Abstract
An oil circulation structure for a linear compressor and a method of the same are disclosed. The oil circulation structure includes an exhaust portion oil circulation path in which an oil is circulated at an exhaust portion at which a gas compression and exhausting operation is performed, for thereby cooling the exhaust portion, a cylinder cooling oil circulation path communicating with one side of the exhaust portion oil circulation path for cooling an outer surface of the cylinder, a friction portion cooling oil circulation path for cooling a friction portion between the cylinder and the piston, a plurality of oil through holes formed at the cylinder for communicating the cylinder cooling oil circulation path with the friction portion cooling oil circulation path, an oil supply path for supplying the oil pumped from the oil supply unit into the cylinder cooling oil circulation path, and an oil exhaust hole formed at the frame and communicating another side of the exhaust portion oil circulation path for thereby returning the oil into the hermetic container, for thereby increasing a cooling effect of a cylinder and exhaust portion and a lubricating performance of a friction portio…
