LOAD DECREASED AND COMPRESSIBILITY IMPROVED VANE PUMP

摘要

PURPOSE: A vane pump which load is reduced and compressibility is improved is provided to improve compressibility by maintaining a closed contact with an inner surface of a compression room because load on a vane is reduced by moving one or more integrated vanes installed in a diametric direction of a rotator are moved. CONSTITUTION: A vane pump which load is reduced and compressibility is improved comprises one or more vanes(40). One or more vanes are installed in a diametric direction passing through a rotary center in a rotator(30). The vane is generates a volume variation of a compression chamber(23), thereby suctioning and compressing a fluid. The vane comprises a pair of vane blade units(41) and a blade connection unit(42). The pair of vane blade units contacts with the inner circumference of the compression chamber. The blade connection unit connects the pair of vane blade units to be integrated. The pair of vane blade units is installed in a vane sliding groove(31).
