- Erfindungschertiich is that at the opposite end of the drive member 5 of the drive shaft 1, a working chamber 12 is disposed, into which the through hole 7 opens, between the through hole 7 and arranged in this adjustment device 2, an annular space 11 is arranged, wherein at the Spring system 9 opposite end of the adjusting device 2 is arranged with the working chamber 12 in operative connection working piston 13 such that at pressure buildup in the working chamber 12, the adjusting device 2 against the spring force of the return spring 10 in the through hole 7 can be moved variably.
- a pumping piston 18 is arranged with a piston passage bore 19, which opens into a housing 3 arranged in the pressure channel 17.
- an eccentric bushing 21 is arranged, in which one hand with the Working chamber 6 connected suction kidney 22 and on the other hand on the circumference of the eccentric bushing 21 opposite a pressure kidney 23 is arranged, wherein the pressure kidney 23 has a arranged in the eccentric bushing 21 transfer hole 24, which opens into a further and in the drive shaft 1 adjacently arranged transfer hole 24 and so the pressure kidney 23 connects directly to the annulus 11.
- a cylinder ring 25 is rotatably arranged with a piston bore 26 for the pump piston 18 so that in circumferential eccentric bushing 27 of the pump piston 18 in the piston bore 26 of the cylinder ring 25 "works", ie oscillating vertically moved up and down and pumping with closed solenoid valve 29 via the suction kidney 22 in the working space 6 medium located in the pressure kidney 23, which is conveyed from there via the transfer bores 24 and the annular space 11 in the working chamber 12.
- a valve seat 27 is arranged, in the one hand, the pressure channel 17 and on the other hand connected to the working space 6 return line 28 opens, wherein in the valve seat 27 between the pressure channel 17 and the return line 28, a solenoid valve 29 is arranged.
- solenoid valve 29 When rotating the drive shaft 1 and closed solenoid valve 29 causes the present invention in the piston bore 26 of the cylinder ring 25 oscillating vertically up and down moving pump piston 18 that pumped in the working space 6 medium via the suction kidney 22 into the pressure kidney 23, and from there via the Transfer bores 24 and the annular space 11 is conveyed into the working chamber 12.
- FIG. 2 now shows one of the possible structural embodiments of the solution according to the invention in the design of a coolant pump for motor vehicles, with a control slide 35 displaceable by means of an adjusting device 2, which serves to vary the "effective" blade width of the impeller.
- the bearing in the housing 3 in a bearing 4, driven by a drive element 5, in a pressurized medium filled working space 6 projecting drive shaft 1, in which a Versteilvorraum 2 receiving through hole 7 is arranged, is particularly characterized by the fact that working space side in the housing 3 rotatably arranged with a working space 6 towards the blind hole 14 provided pivot cylinder 15 is arranged, whose open bore end 16 opens into a pressure channel 17, wherein rotatably on the pivot cylinder 15 is a pump piston
- the transfer region is formed in the suction kidney 22, which is open on one side wall, as an annular channel 30, which is directed outward, i.e. outwards. towards the working space 6, adjacent an annular gap filter 31 is arranged, so that in this area a transfer of cooling medium from the pump interior 14 into the annular channel 30 is possible, wherein the adjustment of the filter gap of the annular gap filter 31, the penetration of undesirable particle sizes of chips or grains of sand is prevented.
- the drive shaft 1 is set in a rotating movement, so at the same time rotatably mounted on the drive shaft 1 eccentric bushing 21, which on the one hand with a side facing the diegelrad kiten side open suction kidney 22 and on the other hand provided with a through hole 7 in the drive shaft 1 open towards pressure kidney 23, set in a rotational movement.

- the inventive arrangement ensures over the entire speed and temperature range in all the embodiments presented an active and reliable control of the longitudinal displacement of the adjusting device 2 with very low drive power.
- the present solution is suitable even for high speed applications.
- the solution according to the invention is very small and uses the available space optimally, is very compact and works very robust and reliable.
- the present solution is easy to manufacture and assembly technology and inexpensive to produce and always ensures high reliability. Even under very unfavorable thermal boundary conditions, such as in the vicinity of a turbocharger in a motor vehicle, and at the same time very limited installation space ensures the solution according to the invention due to the arrangement of a medium simultaneously cooled by the pump solenoid valve 29 optimum cooling with minimal volume and high reliability. Even if the control fails, a "fail-safe" function as described below can be realized by means of the solution according to the invention.
- the solenoid valve 29 opens, the pressure in the pressure channel 17 and in the working chamber 12 falls off, and it takes place, in the design of the invention shown in Figure 2, a spring-loaded “retracting" the control slide 7 in the rear working position, for example the "Emergency operation", ie a "fail-safe” position.
