Description

The invention relates to a sprinkling device with a carrier device, on which a water dispenser is held with a housing having a water inlet and on which a plurality of nozzles are arranged, which are in fluid communication with the water inlet via a longitudinal channel, wherein in or on the housing at least one outlet chamber is arranged, which is connected on the one hand with at least one controllable nozzle and on the other hand via a first passage to the longitudinal channel, wherein the flow connection between the longitudinal channel and the at least one controllable nozzle by means of a closing body selectively shut off and is releasable, between a blocking position and a release position is shiftable back and forth.

Such irrigation devices are used, for example, as portable or stationary built-in devices for sprinkling lawns, beds or the like. For this purpose, they have a water discharge device with a plurality of nozzles, which are in fluid communication with a water inlet via a longitudinal channel. The water can be released via the nozzles for sprinkling, for example, a lawn.

The water dispenser is often pivotally mounted on a support means of the sprinkler and can be pivoted about the longitudinal axis of the housing back and forth. For pivoting the water discharge device, the sprinkling device usually has a drive device, for example in the form of a hydraulic motor. Such drive devices are known to a person skilled in the art.

In order to be able to influence the size of the area to be covered by the nozzles, in the EP 0 362 558 A2 proposed a sprinkler, wherein some nozzles are each connected to an outlet chamber, which are connected via a passage with the longitudinal channel in fluid communication, wherein the flow connection between the longitudinal channel and each connected to an outlet chamber nozzle with the aid of a closing body can be selectively blocked or released , This makes it possible to interrupt the water supply to some nozzles of the sprinkler, so that no water can be discharged through these controllable nozzles. Thereby, the area to be covered by the sprinkler can be reduced.

The closing body, with the help of which the water supply to a controllable nozzle can be interrupted, is in the sprinkler, which in the EP 0 362 558 A2 is arranged on a piston-like valve spool which is slidably held in the outlet chamber. The passage through which the outlet chamber is connected to the longitudinal channel is arranged in the side wall of the outlet chamber, along which the closing body slides. The closing body has an annular sealing element, which thus slides along a portion of its outer periphery at the edge of the passage. As a result, the ring seal is not insignificantly loaded, it can come in this part of the outer periphery of the ring seal to an abrasion that affects its sealing effect in the locked position of the closing body.

In the DE 10 2006 043 879 A1 a sprinkler is proposed, in which also the water supply to some nozzles by means of a Locking body can optionally be shut off or released. The closing body is designed as a valve slide, which has a flattening. In the area of the flattening, a sealing ring is arranged, which in a blocking position of the valve slide tightly surrounds an outlet leading to a controllable nozzle. At the transition between the blocking position and the release position of the valve slide, the sealing ring slides along the edge of the outlet, so that it can come in this embodiment of the sprinkler to affect the sealing effect of the closing body in a repeated reciprocating motion.

Object of the present invention is to develop a sprinkler of the type mentioned in such a way that the risk of impairment of the sealing effect of the closing body can be reduced.

This object is achieved in a sprinkler of the generic type according to the invention that the closing body is displaceable perpendicular to the cross-sectional area of the first passage.

In the sprinkler according to the invention, the closing body, with the aid of which the water supply to at least one controllable nozzle can be interrupted, be moved perpendicular to the cross-sectional area of the first passage. The closing body therefore lifts off from the edge of the first passage in the transition to its release position, and in its blocking position, it can rest directly on the first passage. Based on the first passage, the closing body thus performs a lifting movement.

It is particularly advantageous if the closing body dips into the first passage in its blocking position.

The first passage can form a valve seat to which the closing body can be applied in its blocking position in a sealing manner.

It is particularly advantageous if the closing body is displaceable parallel to the flow direction of the water flowing into the outlet chamber in the region of the first passage. This has the advantage that the water flowing into the outlet chamber completely surrounds the closing body in the circumferential direction. If the closing body moves from its release position into its blocking position, then the closing body increasingly approaches the first passage, so that the flow cross-section available to the water flowing into the outlet chamber is increasingly reduced. This has the consequence that the flow velocity is increased, and this in turn causes dirt particles, which are deposited on the first passage or on the closing body, when it assumes its release position, demolished at the transition of the closing body in its blocking position from the closing body or from the first passage become. The one valve seat forming passage is thus cleaned as well as the closing body of dirt. This increases the sealing effect of the closing body in its blocking position.

