CONTROL VALVE OF VARIABLE TYPE RECIPROCATING COMPRESSOR

摘要

A control valve of a variable reciprocating compressor is provided to reduce the number of components and improve durability of the same by integrally forming a needle for opening and closing a hollow hole, and allowing the needle to be stably located in a bellows assembly. A control valve of a variable reciprocating compressor comprises a body(100b), a bellows assembly(200b), a cylinder(300b) and an integral needle(400). The body becomes a main flow path, and forms a communication hole(110b) in one side. The bellows assembly forms a mounting part(250) in an uppermost end, located in a bottom surface of the inside of the body, and is shrank/relaxed by pressure of fluid running through the communication hole. The cylinder forms a hollow hole(311b) for opening and closing in one side, equipped with passage(312b) penetrating the inside and coupled to an inner circumferential surface of an upper end of the body. The integral needle has on end received in the mounting part, and is orthogonally arranged to penetrate the passage so as to open and close the hollow hole by up-and-down movement of the bellows assembly.
