摘要: A rotary control valve for a vehicle hydrostatic transmission includes a hydraulic pump and a hydraulic motor. The valve is configured to control both a direction and a speed of the hydrostatic transmission. The rotary control valve includes a rotary valve plate configured to oscillate through a range of less than 180 degrees independently of the pump and the motor.