Preferably, the closing body is aligned transversely to the longitudinal axis of the housing of the water discharge device.

Conveniently, the closing body is arranged on a valve tappet, which passes through the first passage. The valve tappet can be manually displaced, so that water can be supplied depending on the position of the valve tappet of the at least one controllable nozzle which is arranged on the outlet chamber.

It can be provided that the valve tappet passes through the longitudinal channel, via which the nozzles are in fluid communication with the water inlet.

In a preferred embodiment, the valve stem is rigidly connected to at least one handle arranged laterally on the housing. In particular, it can be provided that the valve stem carries at least one end of a handle. This can for example be locked with the valve stem.

It is advantageous if the at least one outlet chamber has, on the side opposite the first passage, a second passage which is in alignment with the first passage and against which the valve tappet rests sealingly in its locking position and in its release position. Conveniently, the valve stem carries in the region of the second passage a sealing element, which rests sealingly at the transition of the valve stem from its blocking position to its release position and the transition of the valve stem from the release position to the blocking position on the second passage. The second passage thus forms a guide for the valve stem. This makes it easier to align the valve stem in its blocking position such that the valve body arranged on the closing body the flow connection between the longitudinal channel and the at least one controllable nozzle which is connected to the respective outlet chamber, reliably interrupts.

The valve tappet passes through the second passage in an advantageous embodiment. It can protrude from the second passage both in the blocking position and in the release position on the side facing away from the first passage side of the second passage.

It is particularly favorable when the valve tappet is rigidly connected on the side of the second passage facing away from the first passage to a handle arranged laterally on the housing of the water discharge device. By means of the handle, the valve stem can be moved by hand. The handle can be fixed directly on the valve stem. In particular, it can be provided that the handle can be latched to the valve tappet.

In order to improve the guidance of the valve tappet, it is provided in an advantageous embodiment of the invention that the housing of the water discharge device forms at least one guide member against which the valve tappet rests in a sliding manner. The guide member may be configured, for example, as a guide sleeve.

Preferably, the at least one guide member is integrally connected to the housing. In particular, it can be provided that the housing and the at least one guide member are formed as an integrally formed plastic molded part.

Preferably, the housing of the water discharge device on two aligned mutually aligned guide members on which the valve stem is slidably applied both in its blocking position and in its release position.

As already explained, the water supply for the respective outlet chamber can be interrupted by the closing body arranged on the valve tappet. It is favorable if at least one outlet chamber is connected to at least two jointly controllable nozzles. The control of these at least two nozzles is effected by the closing body arranged on the first passage of the outlet chamber. If the closing body assumes its blocking position, the water supply to the outlet chamber and thus to the at least two controllable nozzles connected to the outlet chamber is interrupted. If the closing body assumes its release position, the at least two nozzles, which are connected to the outlet chamber and can be controlled in common, are in fluid communication with the longitudinal channel and can be supplied with water.

It can also be provided that at least one outlet chamber is connected to a multiplicity of nozzles, which can be controlled together by means of the closing body arranged on the first passage of this outlet chamber.

Preferably, the water discharge device of the sprinkling device has a plurality of outlet chambers, which are each connected to at least one controllable nozzle. Each of these outlet chambers comprises a first passage, on which a displaceable closing body is arranged. The user can thus by selecting the positions of the various closing body select which nozzles should be supplied with water and which nozzles should be shut off. He can thereby adjust the size of a surface to be wetted individually.

The housing of the water discharge device is configured in an advantageous embodiment of the invention as a tubular hollow body which defines the longitudinal channel. The wall of the housing thus limits the longitudinal channel. The housing is filled during operation of the sprinkler with water that can flow through the water inlet into the housing of the water dispenser.

Conveniently, a chamber body is arranged in the longitudinal channel, which defines the at least one outlet chambers. The chamber body thus divides the interior of the housing into the longitudinal channel and the at least one outlet chamber. Some of the nozzles can be supplied directly from the longitudinal channel with water, other nozzles are connected via an outlet chamber with the longitudinal channel, which is defined by the chamber body and which is in flow communication via a first passage with the longitudinal channel.

The chamber body extends in an advantageous embodiment of the invention over the entire length of the housing of the water discharge device.

