ABSTRACT:
A valve spool and a piston are disposed substantially parallel to each other and are pivotably connected with a lever which is movable by the accelerator pedal of a prime mover. The force differential biasing the valve spool to withstand the force of the lever tending to move the valve spool is approximately zero. The valve spool has a valve land with a width equal to that of a port connected with a throttle pressure passage, and a constant neutral position in which the valve land registers with the port and hydraulic pressure in the passageway is equal to a throttle pressure depending on the position of the accelerator pedal. The piston is biased by the hydraulic pressure in the passageway and a spring in opposite directions to cause the valve spool to occupy the netural position.
