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.
