- the circulating pump disclosed there has one outside the pump housing arranged actuator to by means of a non-positive connection between the actuator and the actuator of the valve device Flow regulation by making the effective cross section, the the suction opening assigned to the pump impeller is variable.
- the overall arrangement of the pump and Actuator achieved a very large design and also special Sealing measures are to be taken over the outside Actuator to move the inner valve actuator in front of the intake opening.
- the object of the invention is a structurally simplified circulation pump to provide a valve device for changing the cross section of a Has suction opening, in particular to completely close the suction opening close.
- valve device and a control device for actuating the valve device within of the pump housing are provided.
- At least one temperature sensor or one temperature sensitive element may be provided within the pump if a valve setting e.g. depending on the fluid and / or engine temperature should be done.
- the construction according to the invention is very small because the control device realized in the engine compartment of the engine of a circulation pump can be.
- valve device and the control device on each other opposite sides of the drive motor arranged in the circulation pump are.
- the valve device can preferably directly in front of the Pump impeller are arranged, whereas the control device on the side of the drive motor opposite the pump impeller can be arranged. At most, this results in a minor one Extension of the overall design combined with a valve device Circulation pump, the diameter or the width more conventional Circulation pumps can be retained.
- valve actuator of the valve device is coaxial is movable to the motor shaft.
- Valve actuator which is designed, for example, as a valve disk, in Direction of the longitudinal axis of the motor shaft on the suction mouth of the impeller and / or a suction opening of the pump impeller or one in front of it Arranged valve seat can be moved or moved away from it in order to to vary the effective cross section of the suction mouth / suction opening, if necessary to close or fully open.
- An actuation of the valve actuator of the valve device can Design can be achieved particularly preferably in that a Actuating element for moving the valve actuator is provided, which away from the control device by a hollow motor shaft extends.
- the actuating element can be operated by means of the control device operated depending on temperature i.e. be moved, the Actuation through the hollow motor shaft into a movement of the Valve actuator implements.
- the effective suction opening in its cross section be reduced or enlarged or closed or opened.
- temperatures at any point of the Pump or in the circulating fluid can be detected and the control device these temperatures are supplied as a measured variable.
- actuating element as one Rod is formed which e.g. at one end carries the valve actuator or whose end for actuating the valve device, in particular the Valve actuator is provided.
- This can be done by an axial displacement of this Rod in the direction of the motor shaft, the valve actuator, in particular Valve disc, relative to the suction mouth of the impeller or one in front of it arranged suction opening can be positioned.
- the linear displacement of the formed as a rod actuator in the direction of the motor shaft achieved by any mechanics within the control device become.
- a mechanical and / or electrical actuator is provided is to operate the rod.
- the control device is as fluid-filled expansion vessel formed.
- a fluid-filled Expansion vessel is characterized in that it is a fluid, for example a gas, wax or liquid that contains a high Has expansion coefficients, so that at different Temperatures vary widely within the Expansion tank adjust what a movement of a Pressure equalization mechanism causes the movement of which e.g. as a rod trained actuator transmits.
- This can be a common one mechanical training can be realized as they come from thermostatic valves is known to move the adjusting pin.
- control device in particular the said Expansion vessel be arranged coaxially within the stator and continue the rotor can be arranged around the stator.
- a regulation of the flow rate or the shut-off of the delivery fluid e.g. at falling temperatures or temperatures below one Operating temperature in the engine compartment is particularly useful if at standing circulation pump a circulation by a heat consumer by the respective circulation pump is supplied with fluid to be prevented. This can save a considerable amount of energy.
- An essential application of such e.g. temperature-controlled Circulation pump is, for example, the use as a decentralized heating pump where a circulating pump is assigned to each radiator, the one there Usually arranged thermostatic valve replaced. With this application it is sensible, a possible after switching off the motor of the circulation pump To completely prevent the flow of fluid through this pump by creating a Opening, e.g. the suction opening in the fluid path of the pump is closed.
- this is advantageously achieved achieved that when the temperature in the engine compartment falls below the operating temperature e.g. automatically due to the cooling of the fluid in the expansion tank Displacement of the actuating element designed as a rod in the direction the valve actuator completes the intake opening of the circulation pump closes.
- the pumping of fluid through a radiator is intended again an opening, e.g. the suction opening in the fluid path of the pump is opened.
- the engine the circulation pump is energized and thereby generates waste heat, which leads to a Expansion of the fluid in the expansion tank leads, which automatically Valve actuator is pushed out of the valve seat and the suction opening releases.
- This pushing out is preferably against one in the valve seat inward force, so with falling temperatures and yourself contracting expansion fluid automatically into the valve actuator Valve seat is pressed.
- a heat generator within the expansion vessel is arranged with the specific heating of the fluid in the expansion vessel can be done.
- a heat generator can be supplied with current Coil or as a resistor to artificially initiated heating to reach the fluid, causing the valve actuator to come out of the valve seat is pushed out. In general, this way not only temperature-dependent control / regulation the valve device can be operated.
- valve actuator can also be provided to be specifically adjusted by the control device, in particular only in two End positions in which the valve device is either open or closed.
- the Valve device comprises a two-way locking mechanism, in particular that Valve actuator is connected to a two-way locking mechanism.
- a two-way locking mechanism is understood to mean a mechanism that with an always identical type of actuation movement, alternating two goes through various work paths, and so the associated valve actuator alternating in one or the other end position, i.e. the open or closed position transferred.
- valve actuator is replaced by the Two-way locking mechanism released from the first locking position and into one transferred second locking position, which corresponds to the closed position. Also in this position requires no further actuation to hold the valve.
- valve device When activated again, the valve device is opened again Position transferred and so on.
- the two-way residual mechanics as they do from Ballpoint pen mechanisms are known to control the control device only required to change valve positions, however no energy is required to hold in one of the positions. So in Embodiments of the expansion vessel by heating (e.g. by energizing a coil in the expansion tank) the valve device from one position of the valve actuator can be transferred to another.
- valve actuator is permanently acted upon by a force in a direction that e.g. is generated by a spring. This reliably ensures that Valve actuator securely in one of the two upon actuation of the actuating element possible end positions is transferred.
- the two-way locking mechanism can be implemented in a known manner Toggle jumps, stepping gears, cams running on inclined surfaces, in Control grooves running cams, gears etc.

