The inclined block hydraulic mechanism is the base element of the axial piston pumps which is completely united. That is valid for all types except for PM pump which is a wobbling one.
Axial Piston Units
F1A
Fixed primary units (pumps) and secondary units (fast motors) are used within mobile equipments and in industrial hydrostatic transmissions. These units are used in open and closed circuit.
Variable primary units (pumps) mounted outside the oil tank (K type capsulated) or in the tank (N type uncapsulated) are use in industrial transmissions. They could be used in tilting closed circuit both drive rotation (changing the flow drive rotation) , in tilting open circuit one drive rotation and in semi-open circuit.
Variable pumps only one drive rotation tilting are developped especially for hydrostatic driving within mobile equipment , in open circuit (ex. : force cylinder driving).
Variable secondary units (fast motors) are developped especially for moving. Usually are used in closed circuit but they could be used in open circuit.
Axial piston pump type PM is a constant displacement hydraulic generator, with axial pistons and swash axlle meant to be used within power hydrostatic installations of autodumping vehicles.
