser. If a hydraulic pressure is applied to the second actuating or valve device via this riser, it opens. The flow is advantageously connected in this embodiment with two adjusting or valve devices, wherein preferably a further riser between the flow and the first adjusting or valve device is arranged. The flow is so far branched to the two control or valve devices. To the first adjusting or valve device are advantageously in turn connected to each other at an angle of in particular 90 ° or another angle channels for the supply of heating medium to the heating elements, wherein the one comprises said first riser.

Between two heating elements advantageously at least three spacer and / or connecting elements are provided. The spacer and / or connecting elements may comprise at least one device for closing and / or flow reduction. This is a disconnect and Spacing the heating elements, in particular heating plates, possible to control these separately. For example, the spacer and / or connecting elements may be formed as T-pieces with at least two openings for connection to the at least two heating elements and with at least one further opening. The further opening may be provided with a control or valve device or be used to vent the radiator or be closed with a closure element. Conventional spacer elements and / or connecting elements of radiators can be used here, so that, in contrast to the prior art, in particular the DE 10 2007 036 141 A1 , inexpensive spacer and / or fasteners can be used. Only these are provided in the region of two openings for optionally required flow reduction or for closure with corresponding diaphragms or closure devices.

Such a diaphragm element for flow reduction advantageously has no central opening, but distributed on the edge a number of outbreaks or openings. As a result, a venting of a radiator at the highest point is possible, since the one or the furthest upstream outbreak or opening can serve this purpose.

In order to make it possible to vent the heating elements, at least one upper cross connection or at least one spacer element and / or connecting element of the heating elements can be partially closed by means of a diaphragm element of the type known as baffle plates or provided with a special vent valve insert.

The device for reducing the flow in the form of a diaphragm element can also be adapted to the type of radiator or be, ie at its length or height and the number of heating elements, so that a correspondingly desired heating characteristics can be achieved here. In particular, a small flow of heating medium from the one into the at least one other heating element is possible by the diaphragm element, so that the other heating element can be slightly heated. The flow reductions otherwise serve to obstruct the outflow of hot water into the second heating element, whereby usually no complete closure will be provided in order not to hinder a venting of the radiator.

The adjusting or valve device may be provided with a device for KV value presetting. A KV value is understood to mean a certain flow rate at a given differential base pressure. The KV value preset device is an aperture element. This is preferably arranged rotatably adjustable and provided with openings. The openings of the panel element are further advantageously arranged or arranged so that they at least partially cover at least two channels for supplying heating medium in the at least two heating elements. About such a rotatable diaphragm element or such a rotatable sleeve adjustment of the possible flow opening in the channels for supplying heating medium to the heating elements is possible. The KV value presetting is used for the one-off hydraulic adjustment of a radiator in a heating circuit by setting the possible volume flow over the set slot or the pinhole. As a material for the panel element is a little corrosion-prone material, such as brass. Especially when providing a steel housing, the piston area may be formed together with the adjustment as pressed-brass shell.

The KV value presetting device can furthermore be arranged on or in the region of the return flow of the radiator, in particular in a connecting bridge or another obturator.

The frontal contour of one or the piston or a valve piston for the separate opening of channels for the supply of heating medium to the heating elements is advantageously formed cone-shaped and / or planar surface. Preferably, a nose-shaped projection is provided for fastening a valve stem. Such a nose-shaped projection also has a favorable effect on the noise when flowing through the thermostatic valve. As further advantageous proves the provision of a substantially annular contact surface to a valve seat.

For separately opening channels for supplying heating medium to the heating elements, a stepped piston provided with an oblique surface may be provided. Such a stepped piston offers the possibility of the channels to be controlled without a lateral offset, so lying in a plane to open and close. In order to ensure a clear and desired orientation of the inclined surface due to the provision of the inclined surface, an anti-rotation device for the stepped piston is advantageously provided.

The adjusting or valve device may comprise a pressure valve, wherein the pressure valve may be electrically, electronically, thermally or hydraulically controllable.

Furthermore, the adjusting or valve device may be formed as at least partially spherical element or as at least partially block-shaped element. Here, the adjusting or valve device as a partially spherical element in particular of a plastic and / or metal. As a partially block-shaped element, it consists in particular of a metal, e.g. made of brass.

If a second control or valve device is arranged on a location otherwise provided for venting a radiator, venting can take place via the control or valve device, wherein the positioning of the thermostatic head with the control or valve device in a secured venting position is basically possible.

