ABSTRACT:
There is provided an improved fluidic drive circuit for a fluid powered vehicle arranged to limit flow to an unloaded drive wheel. A restricting orifice is mounted in parallel with a pressure sensitive control valve to provide fluid power to the motor. A trickle flow is provided through the restricting orifice to maintain a minimum pressure to the fluid motor. The control valve, sensitive to pressure at the fluid motor, provides full flow only when the pressure in the fluid motor is sufficient.
