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.
Claims17
A method of operation of a rotary fluid apparatus that comprises:
- a first piston member defining a first rotational axis and being rotatable about the first rotational axis;
- and
- a rotor comprising a first chamber and pivotable about a second rotational axis, the second rotational axis being perpendicular to the first rotational axis, the first piston member extending across the first chamber to divide the first chamber to form double-acting sub-chambers;
- 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 a volume of each of the sub-chambers of the first chamber, with the change in the sub-chambers volume being linked to rotation of the rotor about the first rotational axis.

A rotary fluid apparatus comprising:
- a first piston member defining a first rotational axis and being rotatable about the first rotational axis;
- and
- a rotor comprising a first chamber and pivotable about a second rotational axis, the second rotational axis being perpendicular to the first rotational axis, the first piston member extending across the first chamber to divide the first chamber to form double-acting sub-chambers, whereby:
- the rotor and an axle are rotatable with a shaft around the first rotational axis;
- and
- the rotor is pivotable about the second rotational axis to permit relative pivoting motion between the rotor and the first piston member as the rotor rotates about the first rotational axis.