If a thermostatic valve or an adjusting or valve device is closed for a long time, it can happen that the piston gets stuck. Here, the aforementioned return spring elements serve to retract the pistons to their original position. Therefore, an overload protection is advantageously provided in the thermostatic head, which prevents mechanical damage.

If the radiator is arranged in a room, in particular on a room wall, the heating plate 10 is directed towards the room and the heating plate 11 to the room wall. The heating plate 10 thus forms the so-called. Front plate and the heating plate 11, the so-called. Rear plate.

The two heating plates are connected to each other by four Abstandhalte- and / or connecting elements 2, 3, 4, 5 and at the same time kept at a distance from each other. The fourth spacer and / or connecting element 5 is in FIG. 1 However, hidden by the heating plate 10, so not visible. The four Abstandhalte- and / or connecting elements are each T-shaped and each have three openings.

Here, the opening 30 is provided to the front heating plate 11 with a diaphragm element 33, which with a number of small openings or through holes 34 at its circumferential outer edge 36 is provided to allow a flow reduction for a passage of heating medium in the rear heating plate 11. Via the opening 32 in the spacer or connecting element 3, a venting of the radiator is possible.

The likewise T-shaped spacer or connecting element 4 has an opening 40 to the front heating plate 10, an opening 41 to the rear heating plate 11 and a further opening 42 which can be provided with a closure element or is.

Further, the radiator 1 is provided with a center port 8, which includes a flow port 80 and a return port 81. Flow connection and return connection are connected to each other via a connecting element 82, wherein the return connection is further connected to an L-shaped branching off from this connecting element 82 section 83 via an opening 84 with the front heating plate 10. Connected to the connecting element 82 is a line section 86, which is passed through the return port 81. The line section 86 is further connected to a riser 95, which leads to the control or valve device 6.

Like the detailed representation in FIG. 2 can be removed, are provided in the spacer and / or connecting element 2, a channel 24 to the front heating plate 10 and a channel 25 to the rear heating plate 11 and a channel 27 to the riser 95 and a valve piston 68 openable and closable, so that heating medium from the riser 95 via the channel 27 in the channel 24 to the front heating plate 10 and possibly via the channel 25 can flow into the rear heating plate 11, if necessary. The valve piston is in normal partial load operation, so if only lower temperatures are required, the thermostatic valve 6 is set only to a low level, only so far postponed that it releases the channel 24 at least in part, to flow heating medium in the heating plate 10 to let. Only at full load operation, so if high temperatures are demanded or the thermostatic valve 6 is set to a high level, the valve piston is moved so far that he also at least partially releases the channel 25, so that heating medium also can flow into the heating plate 11. Thus, a needs-based supply of the two heating plates 10, 11 with heating medium on the only one thermostatic valve 6 is possible, in most areas of Germany annually only about 5% of the heating time full load operation is required, so that by heating only the one hot plate 10 in 95% of the time energy savings compared to the known supplying both heating plates can be achieved with heating medium.

FIG. 3 shows a second embodiment of the radiator 1, in the flow connection 80 and return port 81 on - here standing in front right side - lower end of the radiator 1 are arranged. Flow connection 80 and return port 81 are connected to each other via a tab 85, a flow connection in the sense of an overflow of the flow through the return passage is not provided here. The return port is connected directly to the spacer and / or connecting element 4 or arranged on the underside thereof. The return port 81 is, as in the first embodiments, only connected to the front first with heating medium supplied heating plate 10 - here via the opening 40 in the spacer and / or connecting element 4 - fluidly connected, so that a Heizmediumaustritt always through the front heating plate 10th he follows.

FIG. 4 shows a detailed view of the radiator FIG. 3 , This can be seen that a valve piston 68 is provided in the control or valve device 6, which controls the two channels 24, 25, that can release and lock one after the other to target only the control or valve device 6, the front and rear heating plate be able to supply with heating medium. The heating medium passes through a riser 98 in turn into the channel 27 of the control or valve device to get from there into the channel 24 and possibly the channel 25 can.

