When the speed control pedal is stepped on and
in
forward, the variable swash plate is tilted as shown
in
figure
above.
As the pump cylinder block rotates with the input shaft, oil is forced out
of
pump port B at high pressure. As
pressure oil enters motor port
D,
the pistons, which align with port D, are pushed against the swashplate and slide
down the inclined surface.
Then the output shaft rotates with the motor cylinder block. This drives the machine forward and the angle
of
pump
swash plate determines the output shaft speed.
As the motor cylinder block continues to rotate, oil is forced out
of
motor port C at low pressure and returns to the
pump.
