Transmission hydraulic control system having a pump bypass valve |
摘要 |
A system for providing pressurized hydraulic fluid in a transmission of a motor vehicle includes a pump for providing pressurized hydraulic fluid having an inlet port and an outlet port. A bypass valve includes an inlet port in communication with the outlet port of the pump, a first outlet port in communication with the inlet port of the pump, and a second outlet port. The inlet port of the bypass valve is in communication with the second outlet port of the bypass valve when the bypass valve is in a first position and the inlet port of the bypass valve is in communication with the first outlet port of the bypass valve when the bypass valve is in a second position. A control device and accumulator are operatively associated with the bypass valve. |
