Abstract

PURPOSE: To obtain a compressor of excellent durability by improving the lubrication efficiency of rotor end surfaces, a seal housing and bearing housings.
CONSTITUTION: On both end surfaces 14b of a rotor 14 provided with a suction chamber S inside, seal grooves 17a and 17b are made respectively and both grooves are connected with a passage 18, an introducing port 19 to introduce compressed fluid into the suction chamber S in the rotor 14 is provided on one side of the cylinder chamber C and passages which connect with a seal housing or bearing 11 and 12 are provided to the introducing port 19. By so constructing, the lubrication efficiency of the rotor end surfaces, seal elements and bearings can be improved and their durabilty can be improved.
