Claims

[Claims for Utility Model Registration] (1) A roller 7 is installed inside the cylinder 6 so that it can rotate freely, and a blade 8 that contacts the roller 7 is supported so that it can freely reciprocate. In a rotary compressor that includes a blade spring 9 on the back side that presses the blade 8 toward the roller 7, the blade 8 is installed on the back side of the blade 8.
An auxiliary spring 10 is provided which urges the blade 8 toward the roller 7 side and prevents the blade 8 from separating from the roller 7. A rotary compressor, characterized in that the distance Ld is set shorter than the distance Ld between the roller 7 and the back contact end P of the blade 8 when the roller 7 is located at the bottom dead center. (2) The free length Lo of the auxiliary spring 10 is determined between the non-blade side restraining end S of the auxiliary spring 10 and the back side abutting end P of the blade 8 when the roller 7 is located at the top dead center. The rotary compressor according to claim 1, wherein the length is set to be approximately equal to the distance Lu. (3) The free length Lo of the auxiliary spring 10 is calculated from the non-blade side restrained end S of the auxiliary spring 10 to the back side of the blade 8 when the roller 7 is located between the top dead center and the bottom dead center. The rotary compressor according to claim 1, wherein the length is set to be approximately equal to the distance Lm between the rotary compressor and the abutting end P.
