Abstract

PURPOSE:To improve the extent of compression efficiency by installing a check valve gear in a fixed scroll end plate in the midway of an oil feed passage between a compression space and a discharge chamber, and forming a valve guard of a valve body with a sintered molding member consisting of porosity. CONSTITUTION:An interval between a first compression space 39b and an oil sump 18 is interconnected by an oil feed passage consisting of a suction hole 41 of an end plate 14, a check valve gear 17 with a valve plate 42 and an injection hole 30b. A valve guard of the check valve gear 17 is composed of a porous sintered alloy molding, making gas transmittable. Therefore during operation of a compressor, a clearance among fine particles is sealed by an oil film owing to an infiltration action of lubricating oil passing through an inner wall surface of the valve guard, thus a back flow of gas is prevented from occurring and, what is more, compression efficiency is improvable.
