Manual Displacement Motor Control
A Standard Displacement Control is also used on
Variable Displacement Motors. This motor control will
provide output speed or torque (displacement) in
relation to the angular movement of the control handle
between the maximum and minimum displacements of
the motor. Release of the control handle results in the
motor returning to its maximum displacement. The
overcome external control linkage friction.
Torque on the control handle shaft
must not exceed 150 in. lbs.
Motor Pressure Compensator Control
A Motor Pressure Compensator Control is available for
the Variable Displacement Motor. The control is
designed to keep the displacement of the motor at a
maintaining motor output RPM's at a maximum. When
a heavy load is induced on the motor, the control shifts
the swashplate to maximum displacement. This
reduces the motor speed but increases the torque to
produce a greater load capacity. The "shift" in the
position of the swashplate is made automatically at a
pre-selected shift pressure.
The rotary by-pass valve is a two (2) way, two position
valve mounted on the motor manifold. During normal
operation, the valve remains in the closed position
which does not allow any fluid to be by-passed. In the
open position, the main flow is by-passed from the
motor to the down stream side of the main circuit. The
by-pass valve is designed for use with all heavy duty
motors and provides the capability of disconnecting the
power train for safety purposes or moving the vehicle in
case of machine malfunction.
