  • This is pump shaft side in the working housing 12 adjacent to a pressure chamber 15 which opens via a pressure channel 16 in an annular channel 17, which in one of the seal holder 10 on the impeller side opposite in the pump housing 1 arranged sleeve receptacle 18, rotationally symmetrical to the axis of rotation of the pump shaft 4 is incorporated.
  • the housing of the actuator 13 and the working sleeve 14 are made of one piece.
  • annular piston working sleeve 19 is arranged with a sealing web 20 and a bottom 21 in which the pump shaft 4 rotates freely.
  • flow openings 23 are arranged to the annular channel 18 near the bottom.
  • the inner wall 24 of the annular piston working sleeve 19 is fastened in a force-locking manner to a position securing sleeve 25 with a rigidly arranged wall plate 26.
  • a profile sealing ring 27th is arranged. This is on the wing wheel side positively connected to a provided with a web system 28 annular piston 29.
  • the rear wall 7 of the valve slide is arranged in a form-fitting manner in the end region of the wing wheel.
  • the restoring spring 6 is arranged between the wall plate 26 and the rear wall 7 of the valve slide resting against the annular piston 29.
  • a bypass seal 30 is arranged with an elastomer sealing lip, which prevents a pressure build-up between the wall plate 26 and the rear wall 7 of the valve spool with the resulting bypass leakage at "closed" valve spool.
  • the primary seal is ensured between the end face of the outer cylinder 9 and the associated counter surface in the spiral housing.
  • the function of "zero leakage" (zero promotion) can be optimally realized with minimal power consumption to functionally reliable and reliable to set the coolant flow during the warm-up phase of the engine completely shut down if necessary.
  • a working chamber 31 adjacent to the pressure chamber 15 is arranged in the working sleeve 14, wherein an outlet valve membrane 32 provided with a perforated diaphragm is arranged between the working chamber 31 and the pressure chamber 15.

  • an inlet opening 51 leading into the area of the spring chamber 48 and in the armature 45, in the anchor stop 50 and in the housing of the actuator 13 each adjacent / merging outflow openings 52 are arranged.
  • the rod seal 39 separates the area of the actuator leading to the coolant from an area filled with air (“dry"), the inflow opening 51 and outflow openings 52 allow free gas exchange with the environment, thereby providing a low-friction translational movement of the armature 45 in the area the solenoid 46 is ensured.
  • the inventive method for influencing the flow rate of the described in the, in the FIG. 1 illustrated controllable coolant pump is characterized by the fact that by varying the current intensity and / or the duration of the current applied to the solenoid current pulses in the magnetic field 46 acting on the magnet armature 45 force is varied, so that in conjunction with the action of the compression spring 49 on the Magnetic armature 45, the frequency and / or the stroke (the amplitude) of the oscillations of the working piston defined is / are varied so that the working piston 34 by means of the arranged at the opposite end of the piston rod 33 in the magnetic field of the magnetic coil 46 magnet armature 45 repeatedly (periodically), and is placed in defined translational oscillations.
  • This magnetic actuation causes in conjunction with the arrangement according to the invention in many small "part strokes” stocky “pump promotion", which then due to the special arrangement according to the invention has a displacement of the valve spool with its outer cylinder 9 and arranged on these assemblies.

  • an outlet valve membrane 32 is provided which is provided with a pinhole. If now the working piston 34 (as described above) vibrated, so is sucked from the via the inlet bore 42 to the pump interior 8 annular space 43 coolant through the filter element 44 through the inflow openings 41 into the inflow 40 in, and at the same time through the Through holes 36 of the working piston 34 in the working piston arranged on the annular groove 35 and from there Pressed over the provided with a pinhole inlet valve diaphragm 37 into the working space 31, and then introduced from there via the provided with a pinhole exhaust valve membrane 32 into the pressure chamber 15.
  • the solution of the present invention which can be easily standardized and manufactured cost-effectively, ensures high pump and motor efficiency with a minimum use of energy (which is less than 5 W).
  • the "neutral" construction according to the invention makes it possible for the actuator 13 according to the invention to be used as a standardized component in various water pumps.
  • the actuating unit according to the invention which due to the superposition of a "pumped flow” with a “leakage flow” a space-optimized, compact, manufacturing and assembly technically simple as well as very cost-effective and very robust solution, thus allowing a reliable operation of the valve spool even with very strong limited installation space (for the actuator of the coolant pump).
  • Another advantage of the solution according to the invention consists in the fact that the filter element 44 does not have to be exchanged during the entire service life, since only very small volume flows (and these always only “down” and then back again) are exchanged via the filter element 44 become.
