摘要： A transmission having a shaft driven by a prime mover such as an engine or motor is provided. The transmission includes a first stationary element for supporting the shaft for rotation, and a torque transmitting device connectable to the shaft and rotatable about an axis. The torque transmitting device is actuated by a hydraulic fluid. A first passage is connected to the torque transmitting device and is in communication with the hydraulic fluid. The first passage extends radially inward from the torque transmitting device. A vent passage is located within the first stationary element and is in communication with the first passage. Rotation of the torque transmitting device about the axis separates entrained air from the fluid and urges air radially inward through the first passage and into the vent passage, thereby removing air from the hydraulic fluid and circuit.

摘要： A plugged filter detection system includes a valve housed within a cavity defining an initial inlet for receiving fluid at an inlet pressure before fluid enters a filter, a final inlet for receiving fluid at an outlet pressure after the fluid exits the filter, and a switch port for directing fluid to a switch to activate the switch. The inlet pressure biases the valve in a first direction and the outlet pressure biases the valve in a second direction substantially opposing the first direction. The valve is movable from a first position to a second position to unblock the switch port, thereby allowing the switch to be activated when inlet pressure is greater than outlet pressure. A spring preferably biases the valve in the second direction, such that inlet pressure must be greater than outlet pressure by at least the spring constant to allow switch activation.

摘要： A hydrodynamic retarder control apparatus includes two valve spools, one, a retarder control valve, functions as a relay valve to control the on/off operation of a hydrodynamic retarder and the other, a regulator valve, functions to control the regulation of pressure at the hydrodynamic retarder. During abnormal periods of operation of the regulator valve, the retarder control valve will also function as a pressure control valve thereby limiting the maximum pressure at the hydrodynamic retarder.

摘要： An electro-hydraulic control system is provided for a transmission with a torque-transmitting mechanism that has a dual area piston. When pressurized fluid is provided to a first of the two piston areas, the position of a spring-biased shift valve controls whether pressurized fluid communicates with the second piston area. A solenoid valve in fluid communication with the shift valve is energizable to direct pressurized fluid to the shift valve to urge the shift valve to the unstroked position to which the spring also urges. The shift valve may also be urged by pressurized fluid to the stroked position, but only when the solenoid valve is not energized. The spring maintains the shift valve in the unstroked position when pressurized fluid is directed to the shift valve to act both against and with the spring.
