Title: Air compressor

Abstract: A small high speed direct connected motor compressor has a unitary piston and piston rod whereby the piston wobbles in the cylinder as the crank shaft rotates. The wobbling piston is sealed to the cylinder by a flanged disk of Teflon which forms both a seal and mechanical guide for the piston and which runs without lubrication in contact with a low-friction, surface-coated cylinder of high heat conductivity. The circular rim of the Teflon cup is warped from circular outline to elliptical outline twice per revolution while maintaining its seal with the walls of the cylinder. The structure involves small clearance spaces with consequent good efficiency.
