    Abstract: The invention relates to a valve, in particular for use in hydraulic circuits, comprising a valve body (4) which is designed as a cartridge, can be integrated into a housing (6) that has fluid connections (8), and can be fixed in the housing by means of a securing device (20, 26, 28). The invention is characterized in that the securing device has at least one blocking element (20) in the form of a separate component which can be found between the valve body (4) and the housing (6), said blocking element having blocking surfaces that can be moved relative to the longitudinal axis (18) of the valve body (4) between an assembly position which allows 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).

    Abstract: Disclosed is a method for adjusting an actuation of a proportional valve (10) for its functional operation as part of a fluid system (14), comprising the following steps: acquiring measurements of the proportional valve (10) during its operation outside the fluid system (14); preparing a characteristic diagram (12) based on the measurements; integrating the proportional valve (10) into the fluid system (14), and adapting the actuation of the proportional valve (10) to the fluid system (14) on the basis of the characteristic diagram (12) by means of a control device (18). A corresponding fluid system (14) and an industrial truck with such a fluid system (14) are also disclosed.

    Abstract: 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).

    Abstract: 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).
