The work holding section 614 is in the shape of a circular arc concentric with the main cam 6. The work holding section 614 is used for holding the piston 3 stationary relative to the piston cavity 21 by the main driving element 62 after the rotor 2 rotates until the piston 3 is inserted into the work groove 13.

More specifically, the work holding section 614 is used for holding the piston 3 stationary relative to the piston cavity 21 by the main driving element 62 after the rotor 2 rotates until the top surface of the piston 3 is attached to the groove bottom surface of the work groove 13, and holding the top surface of the piston 3 attached to the groove bottom surface of the work groove 13. The work holding section 614 may be a circular arc-shaped groove having a center on the axis of the rotor 2.

More specifically, the insertion section 613 is configured to push the piston 3 to slide along the wall surface at the opposite end of the working groove 13 by the main driving element 62, and the abutting slope surface 32 of the piston 3 is abutted and slid along the wall surface at the opposite end of the working groove 13.

More specifically, the opening cam 46 and the closing cam 47 are fixed coaxially with the main cam 6 to form a cam group.