It can be provided that the chamber body has a base part forming the bottom and the side walls of the at least one outlet chamber and a lid part forming the ceiling wall of the at least one outlet chamber, which is placed on the base part.

Conveniently, the cover part of the chamber body carries the nozzles of the sprinkler. This facilitates the installation of the same.

In a preferred embodiment of the invention, the lid part of the chamber body and the nozzles of the sprinkler are designed as a one-piece plastic molding. The nozzles are on the top side from the lid part, which is placed on the base part of the chamber body.

Preferably, the one-piece plastic molding, which forms the lid part and the nozzle, elastic. The plastic molding may be made of an elastically deformable plastic material.

The one-piece molded plastic part forming the cover part and the nozzles is pressed in a preferred embodiment between the base part of the chamber body and a housing cover of the housing of the water discharge device. Additional fixation can be omitted. In addition, such a configuration allows a sealing contact of the cover part of the chamber body on the inside of the housing cover of the water discharge device, so that additional sealing elements can be omitted. In particular, in the case of an elastically deformable design of the plastic molded part, this can be pressed in a simple manner between the base part and the housing cover. The pressure required to press in the plastic molded part is exerted in an advantageous embodiment of the base part of the chamber body, for example, of at least an obliquely extending rib, which is integrally formed on the housing of the water discharge device, is pressed upward in the direction of the housing cover.

It is advantageous if the chamber body defines at least one outlet chamber in a first end region facing the water inlet and in a second end region remote from the water inlet, wherein the two end regions are rigidly connected to one another via an outlet chamber-free intermediate region. One or more controllable nozzles may each be connected to the discharge chambers arranged at the end, and further nozzles of the water discharge device may be positioned in the two-region region of the chamber body. In this intermediate region, the nozzles of the irrigation device are directly in fluid communication with the longitudinal channel. These nozzles can not be turned off individually, whereas the nozzles arranged in the end regions are in fluid communication with the longitudinal channel via the respective outlet chambers and the water supply to these nozzles can be regulated individually by means of the closing bodies respectively arranged on the first passage of the outlet chambers.

The intermediate region of the chamber body is designed in an advantageous embodiment as a support profile. It can be designed in cross section, for example, I-shaped or T-shaped. This makes it possible to give the chamber body a very high mechanical stability. The support profile forms between the two end regions of the chamber body, in each of which at least one outlet chamber is arranged, a web-like connection part.

As already explained, the chamber body is surrounded by the housing of the water discharge device, wherein the housing defines the longitudinal channel. It is favorable if the longitudinal channel extends at least along a first and a second longitudinal side of the chamber body. The chamber body is thus flowed around within the housing, at least in the region of its longitudinal sides of water. The first passages of the outlet chambers can be arranged in the region of one longitudinal side of the chamber body, so that water can be supplied to the outlet chambers via the laterally arranged first passages if the respective closing body assumes its release position. If the closing body is displaced into its blocking position, then the respective first passage is closed and thus the water supply to the at least one nozzle, which is connected to this outlet chamber, interrupted.

Shown schematically in the drawing is a sprinkler device, generally designated by the reference numeral 4, which is used, for example, in the form of a lawn sprinkler, with the aid of which a lawn can be irrigated. In the same way, of course, a different kind of area can be irrigated, for example, a vegetable patch.

The sprinkling device 4 has a carrier device 5, on which a drive device 6 is held, which is coupled to a pivotably mounted water dispenser 10. The drive device 6 is designed in the usual way as a hydraulic motor, which causes the water discharge device 10 to pivot. The drive device 6 and the water discharge device 10 are aligned with each other. On the side facing away from the water discharge device 10, the drive device 6 has a connection nipple 7 which is connected to a water supply line, for example to a garden hose (not shown in the drawing) can be connected. About the connection nipple 7 of the sprinkler 4 water can be supplied.

The water dispenser 10 is in the FIGS. 2 to 8 shown in detail. It has an elongated housing 12, which has a nozzle-shaped water inlet 14, which protrudes from a first end face 16 of the housing 12 from this and projects into the drive device 6 in the mounted state. A second end face 17 of the housing 12 facing away from the first end face 16 carries a bearing stub 18. The water inlet 14 is in fluid communication with the connecting nipple 7 via the drive device 6. In addition, the water inlet 14 serves in the same way as the bearing stub 18 of the pivotable mounting of the water dispenser 10. With the aid of the drive means 6, the water dispenser 10 can be pivoted about the longitudinal axis 20 of the housing 12 alternately.

