Title:
SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JP3658831
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent invasion of abrasion powder from a circular seal to the refrigerating cycle side by providing a communication port to be provided between a fixed scroll and a support member for that on a back surface of an end plate of the fixed scroll, and a circular recessed part around the communication port at a discharge port on the lower pressure side of the circular seal part.
SOLUTION: Between a fixed scroll 11 and an upper frame 25 is sealed by a circular seal 29 around a communication part between a communication port 28 and a discharge port 15. A circular seal 41 is interposed between cylindrical slide parts 29a, 29b to which the fixed scroll 11 and the upper surface frame 25 face in such a design that a seal surface range necessary for preventing leak of high pressure refrigerant is satisfied. In addition, a circular recessed part 42 is provided on the fixed scroll 11 on the low pressure side of the circular seal 29. This may be provided on the upper frame 25, or on both of these. Abrasion powder is stored in this recessed part 42, and its move to the outer side of it is prevented, thereby jumping of it to the refrigerating cycle side can be prevented.