In the spacer and / or connecting element 3, the diaphragm element 33 is provided in the opening 31 for reducing the flow toward the heating plate 11. Again, the aperture element 33 is in turn provided at its peripheral outer edge 36 with outbreaks or passage openings 34. By the Providing such distributed on the circumference of the aperture element outbreaks or openings, it is better possible to vent the heating plates through the opening 32 of the spacer and / or connecting element 3, since the air can escape via the arranged at the highest point through hole 34. As a result, a better ventilation than in the use of a provided with a central opening aperture element is possible, since by such the air can emerge only bad. Furthermore, the unwanted heating of the rear heating plate 11 is very well avoided by the small slit-shaped or triangular outbreaks or passage openings 34.

In the FIGS. 5 and 6 a vent valve housing 110 is shown. This can be provided instead of a diaphragm element 33 in arrangement in an opening 30 or 31 of the spacer and / or connecting element 3 between the two heating plates 10, 11. The vent valve housing 110 is formed in principle as a spacer and / or connecting element, in which a special insert 111 is inserted or pressed, which creates channels 112, 113, 114 within the vent valve. The insert 111 has the first channel 112 to the front heating plate 10 and the second channel 113 to the rear heating plate 11 and the third channel 114 in the outward direction. The two smaller channels 112, 113 are offset from one another. In an intermediate wall 115 within the insert 111 of the vent valve housing 110, an opening 116 is provided, which connects the two channels 112 and 114 with the channel 113. In the region of the opening 116, the channel 113 is stepped to assist in directing the air here in the direction through the channel 114 to the outside. Since the channel 112 is formed closer to, and directly adjacent to, the channel 114, and otherwise by the displacement to the channel 112, air entry from the channel 112 into the channel 113 will hardly occur, this channel 112 extends straight with only a small step in the region of the transition to the intermediate wall 115.

One to the training of the control or valve device 6 after Figure 1 to 4 alternative education is in FIG. 7 and R is shown with a mechanical adjustment unit 160. The structure of the radiator otherwise corresponds approximately to the according FIG. 1 , In the setting or valve device 6 in FIGS. 7 and 8 is a mechanical translation provided to increase the displacement of the piston. This comprises an annular plate 161 which can be actuated by the thermostatic head 64 and is correspondingly in communication therewith. Furthermore, a joint chain in the manner of a Nuremberg scissors from three rod elements 162, 163, 164 is formed. These are hinged together in a hinge point 165. The hinge point 165 is provided with respect to the rod members opposite to the annular plate. The rod elements are arranged obliquely, in principle along a tapered circumferential surface or a conical surface. The rod elements change when pressure is applied as pressure rods, the angular position in space and also to the annular plate 161. End of the rod members 162, 163, 164 in the region of the pivot point 165, a piston 166 is articulated. By changing the angular position of the rod elements in the room, there is a displacement increase on the part of the piston 166 during its displacement.

The piston 166 can close both the channel 24 and the channel 25, so that the supply of heating medium in turn can be specifically approved or prevented in the heating plates.

If the piston 166 is to be returned to its original position, this is effected or at least supported by a tension spring element 167. This is arranged approximately centrally between the rod elements 162, 163, 164. Due to the spring force, the rod elements again change their angular position in space and are moved along the slope. The valve can therefore be opened again.

The rod elements may consist of a plastic and the respective joints in the hinge point 165 and the joints in the region of the connection to the annular plate 161 may be formed as film hinges.

The advantages of this mechanical translation are in principle the same as those of a hydraulic, the below to the FIGS. 17 and 18 is illuminated in more detail, since in both the opening cross sections of the successively controllable channels 24, 25 via the adjustment and the movement of the piston variable are so that there are great degrees of freedom in training. The displacement of the piston 166 can be arbitrarily varied by changing the angles of the rod members, so that the adjustment of various valve characteristics is possible.

The mechanical adjustment unit 160 can, as in the FIGS. 7 and 8 shown integrated into the control or valve device 6 or as a separate unit, as in FIGS. 9 and 10 shown to be trained. In FIG. 10 the training is shown as a separate assembly in the form of an adapter element 168, which is inserted between the actual valve and the thermostatic head 64, in particular, as shown, is screwed.

Unlike the embodiment according to FIG. 7 is after the radiator FIG. 9 the diaphragm element 33 is arranged in the opening 31 of the spacer and / or connecting element 3.

