Claim 0:
1. A rotary piston and cylinder device comprising:
a rotor including a rotor surface,
a piston which extends from the rotor surface only partially around the rotor surface,
a stator at least partially enclosing the rotor and having a single continuous and unjointed surface,
a rotatable shutter having a shaft and a single slot,
an annular chamber that at least partially surrounds the rotor, the annular chamber being defined only by the rotor surface and the single continuous and unjointed surface of the stator together and at least a portion of the annular chamber is arc-shaped when viewed in axial cross-section, and
a transmission,
wherein the piston is arranged to rotate through the annular chamber when the rotor rotates and the rotatable shutter rotates being driven through the transmission from the shaft so that the rotation of the rotatable shutter is synchronized to the rotation of the rotor, and the single slot of the rotatable shutter is configured to allow passage of the piston during the respective rotations of the rotor and the rotatable shutter.
