Title:
VARIABLE FACULTY TYPE ROTARY COMPRESSOR
Document Type and Number:
Japanese Patent JPS6245990
Kind Code:
A
Abstract:

PURPOSE: To reduce noise by controlling the operation of the second blade and using the second blade when a compressor operates with the max. faculty and using the second blade having a release hole when the faculty is variable.

CONSTITUTION: When a compressor operates with the max. faculty, the second blade 9b is press-attached onto a roller 1, and closes the release hole 11 of the first blade 9a. When the faculty of the compressor can be varied, a heater 2 conducts, and the second blade 9b is accommodated into a blade groove 8, and only the first blade 9a is press-sttached onto the roller 1. Therefore, the need of the release valve is avoided, and generation of the noise due to the release valve is prevented.
