<P>PROBLEM TO BE SOLVED: To provide a helical type compressor capable of boosting the pressure of fluid to a required level appropriately. <P>SOLUTION: An end 23a on the discharge side of a helical blade 23 that is fitted into a helical groove 22a of a rotor 22 is connected to a connection part 23b located at a section of the blade 23 that turns back from the end 23a by about one spire (by about 360°). Further, a reed valve (check valve) is provided which allows fluids in a compression room CR3 on the discharge side surrounded by a portion of the blade 23 that continues into the end 23a and the connection part 23b, an inner circumferential surface of a cylinder 21 and an outer circumferential surface of the rotor 22 only to flow from the compression room CR3 on the discharge side through a discharge hole 21a. This allows the pressure of the fluids to be appropriately boosted to the required level in the compression room CR3 on the discharge side, and allows the fluids to be discharged from the discharge hole 21a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
