an off-center rotor having one or more radial or offset vanes sliding within slots with a spring force directed outwards;
a cylindrical casing with an undercut to make a contact sealing area with the off-center rotor;
intake and discharge ports with inner slot feed and exit extensions;
a sealed undercut between the casing and the rotor to seal between intake and discharge ports; and
a pivoted shoe that seals with the casing, wherein a rotor cylindrical body runs within the casing undercut and the pivoted shoe hovers over the casing undercut; and
