发明名称 Transmission hydraulic control system having a dual element pump
摘要 A hydraulic control system for a transmission includes a motor, a sump for storing a hydraulic fluid, and a dual element pump connected to the motor. The dual element pump has at least one input port connected to the sump, a first outlet port, and a second outlet port. The dual element pump provides a first volume of hydraulic fluid to the first outlet port and provides a second volume of hydraulic fluid to the second outlet port. The first volume is greater than the second volume. The first outlet port is connected to a diversion valve. The second outlet port is connected to a high pressure hydraulic circuit. The diversion valve is operable to transmit the hydraulic fluid from the first outlet port to a low pressure hydraulic circuit and the high pressure hydraulic circuit.
