ABSTRACT:
A rotary gas compressor and vacuum pump apparatus which utilizes a central rotor with a slot formed therein to slidably receive a piston eccentrically connected onto a disk which covers the slot to form a cylinder is disclosed. The distance between the rotor axis and disk axis is equal to the distance between the disk axis and the off-center shaft axis, with all axes being parallel. Upon rotation of the disk, the rotor rotates at one-half the rotational velocity of the disk causing the piston to reciprocate in the cylinder, with gas flowing into the increasing cylinder volume and being compressed and discharged in the decreasing cylinder volume. This cyclic process continues with continued rotation of the central rotor.
