The floating cup principle can be made variable by changing the port plate angles on which the barrel plates are rotating.
The small swash angle allows a compact construction of a variable floating cup pump with a power density above conventional variable piston pumps. The control mechanism uses control pistons and cylinders similar to the ones used in the rotation group, minimizing the costs for the control mechanism. Any conventional control (pressure, load sensing etceteras) may be connected to the two front actuators. More details on the variable floating cup pump can be found in the paper 'Design of a Variable Displacement Floating Cup Pump', of which a copy can be requested through the information page of our website.
