    Abstract: A hydraulic arrangement by which a plurality of shift rails of a transmission are actuated, including one double acting cylinder per shift rail by which the respective shift rail can be moved back and forth. A first hydraulic valve is connected upstream of the plurality of shift rails and has a first output and a second output, by which a first shift pressure and a second shift pressure for actuating the shift rails can be provided. A second hydraulic valve is connected between the first hydraulic valve and two of the shift rails, and by which it is selectively possible for the first output of the first hydraulic valve to be associated with one of the double acting cylinders of the two shift rails, and the second output of the first hydraulic valve to be associated with the other double acting cylinder of the two shift rails.

    Abstract: A hydraulic system including a pump for feeding hydraulic fluid from an inlet side to an outlet side. A pressure accumulator is disposed at the outlet side, and between the pump and the pressure accumulator a hydraulic control valve is disposed, which has at least two valve positions. The outlet side of the pump is connected to the pressure accumulator in a second valve position, and is separated from the pressure accumulator in a first valve position. The outlet side of the pump is connected to the inlet side through the control valve in the first valve position.

    Abstract: A hydraulic supply system for a hydraulically-operated automatic transmission includes a primary pump that is driven by an internal combustion engine of a vehicle. An electrically-driven auxiliary pump is provided to supply the system with hydraulic pressure when the primary pump is off or to supplement the primary pump when the primary pump does not deliver sufficient pressure. A discharge line from the auxiliary pump is connected to a control line of the hydraulic supply system and to the hydraulic system supply line under system pressure. Check valves are provided in the respective lines from the auxiliary pump. An additional check valve is provided in a line that extends from the control line to a torque sensing chamber of the automatic transmission.
