    摘要： A pneumatic valve, in particular a pneumatic proportional pressure control valve, comprising a valve housing (3), in which a piston-like valve element (5) is guided axially movably in a guide (7) and, under the effect of an actuating device (9) for the valve element (5) and of a restoring device (11), which exerts a spring force and acts on the valve element (5) counter to the applied magnetic force (FB) of the actuating device (9), controls a media flow at least between at least a first media connection (13) and a second media connection (15) on the valve housing (3), is characterized in that, with the activation of the actuating device (9), the valve element (5) establishes a media-conducting connection (17) between the respective media connections (13, 15), while allowing for the forces prevailing, on the basis of the applied pressures multiplied by the respectively pressure-effective surfaces, the spring force, the flow forces and the magnetic force.

    摘要： The invention relates to a drive system having at least one hydraulic actuator (2), which is supplied with pressure medium (4) by means of at least one pressure-medium pump (3) in a main circuit, the pressure-medium pump (3) being a rotational-speed-controlled pressure-medium pump that is driven by a motor (5) at a variable rotational speed and a controlled torque, said drive system being characterized in that leakage fluid (7) that escapes from a displacement chamber (6) of the pressure-medium pump (3) is discharged through a fluid-conducting connection (8) having at least one check valve (9, 16), and the at least one check valve (9, 16) is installed in the fluid-conducting connection (8) in such a way that the check valve prevents pressure medium from flowing back out of the main circuit into the displacement chamber (6) or another interior chamber of the pressure-medium pump (3) and feeds leakage fluid (7) into the main circuit of the drive system (1) when there is a slight excess pressure.

    摘要： The invention relates to a valve device for a hydraulic circuit (10), which valve device divides the incoming volume flow into at least two pre-determined partial flows for supplying hydraulic consumers (V1, V2) of the circuit (10), which valve device has at least one pressure balance (16) and at least one orifice. As a result of the fact that the orifice is embodied as a variable orifice (32) which can be controlled by means of a proportional magnet (34) in such a way that the opening area of said orifice varies, a type of flow regulator is realized which can switch the regulated volume flow and/or proportionally adjust the regulated volume flow in a defined manner.
