    摘要: A system for regulating pressure supplied to a transmission control element, includes a control pressure source and line pressure source, a latch valve that opens and closes communication with the line pressure source in response to control pressure, and a regulator valve including a spool for regulating line pressure and producing control element pressure when the latch valve is closed, and an auxiliary piston responsive to line pressure and contacting the spool for connecting line pressure to the control element when the latch valve is open.

    摘要: A valve-actuator for a hydraulic valve includes a valve chamber, ports spaced mutually and opening into the chamber, a spool axially located in the chamber for opening and closing hydraulic connections between at least two of the ports as the spool moves axially in the chamber. An actuator includes a housing having mutually spaced surfaces, and a piezoelectric element located in the housing between the surfaces, the element expanding and contracting in response to an electric signal applied to the element. A temperature compensation and motion damping circuit comprising feedback resistors and a thermistor. The spool moves axially in the chamber in response to expansion and contraction of the element.
