STRUCTURE FOR DISCHARGING GAS OF SMALL TYPE RECIPROCATING COMPRESSOR

摘要

PURPOSE: A structure for discharging gas of a small type reciprocating compressor is provided to improve responsiveness of a valve. CONSTITUTION: A structure includes a discharge channel(F) comprising a first hole(65), a conical hole(66) and a second hole(67) with different inner diameters successively formed on one side of a frame(60) having a cylinder penetrating hole(61) in which gas is compressed so as to have a stepped surface; an inertia valve(110) having a sealing surface contacting with the stepped surface of the discharge channel, and inserted to the discharge channel to be moved by difference of pressure; and a discharge tube(120) having a discharge hole(122) formed therein to penetrate, and a stopper part(123) placed on one end thereof to limit movement of the inertia valve, and joined to the discharge channel of the frame. The inertia valve is moved by difference of pressure between end surfaces of a first piston(40) and a second piston(50) and a compression space formed by the cylinder penetrating hole to open and close the discharge channel.
