    Abstract: A positive-displacement pump having an eccentrically positioned internal ring gear and pinion within a pump housing. Pressurized operating fluid is provided by the pump to actuate an actuation piston of a clutch unit, such as a double clutch unit. The clutch unit is drivingly coupled with the pump for movement between engaged and disengaged positions. At least one throughbore is provided in the pump housing within which throughbore the clutch actuation piston is guided.

    Abstract: A continuously variable transmission for a motor vehicle. The transmission includes an adjustable width drive pulley and an adjustable width output pulley that are drivingly connected by an endless torque-transmitting member. The drive pulley includes a spring to bias the movable element of the pulley toward a position at which the spacing between the conical disks that define the pulley are at a minimum, to avoid damage to the transmission when the vehicle is being towed.

    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.

    Abstract: A hydraulic arrangement for controlling a transmission connected downstream of an internal combustion engine having a start-stop device. A hydraulic energy source provides hydraulic energy, an energy accumulator is connected downstream of the hydraulic energy source for storing and dispensing hydraulic energy provided by the hydraulic energy source, and a hydraulic controller is associated with the hydraulic energy source and the energy accumulator for controlling the transmission. The energy accumulator is associated with the hydraulic controller by a branch line to a pilot control circuit.

    Abstract: A hydraulic system having at least one hydraulic valve for controlling a transmission, in particular a continuously variable transmission. The hydraulic valve is controlled by a pilot circuit including at least one control element having a variable flow resistance and one control element having a constant flow resistance. The control element having a variable flow resistance is connected upstream of the control element having a constant flow resistance.

    Abstract: A pressure limiting valve having a spool with raised spool lands. The spool is slidably received in a spool bore having inflow and outflow grooves that form control edges. The valve has two control edges, and a hydraulic resistance is connected in series with one of the control edges. Increasing static pressure losses at the control edges during flow, so-called flow forces, can be offset by an increasing back pressure on the valve spool, which is produced by the hydraulic resistance.
