Abstract

로타리 압축기는 흡입구(52) 및 토출구(53)가 개방되는 실린더실(51)을 가진 실린더(5), 구동축(3)의 편심부(31)에 삽입되어 상기 실린더실(51)내에 내장되는 로울러(7), 상기 실린더실(51)의 내부를 상기 흡입구(52)로 통하는 저압실(X)과 상기 토출구(53)로 통하는 고압실(Y)로 구획하는 블레이드(7)를 포함한다. 상기 흡입구(52)가 형성된 실린더실(51)의 내주면의 위치에서 접선에 수직한 법선(C)에 대해 블레이드(9)를 향해 경사지도록 상기 흡입구(52)가 형성된다. 이러한 구성으로써, 가스유체가 흡입구(52)에서 실린더실(51)의 저압실(X)로 도입될때 유동저항이 감소됨으로써, 저압실(X)에서의 흡입가스의 압력손실이 감소될 수 있다.The rotary compressor is inserted into the cylinder 5 having the cylinder chamber 51 in which the inlet 52 and the discharge port 53 are opened, and the eccentric portion 31 of the drive shaft 3 and embedded in the cylinder chamber 51. (7) and the blade 7 which divides the inside of the cylinder chamber 51 into the low pressure chamber X which communicates with the said inlet port 52, and the high pressure chamber Y which communicates with the said discharge port 53. The suction port 52 is formed to be inclined toward the blade 9 with respect to the normal line C perpendicular to the tangent at the position of the inner circumferential surface of the cylinder chamber 51 in which the suction port 52 is formed. With this configuration, the flow resistance is reduced when the gas fluid is introduced into the low pressure chamber X of the cylinder chamber 51 from the suction port 52, so that the pressure loss of the suction gas in the low pressure chamber X can be reduced.