The housing 12 has a housing cover 22 with a plurality of openings 23, which are each penetrated by a nozzle 25. The nozzles 25 are arranged on the housing cover 22 in the form of two rows of nozzles aligned parallel to one another, wherein they are each arranged offset in the direction of the longitudinal axis 20.

In addition to the housing cover 22, the housing 12 of the water discharge device 10 has a housing bottom 27 which is connected to the housing cover 22 via a first housing longitudinal wall 28 and a second housing longitudinal wall 29. In the longitudinal direction, the housing 12 is at the first end face 16 of a first end wall 31 and on the second end face 17 of limited to a second end wall 32. The housing 12 is thus designed as a hollow body whose interior is accessible via the water inlet 14 and defines a longitudinal channel 34 which extends from the first end wall 31 to the second end wall 32.

The housing 12 surrounds a particular in the FIGS. 4 to 7 illustrated chamber body 36 which has a designed as a plastic molding base part 37 and a cover part 38 which is mounted on the base part 37. In a first end region, which faces the water inlet 14, the chamber body 36 defines three identically configured outlet chambers 41, 42, 43 arranged in series next to one another along the longitudinal axis 20, and defines in its second end region, which faces away from the water inlet 14 Chamber body 36 three further, identically designed and arranged along the longitudinal axis 20 in series juxtaposed outlet chambers 44, 45 and 46. The outlet chambers 41 to 46 each have a bottom wall 48 and a first side wall 49 and a parallel to the first side wall 49 extending second side wall 50 , In the longitudinal direction, the outlet chambers 41 to 46 bounded by the two side walls 49, 50 interconnecting transverse to the longitudinal axis 20 transverse walls 51. The bottom wall 48 as well as the side walls 49 and 50 and the transverse walls 51 are defined by the base portion 37 of the chamber body 36. In an intermediate region 53 between the outlet chambers 41, 42 and 43 on the one hand and the outlet chambers 44, 45 and 46 on the other hand, the base part 37 forms a Auslasskammerfreies support profile 55 which is configured in cross-section substantially T-shaped, wherein a crossbar 56 of the support profile 55 a Continuation of the bottom wall 48 of the outlet chambers 41 to 46 forms and a longitudinal beam 57 forms a connecting web extending between the discharge chamber 43 and the discharge chamber 44.

The cover part 38 rests on the base part 37 and forms a top wall 59 of the outlet chambers 41 to 46, wherein the cover part 38 extends not only in the region of the outlet chambers 41 to 46 but also via the intermediate region 53. It forms a support for the nozzles 25, which are formed on the lid part 38. Together with the nozzles 25, the cover part 38 forms a one-piece plastic molded part, which is made of an elastic plastic material and pressed between the base part 37 and the housing cover 22.

The nozzles 25 each have a nozzle channel 61. In the amount of the outlet chambers 41 to 46 respectively open the nozzle channels 61 of two adjacent nozzles 25 in a discharge chamber 41, 42, 43, 44, 45 and 46, whereas the nozzle channels 61 held at the level of the intermediate portion 43 on the cover member 38 nozzles 25 to both Pages of the support profile 55 directly into the longitudinal channel 34 defined by the housing 12.

The outlet chambers 41 to 46 are in each case in flow communication via the first passage 64, which penetrates the respective first side wall 49, with the first longitudinal passage 34 extending on the outside along the side walls 49 and 50 and the bottom wall 48. In alignment with the first passage 64, the respective second side wall 50 of the outlet chambers 41 to 46 is penetrated by a second passage 65. Flushing to the passages 64 and 65 is to the first housing longitudinal wall 28 and to the second housing longitudinal wall 29 each formed a guide member in the form of a first guide sleeve 69 and a second guide sleeve 70.