The FIGS. 11 and 12 show an embodiment of the adjusting or valve device 6, which is provided with a KV value preset means 100. This serves the one-time hydraulic balancing of the radiator 1 in a heating circuit. It comprises a sleeve-shaped diaphragm element 101 with one or two slots 102, wherein the second slot is provided for a further heating element. The slot or slots is / are arranged in the region of the channel 24. The diaphragm element 101 is rotatably mounted and formed in the manner of a pinhole, wherein the respective slot is formed non-uniform, so that upon rotation of the diaphragm element, the opening size and thus the volume flow of heating medium in the channel 24 can be varied. The sleeve-shaped aperture element 101 surrounds the remaining parts of the adjusting or valve device 6, which in FIG. 12 a hydraulic actuator comprises. Not only can a different type of actuator be provided here, but also an actuator or valve device can be combined with the diaphragm element without a possibility of increasing the displacement.

The KV value pre-adjustment device 100 can also be provided on or in the region of the return port 81, in particular in the section 83. For the diaphragm element, a brass material can be used to prevent corrosion when providing a steel housing of the adjusting or valve device. It can also be the piston area incl. Adjustment be formed as a pressed-brass sleeve or in a bolted to the return gate or otherwise fixed thereto actuator.

The diaphragm element 33 is in the embodiment according to FIG. 11 in turn arranged in the opening 31 of the spacer and / or connecting element 3.

In FIGS. 13 and 14 a further embodiment of the radiator 1 is shown. In contrast to the previous figures, a further riser 96 is arranged between the spacer and / or connecting element 4 and the adjusting or valve device 6. The riser 96 is only used to control the rear heating plate 11. The control or valve device 6 is also used to control the heating medium supply to both the front and the rear heating plate. Like the detailed representation in FIG. 14 can be removed, is provided in the spacer and / or connecting element 2, only the channel 24 to the front heating plate 10 and a valve piston 68 can be opened and closed. The spacer and / or connecting element 4 is designed to be closed to the front heating plate 10. However, the valve piston 68 also serves to open and close a channel 26 to the riser 96 back to let this heating medium flow into the rear heating plate. The two channels 24 and 26 are arranged at an angle of about 90 ° to each other, as in FIGS. 13 and 14 to see. When the channel 26 is released, heating medium can flow into the rear heating plate 11 through the riser 96. However, the return port 81 is also connected to the front heating plate 10 so that heating medium, which flows into the rear heating plate 11 in particular at full load operation, flows through one of the two spacer and / or connecting elements 4 and 5 back into the front heating plate 10 , As already in the embodiment according to FIG. 1 is in the spacer and / or connecting element 3 turn the shutter member 33 disposed in the opening 30 to reduce the flow to the rear heating plate eleventh

The FIGS. 15 and 16 show a variant of the embodiment of the radiator 1 after FIGS. 13 and 14 , In addition to the riser 96, a branch line 97 leads from the flow port 80 to the spacer and / or connector 4, which in this embodiment comprises a pressure valve 72. The riser 96 also leads to the pressure valve 72. The channel 26 (see FIG. 16 ) as a result, to a control channel, because as soon as a hydraulic pressure applied to this control channel, opens the pressure valve 72. By opening the pressure valve 72, heating medium from the flow port 80 via the branch line 97 in the rear heating plate 11 to flow. A return of heating medium in the return port 81 is in turn provided only from the front heating plate 10, so that the heating medium from the rear heating plate 11 through the spacer and / or connecting element 5 can get back into the front heating plate. In the spacer and / or connecting element 3, in turn, the diaphragm element 33 is provided for reducing the flow to the rear heating plate 11 in the opening 30. The adjusting or valve device 6 is otherwise, for example, as in FIG. 14 shown formed. The pressure valve 72 is formed block-shaped, but may also be spherical, as the other spacer and / or connecting elements. The spherical configuration of the pressure valve may consist of a plastic material, the block-shaped of a metal, in particular brass. The pressure valve can be controlled electrically, electronically or thermally in addition to the aforementioned hydraulic control.

One to the training of the control or valve device 6 after FIGS. 7 and 8 alternative training with hydraulic translation st in the FIGS. 17 and 18 shown. According to FIGS. 17 and 18 is the adjusting or valve device 6 is formed with a hydraulic actuator 60 with two pistons 61, 62. This may be better FIG. 18 be removed. Both pistons 61, 62 are arranged in a common housing 63 in an incompressible medium, wherein there is no mechanical connection between the pistons 61, 62. The piston 61, which can be actuated via the thermostatic head 64, has larger dimensions than the piston 62. For example, the ratio of the piston can be 16 mm to 5 mm. Due to these different dimensions, a hydraulic translation is created so that at Actuation of the thermostatic head and thus shifting the larger piston by a small amount of the smaller piston is shifted by a multiple of this amount, eg when moving the larger piston by 3 mm, the smaller is shifted by 10 mm.

