Rolling rotor expansible chamber machine with rolling seal cylinder

A rolling rotor machine comprising:

• (a) a housing having a cylindrical interior and an outwardly extending seal chamber parallel to the cylinder axis at one portion of the cylinder periphery and plates at each end of the cylinder, said housing having an inlet port and outlet port;
• (b) a cylindrical rotor piston having a diameter less than the interior diameter of the housing;
• (c) means for rolling said piston around the interior of the housing;
• (d) a rolling seal cylinder disposed in said seal chamber and rolling on the rotor and against the interior of the seal chamber to seal the inlet from the outlet, said rolling seal having a diameter with respect to the housing seal chamber so that it can retreat into the seal chamber when the piston is rolling in the region of the seal chamber, said seal cylinder separating the inlet and outlet ports to thereby define working spaces between the rotor and the housing;
• (e) a wheel secured to each end of the rotor piston;
• (f) and a bridge formed on each end of the housing in the region of the seal chamber, each in line with its respective wheel, so that the wheels will ride on the bridges to prevent the rotor piston from entering the seal chamber.
