General
CompressorThe vane rotor type compressor turns around the center axis of the elliptical cylinder, and the vanes, with their ends in contact with the inside wall of the cylinder, move up and down the rotor grooves. The vanes are positioned around the rotor, each equally spaced apart from another. Both sides of the cylinder are sealed by side blocks. The space, enclosed by the neighboring vanes, two side blocks, outer circumference of the rotor and inside wall of the cylinder, becomes smaller as the rotor turns, thereby compressing the internal gas. When the end of a vane sliding on the inside wall of the cylinder goes past the suction port, the vane closes the suction port. The compression stroke at the position. When the gas ahead of the vane is compressed and discharged through the discharge valve, the next vane is already on the suction stroke. Since suction and compression of the gas are separately performed in this manner, the compressed gas left behind in the discharge port never returns to the suction port. Since no suction valve is required, there is no loss caused by a suction valve. (A high pressure trigger valve provided on the rear head to apply a pressure to the back plane of vane.)
