Cutaway Over-center variable displacement pump

This cutaway gives learners a complete internal view of an over-center axial piston pump, including the swashplate, pistons, pressure relief valve, and charge pump assembly. With multiple strategic cutaways and a manual rotation knob, students can visualize displacement changes and internal oil paths as the pump cycles. Ideal for teaching pump control, pressure compensation, and charge circuit operation.

Educational Advantages

The housing is cut away to expose all the internal components.

The barrel is also cut away through to the drive shaft.

The swashplate is equipped with a handle that makes it possible to operate the swashplate.

The rear mounted gerotor type charge pump features a completely transparent housing, which also exposes the charge pressure relief valve.

The pump is also equipped with dual main pressure relief valves, and a towing by-pass valve.

A large knob is affixed to the input drive shaft to make it simple to rotate.

This exquisitely handcrafted model makes it easy for students to see exactly how moving the swashplate over-the-center makes it possible to reverse pump flow while the input drive shaft is rotating in the same direction of rotation.
