Abstract
PURPOSE: To prevent the inside surface of a casing from rusting, by coating the inside surface with a high-molecular substance.
CONSTITUTION: A chamber 6 on the side of a suction port and another chamber 7 on the side of an exhaust port are divided from each other by a check valve 10 having reads 13, which are provided on one side of a valve body 11 having a gas hole 12 to open or close the hole. The inside surface of a steel sheet casing 1 is coated with synthetic resin or rubber. Alkyd resin, acrylonitrile-butadiene copolymer, chlorosulfonated polyethylene, silicone rubber or the like is excellent as the coating material. One of said substances is used to coat the inside surface or two or more of the substances are mixed with each other to coat the surface. The single substance or the mixture is used in the form of a liquid, emulsion or solvent of purity in 100%. The material is coated by dipping, spraying, brushing or the like so that the thickness of the coating film is set at about 30W150μ. The coating film is thermally hardened if necessary. As a result, an enough anti-rusting property is attained and the contact parts of the casing and the check valve are kept hermetic to each other.
