Abstract

La présente invention concerne un compresseur configuré de sorte que l'efficacité d'aspiration de réfrigérant est augmentée, l'aspiration de réfrigérant peut être effectuée de façon uniforme, et la génération de vibration et de bruit et le risque de dommages sur une soupape d'aspiration peuvent être réduits. Ce compresseur est pourvu de : une plaque de soupape 103 disposée entre un bloc-cylindre dans lequel une pluralité d'alésages de cylindre sont formés et une culasse dans laquelle une chambre d'aspiration de réfrigérant et une chambre d'évacuation de réfrigérant sont formées, la plaque de soupape 103 comportant, formés dans celui-ci, un trou d'aspiration 103a et un trou d'évacuation 103b ; et un corps de soupape d'aspiration 138a qui est formé dans une plaque de formation de corps de soupape d'aspiration 138 pour recouvrir le trou d'aspiration et le trou d'évacuation et qui ouvre et ferme le trou d'aspiration. Le corps de soupape d'aspiration est pourvu de : une section de soupape d'aspiration 138a2 pour recouvrir le trou d'aspiration ; une pièce de restriction de degré d'ouverture 138a3 qui est en contact avec une section de restriction de degré d'ouverture de soupape d'aspiration formée sur un alésage de cylindre et qui fait saillie depuis la section de soupape d'aspiration ; un trou traversant d'évacuation 138a5 en communication avec le trou d'évacuation ; un trou traversant d'aspiration 138a6 formé sur le côté de trou traversant d'évacuation de la section de soupape d'aspiration ; et une section de renforcement rigide 138a4 formée entre le trou traversant d'évacuation et le trou traversant d'aspiration.
