<p><P>PROBLEM TO BE SOLVED: To provide a valve device for preventing shock torque capable of properly controlling a connection time which is a time from the stepping cancellation of a clutch pedal to the connection of an engine and a transmission irrespective of a change in the viscosity of a working fluid. <P>SOLUTION: When thrust by the differential pressure of the working fluid received by a movable valve element 57 is small since the actual viscosity of the working fluid is low, the movable valve element 57 comes in contact with a fixed valve element 55 and the working fluid is refluxed via a throttle hole 53a with a large diameter and a throttle hole 53b with a small diameter (fully throttled) into a master cylinder 11. When the thrust by the differential pressure of the working fluid received by the movable valve element 57 is large since the actual viscosity of the working fluid is high, the movable valve element does not come in contact with the fixed valve element 55 and the working fluid is refluxed via the throttle hole 53a with the large diameter and a step 62 into the master cylinder 11. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
