Patent ID: 7314355

Claim:
A compressor comprising: a housing including a suction chamber and a discharge chamber each defined therein, a suction port for supplying a working fluid that contains lubricating oil to the suction chamber, and a discharge port communicated with the discharge chamber; a compression unit disposed in said housing, for performing a series of processes including suction of the working fluid from the suction chamber, compression of a sucked working fluid, and discharge of a compressed working fluid into the discharge chamber; and an oil separator for separating a portion of the lubricating oil from the working fluid in the discharge chamber and then delivering the working fluid toward the discharge port while collecting separated lubricating oil, said oil separator including an oil chamber defined in said housing so that the oil chamber is positioned below the discharge chamber, for collecting the separated lubricating oil, a dividing wall disposed in the discharge chamber, for forming a separating chamber partitioned off from the discharge chamber so that the working fluid flows from the discharge chamber into the separating chamber, the separating chamber having an upper area on a first axis, a lower area extending along a second axis at an acute angle from the first axis from the upper area in a downward direction and having an inner side surface so as to provide a bottom with respect to the upper area, and at least one outlet for allowing the lower area to communicate with the oil chamber, a separating tube disposed substantially on the first axis in the upper area of the separating chamber, for causing the working fluid flowed into the separating chamber to swirl around said separating tube, and then guiding the working fluid toward the discharge port, and a return path for returning the lubricating oil in the oil chamber back to the suction chamber.
