ARRANGEMENT FOR HYDRAULIC ECCENTRIC ADJUSTMENT TO SET A PREDEFINED DISPLACEMENT FOR A HYDROSTATIC MOTOR

摘要

The invention relates to an arrangement for hydraulic eccentric adjustment to set a predefined displacement for a hydraulic motor, particularly a radial piston motor (1), comprising an adjustment device that can be loaded with a pressure medium in order to position an eccentric element (2) through a shuttle valve (5), wherein at least one actuating piston (19) of an adjustment cylinder (3) which can be loaded on both sides is provided as the adjustment device. One pressure chamber (7) of said adjustment cylinder is connected to a first supply line (9) to set a smaller displacement, and the other pressure chamber (8) of said adjustment cylinder is connected to a second supply line (10) to set a higher pressure volume, wherein the two supply lines (9, 10) are connected to each other through a connection line (11).
