摘要： A hydrostatic transmission system having a pump and a motor, and a manually controlled bypass valve for creating a short circuit that includes the motor and not the pump, the bypass valve being located closer to the motor than the pump. In a preferred embodiment the bypass passage is located within a housing of a motor of a hydrostatic transmission system and includes a manually controlled valve member that when open and closed respectively permits and blocks flow of fluid between the supply and return line. More particularly, the bypass valve may be integral with the motor of the hydrostatic transmission, and the motor may be a gerotor motor.
