Abstract
A worm type compressor comprises a cylindrical worm provided with a plurality of spiral-like passages in its inner periphery for forming fluid sealing chambers, a rotor slidably disposed within the worm and provided with an internal fluid outlet opening for discharging a compressed fluid and a pinion gear disposed within the rotor so as to be rotated about an axis perpendicular to and away from the rotor axis while engaged with the spiral-like passages. A worm type compressor further comprises a compressed fluid escape means which is provided in each of the finishing portions of the spiral-like passages of the worm for letting the compressed fluid escape from each of the spiral-like passages in the final stage of the fluid compressing step. Fluid introduced within the worm is compressed in the fluid sealing chambers as the pinion gear rotates and the compressed fluid is discharged through an internal fluid outlet port perforated in the outer periphery of the rotor without generating abnormally high pressure or noise.
