Pressure control apparatus for a torque-transmitting mechanism
A pressure control apparatus is disposed in a pressure control system for a transmission to set pressure control at a torque-transmitting mechanism. The pressure control apparatus includes a torque-transmitting mechanism control valve, which distributes pressure from a high pressure source to the torque-transmitting mechanism. Also within the pressure control apparatus is a boost valve mechanism, which is effective to control feedback pressure on the torque transmitting mechanism pressure regulator valve thereby controlling the pressure rise at the torque-transmitting mechanism and also permitting a boost pressure to be distributed to the torque-transmitting mechanism when full engagement thereof is required.
