the size of which depends on the pitch of the cradle. The slipper pads are held on
with the pistons and guided along the glide surface of the cradle by the retaining
plate. The inclined position of the cradle during arotation causes each piston
to move over the bottom and top dead centers and back to its initial position.
Here, hydraulic fluid is fed into and out through two control slots in the distributor
plateaccording to the displacement. Hydraulic fluid flows into the piston chamber
as the piston recedes on the suction side. At the same time, the hydraulic fluid is
pushed out of the cylinder chamber into the hydraulic system by the pistons on
the high-pressure side.
The swivel angle of the cradleis infinitely variable. Adjusting the swivel angle
changes the piston stroke and, with it, the displacement. The swivel angle is
controlled hydraulically by means of the stroking piston. The cradle is mounted in
swivel bearings for smooth operation and it is kept in balance by the opposed
piston. Increasing the swivel angle increases the displacement; reducing the angle
reduces displacement accordingly.
The swivel angle of the cradleis infinitely variable. Adjusting the swivel angle
changes the piston stroke and, with it, the displacement. The swivel angle is
controlled hydraulically by means of the stroking piston. The cradle is mounted for
easy motion in swivel bearings. When pressurized, the cradle is held in balance by
the swiveling forces of the rotary group, which are generated by the eccentrically
mounted cradle and by the control pressure. When depressurized, the spring
presses the cradle to the maximum swivel angle. Increasing the swivel angle
increases the displacement; reducing the angle reduces displacement accordingly.
Various control devices are available depending on requirements.
