Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] like image 3 As shown, according to the preferred embodiment of the present invention, one revolution of the crankshaft 20 causes the refrigerant to be compressed and expanded twice. The cylinder device comprises a cylinder body 30 with two open ends; a pair of valve disc units 40, 50, which are arranged at both ends of the cylinder body 30; a pair of pistons 61, 62, which are arranged on the cylinder body. body 30; a piston rod 70 that reciprocates the pistons 61, 62 while maintaining them at a predetermined interval; and a discharge valve 80 that is provided between the pistons 61, 62.

[0020] The valve disc unit pair 40, 50 has valve discs 41, 51 connected to both ends of the cylinder body 30, the valve discs 41, 51 have guide holes 41b, 51b, and the piston rod 70 is slidably inserted into the guide holes 41b, 51b. The valve disks 41, 51 have refrigerant ...

Abstract

A dual cylinder apparatus for a reciprocal hermetic compressor with a cylinder body having two open ends. A pair of valve plate units are disposed at both ends of the cylinder body, and have refrigerant discharge holes formed therein. A pair of pistons are movably disposed in the cylinder body and reciprocate therein. A piston bar having one end connected to a connecting rod is slidably supported on the valve plate units and reciprocate thereon while supporting the pistons. The piston bar has a refrigerant discharge hole through which a refrigerant, located in between the pistons, is discharged outside the cylinder body. A discharge valve movably disposed between the pistons opens one gap between one of the pistons and the cylinder body and closes a second gap between the other piston and the cylinder body.

Description

technical field [0001] The invention relates to a reciprocating sealed compressor, in particular to a double cylinder device of the reciprocated sealed compressor. Background technique [0002] like figure 1 As shown, a generally reciprocating hermetic compressor comprises a motor unit 1 having a stator 2 and a rotor 4 rotatably disposed within the stator 2 ; a crankshaft 6 ; a connecting rod 8 and a cylinder arrangement 10 . [0003] A crankshaft 6 is connected to the rotor 4 and rotates therewith, and an eccentric portion 6a is formed at the lower portion of the crankshaft. The eccentric portion 6a is connected to a large diameter portion 8a formed on the end of the connecting rod 8 . The other end of the connecting rod 8 forms a small diameter portion 8b which is connected to the piston 9 . [0004] like figure 2 As shown, the cylinder device 10 includes a cylinder body 11, the piston 9 is reciprocally inserted into the cylinder body; the cylinder head 13, the cylind...
