Abstract:
A compressor comprising:a cylinder block assembly having at least one compression chamber; a fluid compressing member housed in said compression chamber for compressing a fluid; at least one covering member connected to one end of said cylinder block assembly to cover said compression chamber and define a discharge chamber therein for receiving a fluid compressed by said fluid compressing member; a valve plate provided between said covering member and said one end of said cylinder block assembly and having at least one discharge port through which the fluid compressed by said fluid compressing member is discharged into said discharge chamber; a metal discharge valve forming plate provided between said valve plate and said covering member to form a discharge reed valve for opening and closing said discharge port; a plate-shaped metal gasket provided between said discharge valve forming plate and said covering member, a portion of said covering member forcibly engaging said plate-shaped metal gasket; a retainer formed in said metal gasket so as to have a contact portion to restrict the magnitude of opening of said discharge reed valve; wherein said covering member also defines a restricting section and a cylindrical wall defining a surface of the discharge chamber, the cylindrical wall being generally perpendicular to the plate-shaped metal gasket, the restricting section defining a continuously curved surface joining the cylindrical wall and the portion of the covering member engaging the plate-shaped gasket; and wherein said retainer slopes upwardly toward the discharge chamber beginning beneath the cylindrical wall and does not contact the restriction section, except at the time of discharge when the retainer contacts at least part of the restriction section.
