COMPRESSOR AND DESIGN METHOD OF THE SAME

PROBLEM TO BE SOLVED: To reduce noise resulting from resonance at a cover in a compressor which periodically compresses a fluid and discharges the fluid to a discharge space.SOLUTION: A compressor includes: a rotary shaft which is rotationally driven; a compressor body which utilizes rotation of the rotary shaft to periodically compress a fluid and discharge the fluid; and a cover 6 having a cover body 34 forming a discharge space into which the fluid discharged from the compressor body is introduced, and multiple reinforcement parts 37 which are provided on at least one of a front surface 34a and a rear surface of the cover body 34 and extend along the at least one of the front surface and the rear surface.SELECTED DRAWING: Figure 2 【課題】流体を周期的に圧縮して吐出空間に吐出する圧縮機において、カバーにおける共鳴に起因する騒音を低減する。【解決手段】回転駆動する回転軸と、回転軸の回転を用いて流体を周期的に圧縮して吐出する圧縮機本体と、圧縮機本体から吐出された流体が導入される吐出空間を形成するカバー本体３４、及び、カバー本体３４の表面３４ａ及び裏面の少なくとも一方に設けられて、表面及び裏面の少なくとも一方に沿って延びる複数の補強部３７を有するカバー６と、を備える圧縮機を提供する。【選択図】図２
