Abstract
An oil supply apparatus of a linear compressor including an oil feeder frame having an oil cylinder, an oil suction hole communicated with the oil cylinder and an oil discharge hole; an oil cover combined to the oil feeder frame to cover the oil cylinder and having an oil suction opening selectively communicated with the oil suction hole and an oil communication space selectively communicated with the oil cylinder and the oil discharge hole; an oil piston positioned between the oil feeder frame and the oil cover, being inserted in the oil cylinder and performing a slidable reciprocal movement to suck and discharge oil; and a single oil valve positioned between the oil cover and the piston. In the apparatus, only one oil valve is used to reduce the parts in number and facilitate the assembling of the valve, and does not contact other structure during its operation of the opening and closing so that a proper amount of oil can be constantly supplied.
