摘要： A 2-position, 3-way directional control valve is described which prevents reverse flow from an actuator port to a pressure port in one position. In the preferred embodiment described, the valve is solenoid actuated and is spring biased to a drain position, wherein an extension central to a spool assembly penetrates through a check valve seat and lifts a check valve ball from its seat to permit flow from an actuator port to a drain port. In the actuated or energized position, an armature assembly is shifted by a solenoid, drawing the spool assembly within the valve body and establishing a fluid path between a pressure port and the actuator port. In this position the extension of the spool assembly is withdrawn from the check valve seat. The check valve can be unseated by pressure from the pressure port to permit flow from the pressure port, through the spool and the check valve assembly. In the event of loss of pressure from the pressure port, such as due to shifting of other valves coupled to a pressure source, the check valve reseats to prevent reverse flow from the actuator port to the pressure port. The valve assembly is preferably configured as a cartridge valve for use in pre-drilled manifolds.

摘要： An apparatus and method is disclosed for controlling engagement of a power take-off shaft (PTO) on a vehicle. The apparatus includes a clutch including an input shaft coupled to a power source and an output shaft coupled to the PTO. The apparatus also includes an input speed sensor for sensing a quantity related to the angular velocity of the input shaft, an output shaft speed sensor for sensing angular velocity of the output shaft, and a clutch controller for adjusting pressure of hydraulic fluid applied to the clutch in response to control signals. Torque transmitted between the input and output shafts is responsive to the control signals. The apparatus also includes a control circuit coupled to the speed sensors and the clutch controller. The control circuit is configured to receive signals from the speed sensors and to provide the control signals in response thereto. During engagement of the PTO, the control circuit continuously determines an actual acceleration of the PTO based upon the output shaft velocity, and generates the control signals using a desired acceleration and the actual acceleration. The control circuit may continuously determine the desired acceleration based upon the input speed signal. Alternatively, the control circuit may provide control signals to cause the torque transmitted through the clutch to increase at a rate depending upon the difference between the desired and actual accelerations when the actual acceleration is more than a threshold proportion of the desired acceleration, and to cause the torque to increase at a rate independent of the difference when the actual acceleration is less than the threshold proportion.

摘要： A simplified brake control system comprises a source of pressurized fluid, a spring-set brake with a hydraulic release mechanism and a control valve connected between the brake and the source. The control valve has a valve body and a flow control mechanism in the body and mounted for movement between a first (solenoid-energized) position and a second (solenoid-de-energized) position. A one-way check valve is built into the valve body. How the system operates depends upon two factors, namely, (a) whether the valve flow control mechanism is in its first or its second position, and (b) the relationship of the pressure of the source, i.e., the first pressure, and the second pressure in the release mechanism. When the flow control mechanism is in the first position, the release mechanism may be pressurized for brake release. And when such mechanism is in the second position, the release mechanism is vented to the reservoir through the brake port, the second passage and the drain port. A new method for controlling a brake is also disclosed.
