The invention concerns a hydraulic swash block positioning system for positioning a swash block to set a variable displacement, the hydraulic device comprising a rotor with pistons and piston chambers, the positioning system comprising between the housing and the swash block a positioning cylinder with a positioning piston forming a positioning chamber for setting an average value of the swash block position and a control valve connecting the high oil pressure source with the positioning chamber through a feeding line. In accordance with the invention the feeding line is connected to an oil container that has a variable container volume and the oil container has means for adjusting the variable container volume synchronously with the changes in the number of piston chambers connected to the high oil pressure source. |
