    • The invention concerns a transmission oil circuit with an oil pump for feeding oil or another fluid from an oil sump or corresponding fluid sump; with a heat exchanger, the oil flows through, for evacuating the heat from the oil; with a work pressure valve, against which the oil pump conveys the oil, so as to bring the conveyed oil to a preset work pressure for pressure actuation, applying hydraulic pressure or conveying hydraulic pressure to switching valves and/or other transmission components and/or other units outside the transmission, which are arranged in the flow direction upstream of the work pressure valve in a row with respect thereto or in the flow direction downstream of a supply line, which branches off in the transmission oil circuit upstream of the work pressure valve. The invention is characterised in that the heat exchanger can be switched alternately into a first position upstream of the work pressure valve or into a second position downstream of the work pressure valve as regards the circulation sequence of the oil coming out of the oil pump, or the heat exchanger can be switched alternately into a first position upstream of the switching valves or into a second position downstream of the switching valves as regards the circulation sequence of the oil coming out of the oil pump, other transmission components and/or other units in an arrangement inside or downstream of the branched off supply line, upstream or downstream of the branch-off point.

    • An electromagnetic pump has a solenoid reciprocating a piston that abuts the ball of a first, one-way ball valve coaxially aligned with the piston axis. In the abutting position the piston closes the valve and provides a pump chamber of very small volume. An second, one-way outlet valve is located orthogonal to the first valve to provide a compact structure and further minimize the volume of the pump chamber. A plurality of these inlet valves can be arranged so the pistons are parallel and activated by a single, solenoid activated piston, with the outlet valves being radially orientated to provide a compact structure that simultaneously provides precise fluid amounts to a plurality of locations, such as multiple pistons of a two cycle engine.
    • 电磁泵具有螺线管往复运动的活塞,其邻接与活塞轴线同轴对准的第一单向球阀的球。 在邻接位置,活塞关闭阀门并提供非常小体积的泵室。 第二单向出口阀定位成与第一阀正交,以提供紧凑的结构并进一步使泵室的体积最小化。 多个这些入口阀可以被布置成使得活塞平行并由单个螺线管活塞活塞激活,出口阀径向地定向以提供紧凑的结构,其同时向多个位置提供精确的流体量,例如 双循环发动机的多个活塞。