In order to retrieve the smaller piston when opening the thermostatic head, a compression spring element 65 is provided, which is supported on the housing 63, such as FIG. 18 can be removed. When opening the thermostatic head of the piston 62 is pushed back by the compression spring element 65 back to its original position, with the hydraulic coupling and the piston 61 returns to its original position. The spring force of the return spring or the compression spring element with the valve closed is, for example, 45 N. In particular, when the valve is closed for a long time, the piston can hang tight, so that the spring retracts the valve again. In order to avoid that the valve or the piston lifts off, which may be the case at a pressure of about 3 bar, an overload protection can be provided in the thermostatic head, which prevents mechanical damage. Such is in FIG. 18 but not to be seen.

The frontal contour of the valve piston 62 is in the embodiment according to FIG. 18 conical. However, it can also be plane surface or a mixture of both shapes. As FIG. 18 can be seen, a nose-shaped projection 66 is formed, which has a favorable effect on the noise. Furthermore, an annular contact surface 67 is formed to the valve seat, to allow optimal installation here. As material for the pistons eg EPDM with 90 Shore can be used.

By providing the hydraulic transmission, the opening cross sections of successively released channels 24, 25 in the spacer and / or connecting element 2 can be varied. The separation of the two channels 24, 25 which lead in to the two heating plates 10, 11 and allow a flow of heating medium in these two heating plates 10, 11 can therefore be done very accurately. The adjustment of the piston can be over the Choice of the dimension of the piston area vary as desired, so that different valve characteristics can be set here.

Instead of in FIG. 18 shown embodiment of an integration of the hydraulic actuator 60, this can also be designed as a separate unit and arranged between the valve and thermostatic head.

Corresponding FIG. 20 is connected to the connecting element 82, a pipe system 9, wherein the spacer or connecting element 4, a line section 90 is guided, connected to a riser 91, which led to the Abstandungs- or connecting element 2 and thus to the adjusting or valve device 6 is. Thus, both the front and the rear heating plate can be supplied with the flow of the heating medium, wherein a return is provided only from the front heating plate 10. The temperature of the front and rear heating plate 10, 11 can be carried out selectively separated by the two control or valve devices or thermostatic valves 6, 7, wherein the driving characteristic for the rear heating plate 11 can be influenced in particular via the shutter member 33, if provided by the Thermostatic valve 7 no warm flow, so no heating medium is passed directly into the rear plate, but only heating medium, which has already flowed through the front heating plate 10, in small quantities on the shutter member 33 may possibly enter the rear heating plate 11. Depending on the height and length of the radiator or the heating plates 10, 11 of the radiator, the shutter member 33 can not only be arranged in variable height with respect to the heating plates, but also with regard to its opening 34 are adapted to the size of the radiator.

In the FIG. 19 shown variant of the radiator 1 is constructed in principle similar to the embodiment according to FIG. 1 , In contrast to this, however, no mechanical or electromechanical actuator and no electromechanical actuator is provided, but rather a pressure valve 71. This serves to control the supply of heat to the rear heating plate 11. The pressure valve is constructed so that thereby a pressure difference control is possible, wherein a pressure-dependent flow is diverted from the front heating plate 10 for the rear heating plate 11. The pressure valve is thus closed at partial load operation and opened at full load operation, thus open at full opening of the thermostatic valve or the control or valve device 6, so that in this state, if so much heat is required, via the pressure valve 71 in the so-called. Bypass operation warm heating medium can get into the rear heating plate 11.

The pressure valve 71 is not connected directly to the flow connection 80. Thus, the riser 95 is guided directly from the flow connection via the return connection 81, that is from the connection element 82 to the spacer or connection element 2 of the control or valve device 6.

In order to avoid a direct flow of heating medium from the front plate 10 to the rear heating plate 11 via the spacer 5, in the opening 50 is an aperture member 54 having a number of small passage openings 55 at the outer edge, similar to the aperture member 33, provided. In the other opening 51 to the rear heating plate 11, no such diaphragm member is provided.

