Abstract: The present invention relates to a drive mechanism for a pump (10) implemented by means of a drive motor (20), the rotational speed and torque of which are influenced by a frequency converter (30). The frequency converter (30) is arranged on a heat dissipator (40) confining a flow of the pressure liquid guided to the pump (10). It is advantageous to also arrange the drive motor (20) inside the said heat dissipator (40), for this makes it possible to perform intense forced air cooling of a pump-drive motor system without the necessity of an additional cooling liquid. The drive motor (20) preferably has a central arrangement inside a tubular heat dissipator and is exposed to the pressure liquid over its entire circumference. Baffles or offset connecting sleeves allow for uniform flow through the entire heat dissipator (40).

Abstract: A constructional unit comprising a hydraulic machine having a drive or driven shaft and of a support by which the hydraulic machine is held with the interposition of material which deadens solid-conducted noise. Low noise emission of the hydraulic machine is obtained in the manner that the support extends over the hydraulic machine in particular in the direction towards the shaft and that the hydraulic machine is supported on the support via material which deadens solid-conducted noise, present between its outer wall surface and the support. In this way the noise emission can be reduced in a simple manner.

Abstract: A control valve for a variable displacement pump is improved so that the levelling of the pressure fluctuations of the pump is better and quicker. For this purpose an additional control piston portion on the control piston of the control valve is used. Corresponding to the deflection of the control piston the constriction cross-section set by the control piston portion between the supply connected to the pump pressure line and a passage leading to the control space of the variable pump is varied so that the pressure rise in the control space of the pump and also the pressure drop is accelerated.
