    摘要： A device is described for controlling a hydraulic accumulator of a hydraulic system, for example a vehicle transmission, having a valve device which may connect and disconnect an accumulator-side port of the device to and from a system-side port, the valve device including at least one first check valve which is situated hydraulically between the accumulator-side port and the system-side port, and which is blocking in the direction of the system-side port, the valve device also including an electrically actuated control valve which is situated between a control port of the first check valve and the accumulator-side port in such a way that the control valve may hydraulically unblock the first check valve, using the pressure prevailing at the accumulator-side port.

    摘要： A method for controlling an electromagnetic valve, in particular for an automatic transmission of a motor vehicle. With known methods, electromagnetic valves are triggered with a pulse-width-modulated signal having a constant clock frequency. The object is to provide a method by which a rapid response characteristic and a high adjustment precision of the electromagnetic valve are made possible. The specific properties of a hydraulic system in which electromagnetic valves are used, in particular the rigidity and damping, are not constant but instead change considerably under different operating states of the hydraulic system and/or with different performance quantities of the electromagnetic valve. These different properties are taken into account through the change in the clock frequency as a function of performance quantities of the electromagnetic valve. The clock frequency may thus be optimally adapted to the properties of the hydraulic system, and a rapid response characteristic and a high adjustment precision are achieved.

    摘要： An electromagnetically actuable proportional hydraulic valve (10) is described, which is distinguished in particular by a constant, low-wear operating performance. This is attained by means of a closing member (60) having an approximately conical sealing body (60c, 70) with a curved dome-like face end oriented toward the valve seat (58). The sealing body (60c, 70) together with the valve seat (58) forms a conical seat valve. The sealing body of the closing member (60) is provided with a flow separation edge (60d), which improves the temperature sensitivity of the proportional valve (10).

    摘要： The invention is based on an apparatus (10) for regulating the pressure in a hydraulic circuit that comprises an electrically triggerable pressure-control valve (12), a receptacle device (14) in which the pressure-control valve (12) is installed, and means (54, 64) for damping pressure pulsations. In order to save space, simplify the manufacture of the receptacle device (14), and save additional holding elements, it is proposed according to the invention that the means (54, 64) for damping pressure pulsations be designed as integral components of the pressure-control valve (12).

    摘要： A pressure regulating valve (10) includes a magnet coil (16) received in a coil body (18), an armature (26) movable relative to a pole piece (20) for actuating a valve closing member (36), and a magnetic circuit (48) containing a magnet yoke (50). The magnetic circuit (48) has a maximum of three components (20, 66; 26, 50) that together form magnetic transitions (72, 74) oriented in the axial direction.
