CLOSED HYDRAULIC CIRCUIT
Variable Pump/Fixed Motor. This combination provides for a constant torque output at a fixed maximum
pressure over the full speed range. Speed and direction are controlled with a variable displacement over-center pump. Power from
overhauling loads is regenerated back into the pump prime mover. Motor speed is limited to the maximum speed permitted by full
pump displacement. System is capable of full power only at maximum pump displacement.
POWER CHARACTERISTICS OF HYDROSTATIC TRANSMISSIONS
Variable Pump/Variable Motor. This
combination provides for an extended range of motor speeds. The motor, at full displacement, delivers maximum torque while its
speed and direction respond to displacement changes of the crossover center pump. Power is proportional to motor speed. This
transmission system has the capability of constant torque and rising power until the pump reaches full displacement and full power
at elevated speeds as motor displacement and torque are reduced.
