Abstract
A compressor includes a driving motor, a centrifugation space, a discharge pipe, a rotary shaft, a compression portion, a pump assembly, and an oil pickup. The centrifugation space is defined inside a case by a downstream side of the driving motor and the case, and enables centrifugation of a compressed refrigerant and a lubricant oil. The discharge pipe can discharge the refrigerant from the centrifugation space outside the case. The rotary shaft is coupled to a rotor of the driving motor and defines an oil supply path. The compression portion is provided at an upstream side of the driving motor and can compress the refrigerant as the rotary shaft rotates. The pump assembly is provided below the rotary shaft and can pump oil as rotated with the rotary shaft. The oil pickup defines an oil supply path between the pump assembly and a low oil space formed inside the case.
