摘要： A system for charging and discharging at least one hydraulic accumulator (10) can be connected to a valve control device (12). The valve control device (12) has at least one logic valve (14). A shuttle valve (16) and a hydraulically operated switching valve (18) are also provided. The valves (14, 16, 18) are interconnected such that the hydraulically actuatable switching valve (18) compares the accumulator pressure (pA) to a minimum accumulator pressure (pA0) that can be adjusted via the control pressure setting of this switching valve (18).

摘要： A valve, in particular a 4/2-way slide valve (60), includes a valve piston (67), which is guided in a longitudinally movable manner in a valve housing (25), for selectively connecting and disconnecting fluid connections in the valve housing (25), such as a pressure supply connection (P), a tank connection (T), and two utility connections (A, B). A magnetic system (49), to which current can be supplied, controls the valve piston (67). When no current is supplied to the magnetic system (49), the control pressure at one of the utility connections (A, B) can be set, in particular limited, by a control device (62, 70, 79, 80, 88) arranged in the valve housing.

摘要： A system for hydraulic systems includes a working cylinder (58) which operates as a consumer of hydraulic energy or as a generator of hydraulic energy. A hydraulic accumulator (1) can be charged by the working cylinder for storing energy and can be discharged for delivering energy to the working cylinder (58). One hydraulic accumulator is provided in the form of an adjustable hydropneumatic piston accumulator (1), in which with a plurality of pressure chambers (19, 21, 23, 25) adjoining effective surfaces (11, 13, 15, 17) of different sizes are on the fluid side of the accumulator piston (5). An adjusting arrangement (51) connects a selected pressure chamber (19, 21, 23, 25) or a plurality of selected pressure chambers (19, 21, 23, 25) of the piston accumulator (1) to the working cylinder (58) as a function of the pressure level that prevails respectively on the gas side of the piston accumulator (1) and on the working cylinder (58).

摘要： A valve, in particular for hydraulic circuits, includes a valve body (4) designed as a cartridge that can be fixed in a housing (6) having fluid connections (8) by a securing device (20, 26, 28). The securing device has at least one blocking element (20) in the form of a separate component between the valve body (4) and the housing (6). The blocking element has blocking surfaces that can be moved relative to the longitudinal axis (18) of the valve body (4) between an assembly position allowing the valve body (4) to be inserted into the housing (6) and a blocking position in which the blocking surfaces secure the valve body in an assembly position, preferably with zero backlash by bearing against retaining surfaces (26, 28) of the housing (6) and the valve body (4).

摘要： A valve (18), for a valve assembly (10) for regulating the pressure of a fluid guided in a hydraulic system for supplying pressure to at least one hydraulic consumer (12a, 12b), includes a pilot control stage (48) and a main control stage (38) for at least partially clearing or blocking a fluid path from a supply connection (P) to an outflow connection (T). A relief stage (54) for pressure relief of a fluid chamber is arranged between the pilot control stage (48) and the main control stage (38). The relief stage (54) compares the existing load pressure at load terminal (LS) dedicated to the hydraulic consumer (12a, 12b) with the outflow pressure at the outflow connection (T), clearing the pressure relief if both pressures are approximately the same. The relief stage (54) can be directly connected to the load connection (LS) and can be charged with load pressure.

摘要： A proportional throttle valve includes a valve piston (2) functioning as a variable orifice and displaceably guided in the longitudinal direction in a valve housing (3) having a fluid inlet (4) and a fluid outlet (5). Since a leading edge (6) of the valve piston (2) is formed by a control piston (7) of a flow regulator (8) for the fluid connection of the fluid inlet (4) and the fluid outlet (5), the flow control valve and the proportional throttle valve are functionally combined in one valve unit.

摘要： A proportional pressure control valve includes a valve box (10) having a pump (P), user (A) and reservoir (T) connections. Control piston (18) is guided in a longitudinally displaceably inside the valve box (10) for optionally connecting the pump connection (P) to the user connection (A) and the user connection (A) to the reservoir connection (T). A fluid-carrying connection is established between the pump connection (P) and a pilot chamber (20) of a pilot valve (22). The pilot valve (22) is controlled by a magnet system, especially a proportional magnet system (28). The proportional pressure control valve, for the fluid-carrying connection to the pilot chamber (20), has a bore (27) extending axially inside the wall of the valve box (10) and from a radial bore (9) of the housing (10) forming the pump connection (P).

摘要： A test device for a fluidic pump device (10), which can be driven by a drive device and of which the pump rotational speed that leads to a defined fluid volumetric flow on the output side (12) of the pump device (10) is known, is characterized in that the fluid volumetric flow is conducted at least temporarily via a pressure influencing device (22) which, during operation of the pump device (10), brings about a pressure drop, by way of the decrease of which an evaluation device (32) makes a statement about a reduced functional capability of the pump device (10) possible.
