    摘要: A proportional pressure control valve is described, which comprises a valve part (1) with outlet and inlet openings (4) and at least one closing element (2) for the control of an orifice (5). The hydraulically effective cross-section of the valve part (1) is determined by the size and shape of the inlet opening (4). The axial longitudinal axis of the inlet opening (4) is perpendicular to the longitudinal axis of the closing element (2). The resultant force action on the closing element (2) has an advantageous effect on the quality of the valve function especially at low temperatures.

    摘要: An automatic transmission control device with a hydraulic control system controlled by an electric transmission control device. The system including several pressure control valves, actuated electrically by the transmission control device, and several switching valves and pressure regulation valves, actuated by hydraulic pilot pressure, which is adjustable with the pressure control valves. Each shift element is associated with one of the pressure control valve. An engagement prevention valve is actuated by one of a control pressure of the first shift element and a pressure signal equivalent to the control pressure of the first shift element to engage the reverse drive gear. A pressure supply line of the second shift element for obtaining the reversing gear is blocked when the engagement prevention valve is in its first switch position and open when the engagement prevention valve is in its second switch position.

    摘要: A control valve arrangement having a clutch regulation valve (3), which pressurizes a device to actuate the clutch, and a valve that produces a controlled pilot pressure (P_VST3). An electronic control unit (ECU) controls a valve to supply a control valve with the pressure (P_VST3). The arrangement further having a hydraulic system which, if the ECU fails and the pressure (P_VST3) ceases, the last shift condition of the clutch actuation device, prior to the ECU failure, can be maintained in an emergency. The arrangement includes a valve, which delivers an activation pressure (P_A), depending on an engine-speed-dependent control pressure (P_D), to an actuation valve (2), which then delivers the pressure (P_A) to the valve (3) to prevent the emergency function initiation despite a lack of pressure (P_VST3) and existence of the pressure (P_D) sufficiently high to initiate the emergency function.

    摘要: A device for operating a starter mechanism actively connected with a hydraulic supply circuit of a transmission unit. The starter mechanism has a piston chamber subject to hydraulic pressure for activating a frictional shift element and a hydraulic chamber subject to hydraulic pressure for the cooling and lubricating an area of the starter mechanism. A hydraulic pressure between a lubrication pressure control port of a second pressure relief valve and the hydraulic chamber and equivalent to a lubrication pressure, is exerted on a second back pressure outlet port of a first relief valve, which acts on a valve slide of the first relief valve in the opposite direction relative to the working pressure exerted on a first back pressure outlet port of the first relief valve so that the pressure feed-back of the hydraulic pressure to the first relief valve occurs additively to the pilot signal characteristic of the first relief valve.
