Abstract

PURPOSE:To prevent interference noise to be generated by a delivery gas and the oil in a delivery chamber to reduce noise during operation by forming an oil delivery path by means of a noise eliminating chamber cover, in which an oil drain hole is drilled, under a noise eliminating chamber and the secondary throttle section, connected to the oil drain hole, in the oil path cover. CONSTITUTION:The oil delivered from a cylinder through a delivery valve 8 enters the secondary throttle groove 19 in an oil path cover plate 17 from an oil drain hole 21 facing a delivery valve chamber 15, pushed by delivery gas pressure, and released out of the top of the groove 19. Since the groove 19 is a fine groove throttle, its function cannot be almost affected by the noise radiated from the delivery valve chamber 15. Even if the oil filled in the cylinder 3 when a rotary compressor is stopped or the oil circulating during operation is delivered, the oil will not remain in the delivery valve chamber 15 under a delivery noise-eliminating chamber 11. The oil is released rapidly through the oil drain hole 21 to the top of the groove 19 to prevent the oil from being remaining in the delivery valve chamber 15. Thus, interference noise to be generated by the delivery gas and the oil in the delivery valve chamber 15 can be prevented, and a quiet rotary compressor can be obtained.
