Hydraulic arrangement, in particular for stabilising and regulating the level of a vehicle

摘要

Hydraulic arrangement, in particular for stabilising and regulating the level of a vehicle, with a cylinder/piston unit (5) which has a pressure space (7, 7') which can be connected to a pressure line (4) via a directional control valve (10). The pressure space (7, 7') loads an axially displaceable working piston (6) at the end face. The working piston (6) is connected to a piston rod projecting axially outwards. Leading into a collecting tank (3) is a return line (8) which can be connected to the pressure space (7, 7') via the directional control valve (10). Arranged in the pressure line (4) is a variable-delivery pump (1) which is connected to the collecting tank (3) via an intake line (2). A hydraulic accumulator (16) supplied with constant pressure by the variable-delivery pump (1) is arranged in the pressure line (4) between the directional control valve (10) and the variable-delivery pump (1), and a pressure-regulating valve (9) is arranged in the return line (8). <IMAGE>
