ABSTRACT:
Hydrostatic unit is disclosed of the kind having axial pistons and a variable stroke volume, in which a distributor body is rotatable about an axis inclined relative to the axis of a driving shaft and rotatably carries a cylinder block so that the axis of rotation of the cylinder block passes through the point of intersection of the axes of the distributor body and the driving shaft, the improvement consisting in that a phase-adjusting plate is inserted between the cylinder block and the distributor body and has ports equal to the distribution ports of the distributor body, it being possible to rotate the plate about the axis of the cylinder block so as to allow for the shifts of the dead centers of the pumping pistons relative to the distribution ports of the distributor body.
