An exemplary revolving vane compressor includes a cylinder having a discharge port in and through the cylinder. A rotor housed within the cylinder is eccentrically mounted relative to the cylinder. A vane is mounted in a slot in the rotor. The vane is for sliding movement relative to the rotor. The vane is securely connected to the cylinder to force the cylinder to rotate with the rotor. A pressure shell surrounds the cylinder and the rotor. Each discharge port is for discharging fluid into an enclosed volume of the pressure shell. The cylinder is held within the enclosed volume.
