HYDRAULIC CONTROL DEVICE FOR DIRECT JACK CLUTCH MOUNTED IN A TORQUE CONVERTER

摘要

The present invention relates to a hydraulic control device for a direct drive clutch (10) assembled in a torque converter (60), comprising: BR/ - a modulating valve (40) including a valve element spring (41) arranged to modulate the line pressure of the fluid supplied to the inlet fluid passage (P3) from the fluid supply passage (P1, P2) to supply fluid under modulated pressure to the fluid passage the release side (P6) of said direct drive clutch from the output fluid passage (P4), and BR/ - a lock control valve (50) including a spring valve member (51) which can be moved between a first position to disengage said direct drive clutch (10), and a second position to realize the clutch of said direct drive clutch (10). BR/ With this hydraulic control device of simple realization , the clutch performs smoothly, without shock.
