Title:
SEALED ROTARY COMPRESSOR
Document Type and Number:
Japanese Patent JPH08334096
Kind Code:
A
Abstract:

PURPOSE: To prevent reduction in compression capacity by a muffler without exerting influence on a compression space even if a part of compressed refrigerant gas remains in the muffler by arranging a noise reducing mechanism (the muffler) to corramunicate with a delivery port outside of the compression space.

CONSTITUTION: A muffler 20 is arranged in an upper surface part 7a of an upper bearing member 7 being an external part of a compression space P. The muffler 20 is provided with a delivery passage 21 whose upstream side end part 21a communicates with a delivery port 10, and is provided with a delivery port 24 which is arranged in a downstream side end part 21b of this delivery passage 21 so as to communicate with the high pressure side and has the opening area equal to the delivery port 10, and is provided with a pressure introducing part 25 formed in the middle of the delivery passage 21 between this delivery port 24 and the delivery port 10. Therefore, even if a part of compressed refrigerant gas remains in the muffler 20, since influence is not exerted on the compression space P, reduction in compression capacity by the muffler can be reliably prevented.
