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.

A spherical compressor is provided. A cylinder body and a cylinder head are combined to form a spherical inner cavity. A sliding chute swinging mechanism is arranged between a piston shaft and a piston shaft hole or between a turntable shaft and a turntable shaft hole. The turntable shaft is driven to rotate so that a piston swings along a sliding chute relative to the axis of the piston shaft hole, or a turntable swings along the sliding chute relative to the axis of the turntable shaft hole, so as to form a V1 working chamber and a V2 working chamber with alternatively variable volumes in the spherical inner cavity.

An apparatus comprising a first piston member (22) rotatable about a first rotational axis (30) and a rotor (16) comprising a first chamber (34a) and pivotable about a second rotational axis (32). The first piston member (22) extends across the first chamber (34a). The rotor (16) and first piston member (22) are rotatable around the first rotational axis (30), and the rotor (16) is pivotable about the second rotational axis (32) to permit a relative pivoting motion between the rotor (16) and the first piston member (22) linked to the rotor (16) rotating about the first rotational axis (30).
