摘要： A slide valve is described, in particular, for an automatic transmission for motor vehicles. The slide valve includes a valve slide displaceable in a sliding channel and at least two adjacent connecting channels. The sliding channel and the valve slide are configured so that the valve slide in an opened slide position establishes a fluid connection between the two adjacent connecting channels, and the valve slide in the opened slide position is guided in a section of the sliding channel between the adjacent connecting channels.

摘要： A hydraulic control unit for an automatic transmission has a mechanically-operated oil pump (6), an electrically-operated oil pump (106) actuated while an engine (2) is automatically shut down, and a hydraulic pressure circuit (100) which controls supply of hydraulic pressure to a frictional engagement element (40, 60) to be engaged, in the automatic transmission, at a vehicle's start. In the hydraulic pressure circuit, discharge oil from the electrically-operated oil pump is drained from a predetermined drain portion (154) when a selector valve (120) is in the first state (in which the mechanically-operated oil pump is a source of the supply of the hydraulic pressure to the frictional engagement element), whereas less discharge oil is drained from the drain portion, compared to the first state, when the selector valve (120) is in the second state (in which the electrically-operated oil pump is the source of the supply of the hydraulic pressure).

摘要： A fitting clearance of a relief valve functions as an air bleeding orifice. When a discharge pressure reaches a relief pressure so that the relief valve turns into a relief state, a spool is moved so as to limit flow-out of hydraulic oil through the fitting clearance. As a result, generation of air trapping is suppressed by air bleeding function of the relief valve in a closed state. Air in a discharge oil passage is discharged quickly in the initial period of the startup of an electric oil pump, thereby improving rise-up of discharge pressure. During normal pump operation in which the relief valve is held in a relief state, pressure loss due to flow out of the hydraulic oil from the fitting clearance is suppressed and consequently, an electric oil pump having substantially the same discharge performance as conventionally can be used.
摘要翻译：安全阀的安装间隙用作排气孔。当排出压力达到安全压力使得安全阀变为释放状态时，阀芯被移动以限制液压油通过安装间隙的流出。结果，在关闭状态下，溢流阀的排气功能抑制了空气捕集的产生。在电动油泵启动初期，排放油通道中的空气迅速排出，从而改善了排出压力的上升。在安全阀保持在释放状态的正常泵操作期间，由于从装配间隙流出液压油的压力损失被抑制，因此可以使用具有与以往相同的放电性能的电动油泵。

摘要： A shift lock-out device is used with a gearbox containing one or more gears and a clutch mechanism that is operable to selectively engage the one or more gears to provide first and second gear ratios. The shift lock-out device includes a housing having an inlet port that communicates with a source of pressurized fluid and an outlet port that communicates with the clutch mechanism. A valve element is supported within the housing for movement between an opened position, wherein fluid communication is permitted from the inlet port to the outlet port, and a closed position, wherein fluid communication is prevented from the inlet port and an outlet port. A pilot control valve selectively permits and prevents the application of pressurized fluid from a pilot fluid source against the valve element to selectively move the valve element between the opened and closed positions.
