Abstract
A gas compressor has a housing and a rotary body within the housing. The rotary body has one or more pistons in piston chambers that are open to the outer circumferential surface. Each piston is rigidly secured to an engagement profile that extends perpendicular to the direction of the piston's travel. A stroke length control element is connected to one or more engagement profiles. As the rotary body rotates, the stroke length control element moves along the one or more engagement profiles. The stroke length of the piston is controlled by the position of the stroke length control element. The stroke length control element is biased toward an extended position buy is forced toward the central axis to shorten the stroke length of the piston upon application of a predetermined back pressure.
