    摘要: Fluid pressure for engagement of a clutch is controlled by a valve alternating between supply and drain conditions in response to a high frequency electrical square wave signal. The valve produces a low flow pilot pressure signal which controls clutch engagement pressure through a valve incorporating a piston which allows clutch engagement pressure to drain whenever that pressure exceeds pilot pressure.
