Oil supplying mechanism, and horizontal compressor having same

Disclosed are an oil supplying mechanism, and a horizontal compressor having same. Disclosed is an oil supply mechanism for a horizontal compressor, the horizontal compressor including a housing, a motor, a rotating shaft driven by the motor, and a bearing pedestal supporting the rotating shaft. The oil supply mechanism includes a separating member, the separating member being in the form of a ring having a central hole for allowing the bearing pedestal to pass therethrough, and the separating member being configured to separate the housing into an oil storage chamber and a motor chamber with the motor provided therein. The separating member is constructed to have an annular groove opening into the oil storage chamber. The oil supply mechanism and the horizontal compressor having the oil supply mechanism can reduce or minimize free space in the motor chamber and/or facilitate a quality inspection on the structure of a pump.
