Abstract
The load element state detecting portiondetects the completion of the filling of the hydraulic oil into the clutchand the working limit of the accumulatoron the basis of the displacement of the spool valve element. That is, since the completion of the filling of the hydraulic oil into the clutch and the working limit of the accumulatorare directly detected, so that the completion of the filling of the hydraulic oil into the clutchand the working limit of the accumulatorcan be detected with high precision regardless of differences among products and the time-lapse variation. Furthermore, they can be detected without equipping any special device to the hydraulic control circuit, and thus there is an advantage that the device construction is simple.