In FIG. 19 the opening 20 of the spacer and / or connecting element 2 to the front heating plate 10 is opened, whereas the opening 21 is closed to the rear heating plate 11 by a closure element 23. The same applies to the embodiment according to FIG. 20 ,

The T-shaped spacer or connecting element 4 there has an opening 40 to the front heating plate 10, an opening 41 to the rear heating plate 11 and a further opening 43 on which a further adjusting or valve device 7 is arranged. This is also designed as a thermostatic valve. It is thus used to control the heating medium supply to the rear radiator 11. It is thus no longer provided only a control or valve device, but a number of heating plates corresponding number of control or valve devices.

In the opening 40 to the front heating plate 10, a further closure element 43 is arranged to allow only a flow of heating medium into the rear heater 11 here.

The fourth spacer 5 is in FIG. 20 not shown, however, is also T-shaped and connected with its opening 50 with the front heating plate 10 and with its opening 51 with the rear heating plate 11 and has a further opening 52 which is optionally closable.

To both adjusting or valve devices 6, 7, a pipe system 9 is guided coming from the flow port 80, which provides a line section 90 as a branch to the control or valve device 7 and the riser 91 to the control or valve device 6.

If, instead of only two heating plates 10, 11, further heating plates are provided here, not only can further adjusting or valve devices be provided for this purpose, but also a flow through the return connection through the supply, so that targeted heating of the respective individual heating plates is possible ,

FIG. 21 shows a variant of the radiator 1, in which, in contrast to the embodiment according to FIG. 20 for driving the rear heating plate 11, an electromechanical actuator 70 is provided. The remaining structure of the radiator 1 corresponds to the in FIG. 20 shown. The electromechanical actuator 70, which serves to control the rear heating plate 1, is controlled via the thermostatic valve or the control or valve device 6. In this way, in turn, a separate control of the two heating plates 10, 11 and also a larger number of heating plates of the radiator is possible. The control characteristic for the rear or further heating plate or heating plates can in turn via the aperture element 33 and its openings 34, but of course also take place via the electromechanical actuator 70, with an adaptation to the respective height and length of the radiator or its heating plates is possible here.

Instead of the arrangement of the electromechanical actuator 70 on the spacer or connecting element 4, this can of course also be arranged on the spacer or connecting element 3 or 5. If the electromechanical actuator 70 is arranged on the spacer or connecting element 3, a venting device is advantageously integrated into the electromechanical actuator, in order to further enable venting of the heating element or its heating plates.

In the embodiment of the radiator 1 according to FIG. 22 the second adjusting or valve device 7 is now arranged on the spacer or connecting element 5. Therefore, the opening 50 of the spacer or connecting element 5, which is directed to the front heating plate 10, provided with a closure member 53 to allow only a control of the rear heating plate 11 via the thermostatic valve 7 and the setting or valve means 7 ,

From the flow connection 80, a line section 92 is further guided to the spacer or connecting element 5. Instead of the combination of the line section 90 and the riser 91, only one riser 92 is led to the spacer or connecting element 2 and thus the thermostatic head or the control or valve device 6.

According to the spacer or connecting element 5 in the embodiments according to FIG. 20 and 21 is now the spacer or connecting element 4 without further closure elements with its openings 40, 41 connected to the front heating plate 10 and rear heating plate 11. The opening 42 is left open in the illustration, but is optionally closed by a closure element to prevent the escape of heating medium. A venting of the heating plates 10, 11 and the radiator can continue via the spacer or connecting element 3 and here its opening 32. Only to avoid an inflow of heating medium through the spacer and / or connecting element 2 in the rear heating plate 11, the closure element 23 is in turn arranged in the opening 21.

In the embodiment according to FIG. 23 the thermostatic head or the adjusting or valve device 7 is now arranged on the spacer or connecting element 3. The two spacer or connecting elements 4, 5 are therefore completely without closure elements in their directed to the two heating plates openings 40, 41 and 50, 51 is provided. The two openings 42, 52 are also left open. Here, a closure element is advantageously inserted to prevent leakage of heating medium, which, however, in FIG. 4 not shown.

In addition to the riser 93 to the thermostatic valve or the control or valve device 6, accordingly FIG. 22 , now a riser 94 is guided to the thermostatic valve or the control or valve device 7. To be able to control only the rear heating plate 11 via the thermostatic valve 7, the opening 30 of the spacer or connecting element 3 is provided with a closure element 35. In order to further allow venting of the radiator or the heating plates of the radiator, the adjusting or valve device 7 comprises a venting device, however, in FIG. 23 not shown.

