Patent number: 8303263Abstract: The present invention relates to a compressor, wherein a rotary shaft 140 having a swash plate 144 coupled thereto is used to linearly reciprocate a piston 150 in a cylinder bore 134 formed in front and rear cylinder blocks 130 and 130?. The rotary shaft 140 has a flow channel 142 formed therein and inlets 142a formed to communicate with the flow channel 142. A hub 146 is formed in the swash plate 144, and a shaft hole 146a, through which the rotary shaft 140 passes, is formed in the center of the hub 146. Communication holes 146b are formed in the hub 146 to communicate with the inlets 142a of the flow channel 142. First races 148a are coupled to the hub 146. A rotary shaft hole 148d is formed in the first race 148a, which has a thickness greater in its outer peripheral portion than its inner peripheral portion.Type: GrantFiled: April 18, 2008Date of Patent: November 6, 2012Assignee: Halla Climate Control Corp.Inventors: Kweon-Soo Lim, Duck-Bin Yoon, Min-Gyu Kim, Jung-Jae Lee

Publication number: 20080302128Abstract: The present invention relates to a compressor used in an air conditioner of a vehicle. In the present invention, an oil separation chamber and a discharge chamber are formed in one side of a discharge chamber of a compressor, a cylindrical oil separation conduit is formed between the oil separation chamber and the discharge chamber. At the same time, one discharge passage is formed such that refrigerant supplied from the front and rear discharge chambers is collected and oil is separated from the refrigerant, so that the oil is separated from the compressed refrigerant and returns to a swash plate chamber, thereby improving lubricity in the swash plate chamber.Type: ApplicationFiled: June 6, 2008Publication date: December 11, 2008Inventors: Tae Young PARK, Duck Bin Yoon, Kweon Soo Lim, Min Gyu Kim, Jung Jae Lee
