Abstract

A hermetic compressor has a structure where a spring reed is separated from a discharge reed at its fixed end by a determined clearance and separated from it at an opening / closing section of the discharge reed by a clearance larger than that at the fixed end. This structure allows increase in distance between the discharge reed and a movable section of the spring reed at a position corresponding to the opening / closing section of the discharge reed. Therefore, the displacement range having a small spring constant can be extended at the beginning of opening of the discharge reed, so that the spring characteristic of a discharge valve device can be increased.

Description

technical field [0001] The present invention relates to a compressor used in refrigerator refrigerators and the like. Background technique [0002] As disclosed in, for example, Japanese Patent Laid-Open Publication No. H09-105383, some conventional hermetic compressors have a discharge valve arrangement that reduces loss during opening / closing of the discharge reed. To reduce noise during operation and improve energy efficiency. [0003] A conventional hermetic compressor will be described below with reference to the accompanying drawings. [0004] Figure 7 It is a sectional view of a conventional hermetic compressor. Figure 8 It is a side sectional view of a discharge valve device of a conventional hermetic compressor. Figure 9 It is an exploded view of the discharge valve device of a conventional hermetic compressor. Figure 10 is the spring characteristic diagram of a traditional hermetic compressor. [0005] exist Figure 7 , Figure 8 , Figure 9 and Figure...