It is in turn possible via the two risers 93, 94, in turn, to direct the warm flow of heating medium both in the front and the rear heating plate, in turn, the flow passes through the return port, so it is passed over this, resulting in short and easy ways and thus leads to a compact and simple construction.

In each of the embodiments, the heating medium via the channel 27 can get into the control or valve device 6 and from there into the channels 24 and possibly 25 or 26th

The valve lift / Kelvin can be approximately 0.23 mm, for example, in the illustrated and described control or valve devices. The differential pressure of a valve should advantageously not exceed 0.2 bar in any operating state, otherwise flow noise may occur.

Each of the above-mentioned and shown in the figures, the valve piston has, at least in its directed to the channel 27 end an approximately conical shape of the end face with a circumferential annular contact surface for resting on the valve seat and with a nose-shaped projection, as already mentioned for the valve piston 62. Instead of the conical shape can also be provided a flat planar shape or a spherical or a mixed form there.

The Abstandhalte- and / or connecting elements, in particular the Abstandhalte- and / or connecting element 4, each may be formed as a partially spherical element, as in the FIGS. 1, 2 . 3, 4 . 6 and 14 shown, or as a partially block-shaped, as in the Figures 5 . 8th and 12 shown. In an embodiment as a partially spherical element is particularly suitable for a design in plastic, but also in another material, such as a metal or a combination of these materials, in the embodiment as a partially block-shaped element is suitable training, especially in metal, especially in brass , Of course, other materials of sufficient strength, incl. Material combinations, can be used here.

Another variant of the wiring and the control or valve device 6 is in FIG. 24 shown. Here is how FIG. 25 can be removed, the adjusting or valve device 6 is provided with a double piston 200. This comprises two by a rod 210 coupled to each piston 201 and 202, which is provided for opening and closing two openings or channels, namely the channel 24 and the opening to the front heating plate 10 and an opening 203 to a bypass line 204 via the heating medium in the rear heating plate 11 can be passed. As a result of the mechanical coupling of the two pistons 201, 202, these can each be moved together when adjusting the adjusting or valve device 6.

Flow and return ports are arranged laterally on the radiator 1 in this embodiment. From the flow connection 80, a riser 205 is guided to the control or valve device 6. It ends in the distance and / or connecting element 2, offset by about 90 ° to this and the adjusting or valve device 6 and the extension of this outgoing bypass line 204. The mouth opening in the Abstandhalte- and / or connecting element 2 is designated by the reference numeral 206.

The opening or the channel 24 can be closed and opened by the first piston 201, to allow heating medium from the riser 205 to flow into the front heating plate 10. The opening 203 to the bypass line 204 can be opened and closed by the second piston 202 to flow heating medium from the riser into the rear heating plate 11. The heating medium passes from the flow through the riser 205 at a first opening gap of the first piston 201 through the channel 24 in the front heating plate 10. If the double piston moved further, can reach from a second predeterminable opening gap heating medium in the rear heating plate 11.

About the S-shaped bypass line 204, the heating medium via the spacer and / or connecting element 5 or, if one is provided, in the region of another spacer and / or connecting element 207 in the lower region of the two heating plates or the radiator in get the rear heating plate 11. For this purpose, an opening 208 to the front heating plate 10 is provided with the diaphragm element 33. A flow of heating medium from the front heating plate 10 in the rear heating plate 11 is thereby substantially prevented or at least reduced. In a corresponding manner, the two further spacer and / or connecting elements 3 and 5 each have such a diaphragm element 33 in the openings 30 and 50. Although in principle both the spacer and / or connecting element 5 and the spacer and / or connecting element 207 may be provided, however, one of the two may be dispensed with, in particular the spacer and / or connecting element 207, in order to provide a space in the edge region of the radiator to obtain sufficient stability for the heating elements. The spacer and / or connecting element 207 is in FIG. 24 therefore only shown in dashed lines. If provided, it may be provided by the spacer and / or connector 207 may be provided to the spacer and / or connecting element 5, a connecting line 209 and reach either through both spacer and / or connecting elements 5, 207 or only by one of these in the rear heating plate 11.

Reflux of heating medium may occur from the front heating plate or from the rear heating plate through the spacer and / or connecting element 4 and the return flow port 81, respectively.