- the rotor 4 By energizing the stator 3, the rotor 4 is set in rotation, whereby equally that with the rotor 4 via one in the two bearings 6 Hollow shaft 7 drives the impeller 5.
- the impeller 5 has a suction mouth 8 which is directly connected to a suction opening 9 in the inner housing area of the circulation pump is opposite. Through the rotation of the impeller 5 is thus from the suction chamber 10 in the direction of the illustrated Arrow 11 sucked fluid and transported into the pressure chamber 12, from where it is here Pressure pipe, not shown, of the circulating pump is supplied.
- valve device 13 essentially comprises a plate shape trained valve actuator 15, which in shape to one to the Suction opening 9 adjoining valve seat 16 is adapted.
- valve plate 5 is arranged at one end of an actuating rod 17 which itself from the suction chamber 10 through the suction opening 9, the impeller 10 and the Hollow shaft 7 of the drive motor extends into the control device 14 and can be moved in the axial direction by means of this.
- the displacement of the valve plate 15 takes place when the temperature rises Engine compartment against a force in the present case by a spring 18 the valve plate 15 is applied in order to direct it into the valve seat 16 press.
- the spring 18 is both on the valve plate 15 and on one mounted on the housing-side region of the inner wall of the suction chamber 10.
- the control device 14 For simple actuation of the valve actuator 15 by means of the Actuating rod 17 is the control device 14 in the present case Form of an expansion vessel 19 which is completely inside of the pump housing in the engine compartment. Within the Expansion vessel 19 is a fluid 20, such as a gas or a liquid which has a high coefficient of expansion.
- FIG. 2 shows a particularly small-sized circulation pump according to the invention 1.

- This distance is selected such that the stator 3 around the expansion vessel 19 of the motor of the circulation pump 1 can be arranged.
- This stator can with With reference to Figure 2 inserted into the can from the right during assembly become.
- the expansion tank is accordingly 19th as a special version of the control device coaxially within the Stator 3 arranged.
- A extends from the expansion vessel 19 through the hollow shaft 7 Actuating rod 17 at the other end of which a valve plate 15 is attached.
- the Valve plate 15 is connected via a spring 18, which in this embodiment is a tension spring 18 is drawn into the valve seat 16 and when the fluid expands in the expansion vessel 19 via the compressed bellows 21 and the Actuating rod 17 pressed out of the valve seat 16 against the spring force.
- the fluid path of the pumped fluids are formed by an inner pump region 23 which can be inserted into the housing 2 on the left after the impeller 5 was positioned on the hollow shaft 7.

- the two-way locking can be carried out in any manner.
- the exemplary embodiment shown here should not be interpreted as restrictive. It is particularly advantageous in all of the designs shown that no special sealing measures are required, since the entire valve device and also the regulating / control device are arranged entirely within the housing of the circulation pump, the expansion vessel in particular being able to adjoin the can bottom of the motor. It can be provided here that the expansion vessel and containment shell or split tube and / or hollow shaft are formed in one piece in order to avoid additional seals.
