Path, or including the horizontal path complemented each other to form to groove and forward flange wall from being arranged on cylinder wall, or including by
The horizontal path cooperatively formed to groove and the groove being arranged on cylinder wall being arranged on forward flange wall.
Formed with stage portion, the cylinder side is embedded in the stage portion for the internal face side of the forward flange, and described first
It is vertical to groove from being formed in both touching positions on the cylinder and/or the stage portion that oil circuit includes, it is described vertically to
Groove connects with the level to groove.
Also include the return line of the first oil circuit of connection and oil supply mechanism.
After such scheme, the lubrication system of linear compressor of the present invention is by between forward flange and cylinder faying face
The first oil circuit that lubricating oil can be made to be delivered to piston face from oil feed line is set, and so design can make lubricating oil enter cylinder
Between piston, the two is set to keep lubrication, dry friction generation when avoiding piston operation, so as to inhibit between piston and cylinder
Contact site temperature rise, reaches the lubricant effect of piston and cylinder, improves the performance of linear compressor.
The present invention further beneficial effect be：First oil circuit is designed as to include the level by being arranged on forward flange wall
The path complemented each other to form to groove and cylinder wall, or the level from being arranged on cylinder wall are mutual to groove and forward flange wall
The path cooperatively formed, or including horizontal horizontal to recessed on cylinder wall with being arranged to groove on forward flange wall from being arranged at
The path that groove cooperatively forms, the first oil circuit so designed while guaranteeing to enter piston face, be easy to by first oil circuit
Processing, and processing technology is simple, saves cost, it is simple and compact for structure.
The present invention further beneficial effect be：By designing the return line connected with the first oil circuit and oil supply mechanism,
It can ensure that lubricating oil can be circulated between cylinder and piston, making to remain lubrication between cylinder and piston.