FIG. 26 shows a further embodiment of the radiator 1, in which two supply and return ports 80, 81, 211, 212 are provided, a lateral and a middle. This structure is therefore suitable for use in a lateral and in a center connection in the floor of a room. The two flow ports 80, 211 are connected by a connecting line 213, which leads through the return port 212. Again, the double piston 200 is provided, however, a bypass line 214 extends in the upper region of the radiator 1 of the spacer and / or connecting element 2 to the spacer and / or connecting element 3 and / or, if provided, to a further upper Abstandhaltehalte- and / or connecting element 215. The Abstandhalte- and / or connecting element 3 may be provided with the spacer and / or connecting element 215 may be connected thereto via a connection line 216, as in FIG FIG. 26 indicated by dashed lines. In order to provide a stable corner structure of the radiator, in particular the spacer and / or connecting element 3 is provided. However, it is also possible for only the spacer and / or connecting element 215 or both spacer and / or connecting elements 3 and 215 to be provided.

The two spacer and / or connecting elements 3, 215 each have a respective diaphragm element 33 in their openings 30, 217 arranged near the front heating plate. The spacer and / or connecting element 5 has in its directed to the rear heating plate 11 Opening 51 such a shutter member 33. All the aperture elements 33 in turn serve to reduce the flow of heating medium to the other heating plate, ie in the two Abstandshalte- and / or connecting elements 3, 215 to the rear heating plate 11 and in the Abstandhalte- and / or connecting element 5 to the front heating plate 10. A Return of heating medium from the rear heating plate 11 is therefore carried out only by the spacer and / or connecting element 4 or possibly provided at the further return port 212 spacer and / or connecting element 218. A backflow of heating medium from the front heating plate 10 is also carried out These two spacer and / or connecting elements 4 and / or 218. It can also be provided only a return only from the front heating plate 10, so that a lower connection of the two heating plates, for example in the spacer and / or connecting element 5 or if necessary 4, to return the heating medium from the rear to the front heating pl can serve.

Another variant of the bypass line guide is in FIG. 27 and 30 shown. This embodiment is particularly suitable when providing a center connection of the flow and return. The double piston 200 is in turn connected to the adjusting or valve device 6 in the spacer and / or connecting element 3, as in the detail sectional views of the adjusting or valve device 6 in arrangement in the spacer and / or connecting element 3 as a sectional view along the line AA off FIG. 30 in the Figures 28 and 29 is shown. To the Abstandhalte- and / or connecting element 3 leads an L-shaped riser 219 and from this or the adjusting or valve device 6, a likewise L-shaped bypass line 220 to the Abstandhalte- and / or connecting element 5. The adjusting or valve device. 6 is designed here for the left-side attachment to a radiator, in particular FIG. 30 can be removed. In this case, the channel 25 is successively opened or closed by the first piston 201, and the piston 202 serves to successively open and close the opening 221 to the bypass line 220.

In FIG. 28 is the fully closed position of the valve assembly or the adjusting or valve device 6 can be seen, in which the two pistons 201 and 202, each formed differently, the two openings completely close. The piston 201 closes the channel 25 or this lateral opening in the housing of the adjusting or valve device by its outer jacket surface, whereas the other piston 202 closes the opening 221 both by a part of its lateral surface and by its front surface.

How out FIG. 29 can be seen, the opening at the channel 25 is first opened when the double piston is moved. Only after exceeding a further path and the second piston 202 is lifted so far out of the opening 221 that an opening gap 222 is formed, can flow through the heating medium from the mouth opening 223 of the riser 219 in the bypass line 220. This then flows down into the heating plate 11.

In addition to the embodiments shown in the figures and described in the text of the description, numerous other can be formed, in particular combinations of the variants shown and described, in which in each case at least one adjusting or valve means for controlling the supply of heating medium to the heating elements, in particular heating plates , is provided separately from each other. The adjusting or valve device may comprise an externally adjustable first piston and a second piston, which are connected or coupled together mechanically, hydraulically or pneumatically. In particular, a center connection for flow and return can be provided. Further, the flow is fluidly connected to the actuator or valve means and the return flow connected to the first heating element or the first heating plate. The flow can penetrate the return, so the supply via the return port are carried away. Instead of the arrangement of the flow on the left side and the return flow on the right shown in the figures, a reverse arrangement can also be provided.
