Hydraulic control device for the clutch is engaged directly mounted in a torque converter

摘要

The present invention relates to a hydraulic control device for a clutch in direct engagement (10) is assembled in a torque converter (60), which comprises: & br / - a valve of the modulation (40) comprising, in particular, a valve element with a spring (41) located in order to modulate the pressure of the line of the fluid supplied to the passage of fluid inlet (p3) from the feed passage of fluid (p1, p2), in order to supply pressurized fluid to be modulated to the passage of fluid side of the clutch release bearing (p6) is taken directly from the passage of fluid from the output (p4), and & br / - a valve for controlling locking (50) comprising, in particular, a valve element with a spring (51) which can be moved between a first position in order to disengage the clutch is in direct engagement (10), and a second position in order to produce the clutch of the clutch is in direct engagement (10). br / thanks to this hydraulic control device of simple embodiment, the clutch is carried out in a manner which is soft, without shock.
