Abstract
An apparatus including a first piston member rotatable about a first rotational axis and a rotor with a first chamber and pivotable about a second rotational axis. The first piston member extends across the first chamber. The rotor and first piston member are rotatable around the first rotational axis, and the rotor is pivotable about the second rotational axis to permit a relative pivoting motion between the rotor and the first piston member linked to the rotor rotating about the first rotational axis.
Claims1
A method of operation of a rotary fluid apparatus that comprises
- a first piston member being rotatable about a first rotational axis;
- a rotor comprising a first chamber and pivotable about a second rotational axis, the first piston member extending across the first chamber to form sub-chambers within the first chamber;
- the method comprising:
- rotating the rotor and first piston member around the first rotational axis;
- and
- pivoting the rotor about the second rotational axis
- such that there is a relative pivoting motion between the rotor and the first piston member
- which varies the volume of each of the sub-chambers,
- with the change in the sub-chambers volume being linked to rotation of the rotor about the first rotational axis.
