摘要： A rotary vane pump for delivering a fluid and which has a housing which accommodates a rotatable delivery device (1) and which includes a feed channel (13) for receiving the fluid from a tank or the like. The feed channel communicates with a jet chamber (15) which in turn communicates via one or more suction channels (20) to at least two suction chambers which communicate with the intake region of the pump. An injector device (14) injects a pressurized fluid into the jet chamber to entrain and advance the fluid entering from the feed channel (13), and means are provided for influencing the flow of the fluid so as to achieve essentially the same volume flow into the two suction chambers.

摘要： An expansion element for a CO2 motor vehicle air conditioner includes a valve unit which can be used particularly for such an expansion element and which has a fixed throttle between an upstream valve high-pressure side and a downstream valve low-pressure side. The expansion element contains a control valve which is acted upon by the low-pressure-side refrigerant pressure or a physical quantity connected therewith as the correcting variable, or valve unit. The valve unit contains a fixed throttle and at least one additional valve component in the form of a pressure control valve which is arranged in a bypass line bypassing the fixed throttle, or in the form of a control vale influencing the passage cross-section of the fixed throttle.

摘要： The friction clutch between the engine and an automated transmission in the power train of a motor vehicle are operated and controlled by an actuator which effects changes in the extent of engagement of the clutch as well as the selection of and shifting into particular gears. The actuator forms part of a unit which receives a pressurized hydraulic fluid from a source including an accumulator and a proportional valve which latter selects the fluid pressure necessary to shift the transmission into a selected gear.