Each outlet chamber 41 to 46 is associated with a valve stem 72, which passes through the respective outlet chamber 41, 42, 43, 44, 45 and 46 transversely to the longitudinal axis 20, wherein it at the level of the first passage 64, a first closing body in the form of a first sealing ring 74th carries, which is arranged in an annular groove 75 of the valve stem 72, and at the level of the second passage 65 of the valve stem 72 carries a second closing body in the form of a second sealing ring 77, which is arranged in an annular groove 78 of the valve stem 72. With a first end portion 80, the valve stem 72 extends through the first guide sleeve 69 of the housing 12, and with a second end portion 82, the valve stem 72 extends through the second guide sleeve 70 of the housing 12, wherein in the first end portion 80, a third sealing ring 84 and in the second end region 82 carries a fourth sealing ring 85. The first end portion 80 of the Ventilstossis 72 receives a first handle in the form of a first push button 87 and the second end portion 82 receives a second handle in the form of a second push button 88 which are respectively latched to the valve stem 72 and the outside of the first housing longitudinal wall 28th or are arranged on the second housing longitudinal wall 29. They each have an annular space 90 which receives the first guide sleeve 69 and the second guide sleeve 70 when the valve stem 72 is displaced.

The flow connection between the longitudinal channel 34 and the nozzles 25 connected to the respective outlet chamber 41 to 46 can be selectively released or shut off by means of the valve plungers 72 which pass through an outlet chamber 41 to 46 in each case. For this dives in the in FIG. 4 shown Locking position of the valve stem 72, the first sealing ring 74 in the first passage 64, which forms a valve seat for the first sealing ring 74. In the blocking position of the valve stem 72 thus the first sealing ring 74 is sealingly against the first passage 64 and the supply of water from the longitudinal channel 34 into the respective outlet chamber 41 to 46 is interrupted.

The valve stem 72, starting from its in FIG. 4 shown blocking position transversely to the longitudinal axis 20 and thus also perpendicular to the defined by the edge 92 of the first passage 64 cross-sectional area so far from the first passage 64 in the second passage 65 facing away from the direction to the outside until the first sealing ring 74, the first passage 64 releases , This release position of the valve stem 72 is the example of the outlet chambers 41 and 43 in particular FIG. 5 shown. It is clear that the respective outlet chamber via the first passage 64 is in flow communication with the longitudinal channel 34, provided that the valve stem 72 assumes its release position. The transition from the release position into the blocking position takes place in that the valve stem 72 is displaced transversely to the longitudinal axis 20, wherein the first sealing ring 74 increasingly approaches the first passage 64 and finally immersed in this, in order to abut sealingly against its wall. As the first sealing ring 74 approaches the first passage 64, the flow cross-section available to the water flowing into the respective outlet chamber 41 to 46 in the region of the first passage 64 is increasingly reduced. This has the consequence that the water in the region between the first sealing ring 74 and the first passage 64 at the transition of the valve stem from its release position in its blocking position has a high flow velocity. This in turn causes a cleaning of both the surface of the As a result, the sealing effect of the first sealing ring 74 is maintained even after repeated opening and closing movements of the valve stem 72.

The second sealing ring 77, which is held at the level of the second passage 65 on the valve stem 72, takes both in the FIG. 4 illustrated blocking position and in the example in FIG. 5 illustrated release position of the valve stem 72 a position within the second passage 65, so that it is reliably sealed regardless of the position of the valve stem 72. For this purpose, the second passage 74 has a significantly greater extent in the direction of displacement of the valve tappet 72 than the first passage 64.

To move the respective valve stem 72 of the outlet chambers 41 to 46, the user can actuate the first push button 87 or the second push button 88, so that the valve stem 72 is acted upon with a pushing force in the direction of its blocking position or in the direction of its release position. Since the push buttons 87 and 88 are arranged on the outside of the housing 12, the user can easily recognize on the basis of the position of the push buttons 87 and 88 of each valve stem 72, whether the respective valve stem 72 assumes its blocking position or its release position.

By operating the valve tappet 72 by means of the push buttons 87 and 88, the user can thus each two nozzles 25 control together, that is, he can shut off or release them together.

While the respective nozzles 25, which are in fluid communication with the longitudinal channel 34 via an outlet chamber 41 to 46, can be controlled by the user by actuating the pushbuttons 87 and 88, the nozzles 25 arranged at the level of the intermediate region 53 are directly connected to the longitudinal channel 34 which means the height of the intermediate portion 53 arranged nozzles 25 can not be controlled by the user. As soon as water is supplied to the irrigation device 4 via the connection nipple 7, it is discharged from the nozzles 25 arranged in the intermediate region 53, whereas the water discharge of the controllable nozzles arranged at the outlet chambers 41 to 46 can be regulated by the user.
