Patent number: 11286919Abstract: Variable displacement swash plate type compressor includes casing, rotating shaft, swash plate, piston, and inclination adjustment mechanism with first flow path connecting discharge chamber with crankcase and second flow path connecting crankcase with suction chamber to adjust inclination angle of the swash plate. An orifice hole decompressing fluid passing through the second flow path is formed in the second flow path. An orifice control mechanism controlling effective flow cross-sectional area of the orifice hole is formed on the second flow path. The orifice hole and control mechanism are formed to increase differential pressure in the crankcase and suction chamber, the effective flow cross-sectional area increases, and with further differential pressure increase it becomes a second area larger than zero and less than the first area. Achieved is rapid control of refrigerant discharge amount and prevention of reduction in compressor efficiency with reduction of time to switch to the maximum mode.Type: GrantFiled: July 19, 2019Date of Patent: March 29, 2022Assignee: Hanon SystemsInventor: Se Young Song

Publication number: 20200400133Abstract: A control valve and a variable capacity compressor which are capable of preventing an unnecessary loss of control gas to improve efficiency of the compressor reduces loss of control gas by eliminating a fixed orifice hole in an existing valve assembly and forming it in a control valve or a passage connecting the control valve and a crank chamber. The size of the fixed orifice hole is variable (which is possible by selectively opening and closing a plurality of holes) depending on the operation of the compressor. On the other hand, forming the fixed orifice hole in the passage connecting the control valve and the crank chamber causes the loss of control gas to be reduced because the fixed orifice hole can be machined to a smaller size compared to an existing orifice hole, the minimum size of which is limited due to difficulty of machining.Type: ApplicationFiled: May 28, 2018Publication date: December 24, 2020Inventors: Yeol Woo SUNG, Se Young SONG
