Abstract | In a solenoid operated valve (50) that serves as a pressure-regulating valve, a second drain port (52d) communicating with a spring chamber (59) is connected to a fluid path (46a) for supplying pressure to the spring chamber, the fluid path being connected to a pressure supply path (48) via a pressure supply check valve (70) and to a fluid path (49b) for supplying pressure to a clutch via an outlet check valve (80). When the solenoid operated valve (50) serves as a pressure regulating valve, the switching valve (60) connects the fluid path (46a) to a drain path (68) to drain fluid in the spring chamber (59). Therefore, the solenoid operated valve (50) can serve not only as a pressure regulating valve but also as a solenoid pump whereby saving the space for installation thereof.
L'invention porte sur une soupape commandée par solénoïde (50) qui sert de soupape de régulation de pression, dans laquelle un second orifice d'évacuation (52d) communiquant avec une chambre à ressort (59) est relié à un trajet de fluide (46a) pour communiquer une pression à la chambre à ressort, le trajet de fluide étant relié à un trajet d'alimentation sous pression (48) par l'intermédiaire d'un clapet anti-retour d'alimentation sous pression (70) et à un trajet de fluide (49b) pour communiquer une pression à un embrayage par l'intermédiaire d'un clapet anti-retour de sortie (80). Lorsque la soupape commandée par solénoïde (50) sert de soupape de régulation de pression, la soupape de commutation (60) relie le trajet de fluide (46a) à un trajet d'évacuation (68) pour évacuer un fluide dans la chambre à ressort (59). Par conséquent, la soupape commandée par solénoïde (50) peut servir non seulement de soupape de régulation de pression mais encore de pompe solénoïde de façon à économiser l'espace pour l'installation de celle-ci. |
