First Claim
Patent Images
1. A reciprocating compressor comprising:
- a cylinder having a compression space;
a piston inserted into the compression space and reciprocating relative to the cylinder;
a discharge valve configured to be attachable to and detachable from a front end surface of the cylinder and selectively opening and closing the compression space of the cylinder; and
a discharge cover having a discharge space to selectively communicate with the compression space,wherein the cylinder has a cylinder side gas flow path for guiding refrigerant discharged to the discharge space to an inner circumferential surface of the cylinder, andthe piston has a piston side gas flow path communicating with the cylinder side gas flow path to distribute and supply the refrigerant guided through the cylinder side gas flow path between the cylinder and the piston.

Abstract
A reciprocating compressor comprises a cylinder having a cylinder side gas flow path for guiding refrigerant discharged to the discharge space to an inner circumferential surface of the cylinder and a piston having a piston side gas flow path communicating with the cylinder side gas flow path to distribute and supply the refrigerant guided through the cylinder side gas flow path between the cylinder and the piston. Also, an outlet of the gas flow path is formed in the piston and an inlet of the gas flow path is formed in the cylinder.

11. A reciprocating compressor comprising:
-
a cylinder having a compression space and gas flow paths for introducing gas in the compression space to an inner circumferential surface; a piston inserted into the compression space and reciprocating relative to the cylinder; a discharge valve configured to be attachable to and detachable from a front end surface of the cylinder and selectively opening and closing the compression space of the cylinder; and a discharge cover having a discharge space to selectively communicate with the compression space, the piston comprising; a piston body having a gas guide groove having a predetermined depth formed on an outer circumferential surface; and a gas guide member inserted and coupled to the outer circumferential surface of the piston body so as to open the gas guide groove, wherein a gas communication opening is formed in the gas guide member to allow the gas flow paths of the cylinder and the gas guide groove of the piston to communicate with each other, and a bearing hole is formed at one side of the gas communication opening to allow the gas guide groove and an bearing surface between the cylinder and the piston to communicate with each other. - View Dependent Claims (12, 13, 14, 15, 16, 17)
