Patent ID: 8905737

Claim:
A revolving vane compressor comprising: a cylinder having a cylinder longitudinal axis of rotation, a rotor mounted within the cylinder and having a rotor longitudinal axis of rotation, the rotor longitudinal axis and the cylinder longitudinal axis being spaced from each other for relative movement between the rotor and the cylinder; a vane operatively engaged in a slot for causing the cylinder and the rotor to rotate together, the vane being mounted in the slot with a two degree-of-freedom motion relative to the slot for enabling the rotor and the cylinder to rotate with each other, the slot comprising an intermediate portion forming a narrow neck, such that during the two degree-of-freedom motion of the vane relative to the slot, the vane is configured to selectively contact either side of the narrow neck depending on interaction of rotary inertia of the cylinder and gas pressure forces in the slot so as to form a fluid-tight seal, the two degree-of-freedom motion of the vane being relative to the intermediate portion of the slot forming the narrow neck.
