<p>A rotary compressor (10) with a supercharge port including a compressor cylinder (12); a housing (14, 16) for forming a compression chamber (18) with said compressor cylinder; an eccentric rotarymember (20) in the chamber for defining a compression volume and for drawing in to the volume through a suction port (30) a fluid to be compressed and discharging from the volume through a discharge port (32) the compressed fluid; an oscillating vane (34) extending into the chamber and bearing on the rotary member between the suction and discharge ports for separating the volume into intake (38) and compression (40) zones; and a supercharge port (50) in the compression zone for injecting at an intermediate pressure between that of the fluid at the suction port and the fluid at the discharge port a second charge of fluid to be compressed together with the fluid received from the suction port.</p> |
