Cylinder Cylinder
Piston
Pump and motor cylinder, each containing pistons,
are connected by lines. Cylinders and lines are filled
with oil. Pistons ride against swashplates located in
pump and motor.
In
the pump, as the cylinder rotates, pistons move
across the sloping face of swashplate and slide
in
or out
of their cylinder bores.
The
oil, forced out by the pump
pistons, causes the motor pistons to slide out of their
cylinder bores.
In
the motor, sliding out of the cylinder and moving
across the sloping face of swashplate, the pistons rotate
the cylinder.
