Abstract (en)

[origin: US4743182A] A rotating piston compressor includes a cylinder having a first given diameter, a thin-walled, radially-resilient piston with a circular cross section and a second given diameter being disposed in the piston, a radial support for the piston in the form of a rotation-symmetrical thin-walled shell formed of permanently elastic material having one end connected to the piston and another end, a body with a circular periphery holding the other end of the shell, and a drive shaft connected to the body for moving the piston with an eccentricity being larger than one half of the difference between the first and second given diameters.
