AI Technical Summary

Problems solved by technology

However, because their parts are in sliding contact and generally have high relative velocities, frictional losses are high
This limits their efficiency and reliability
[0008] In rotary vane compressors, the rotor and blade tips rub against the inside of the cylinder at high speeds, resulting in large frictional losses
Similarly, in a rolling piston compressor, the rolling piston rubs against the eccentric and the inside of the cylinder, resulting in a large frictional loss

Embodiment Construction

[0044] refer to Figures 1 to 4 , which shows a rotary vane compressor 10 having blades 12 , a rotor 14 and a cylinder 16 . The blades 12 are rigidly fixed to or integral with the rotor 14 . One advantage of this is reduced part count. Blades 12 may be manufactured together with rotor 14 if desired. The vanes 12 engage into blind slots 18 in the cylinder 16 . The vane 12 is positioned within the blind slot 18 such that it is slidably and pivotally fitted in the slot 18 and is capable of simultaneous sliding and pivotal movement. Both the blades 12 and the rotor 14 are housed in a cylinder 16 . The heads 20 of the blades 12 are rigidly connected to or integral with an outer surface 22 of the rotor 14 . The slot 18 is located in the inner surface 23 of the side wall 24 of the cylinder 16 , which is cylindrical and has a larger diameter than the rotor 14 . This allows the vane 12 to be securely mounted on the cylinder 16 .

Abstract

The invention relates to a rotary vane type compressor. The rotary vane type compressor comprises an air cylinder, a rotor and a blade; the air cylinder is provided with an air cylinder longitudinal spin axis; the rotor is installed in the air cylinder and provided with a rotor longitudinal spin axis, and the rotor longitudinal spin axis and the air cylinder longitudinal spin axis are spaced so that the rotor and the air cylinder can do relative motion; the blade is connected into a narrow groove in an operated manner so that the air cylinder and the rotor can rotate together; and the blade is installed in the narrow groove and has two degree-of-freedom motions relative to the narrow groove so that the rotor and the air cylinder can rotate together.
