Abstract
The present invention discloses an oil supply valve assembly of a linear compressor including a shell, the oil being stored at the lower portion of the shell, a cylinder disposed in the shell, a piston disposed in the cylinder, a main body frame to which the cylinder is fixed, and a linear motor connected to the piston, for driving the piston, comprising: a passage formed in the main body frame, for supplying the oil to a gap between the cylinder and the piston; an oil valve being coupled to the main body frame to communicate with the passage, and including an oil suction valve and an oil discharge valve; and an oil cover coupled to overlap with the oil valve and communicate with the passage of the main body frame. By this configuration, the manufacturing process of the oil supply valve assembly is simplified and mis-assembly of the components is prevented by reducing the number of the components.
