<p>A hydraulic pump comprising a mantle as pump body, a drive (1) shaft directed into the pump, a cylinder block (2) arranged around the shaft and rotated by said shaft, for instance by means of a longitudinal groove assembly (14), when the cylinder block is movable lengthways on said shaft. The length of the moment-transmitting groove assembly (14) placed between shaft (1) and cylinder block (2) is restricted axially so that the moment-transmitting capacity of the assembly can be released in shifting the cylinder block (2) axially till the cylinder block groove assembly becomes disengaged from shaft (1) groove assembly (14).</p> |
