のレリース作用を可能としている。This release valve device 13 has a port 14 bored in the side wall of the cylinder 11 to communicate with the cylinder chamber 11a, and a valve chamber 15 provided in communication with the port 14. The valve chamber 15 is connected to the port 1 on the side wall of the cylinder 11.
4, and a disc-shaped release valve 16 is disposed inside. This release valve 16 is
The refrigerant is pressed against the outlet of the port 14 by the spring 17 from the outflow side, and when the pressure inside the cylinder chamber 11a exceeds a predetermined pressure, the refrigerant overcomes the pressing force of the spring 17 and moves inside the valve chamber 15. Bows 1 to 14 are opened to enable the release action of compressed refrigerant.
符号１８はスプリング１７を弁室１５内で保持するサポ

状態によりレリース弁１６が傾いた場合には、ぞの傾い
た状態のままで弁室１５内を往復移動することになる。In the release valve device 13 having such a structure, the release valve 16 is pushed by the compressed refrigerant and can move freely within the valve chamber 15, so the release valve 16 is moved depending on the state of the compressed refrigerant to be discharged. If it is tilted, it will reciprocate within the valve chamber 15 while remaining in the tilted state.

円筒部３５が、それぞれ形成されている。A valve seat member 33 having a flat surface 32 constituting a valve seat 32a is inserted into the valve chamber 26. The valve seat member 33 is
An arcuate surface 34 that contacts the cylindrical surface of the valve chamber 26 is formed on the opposite side from the flat surface 32, and a fixing cylindrical portion 35 that fits with the cylindrical surface of the valve chamber 26 is formed on the lower part.

ずくしである。The valve seat 32a is formed to protrude in a ring shape from the flat surface 32, and is processed into a flat surface. On the flat surface 32,
A flexible reed valve (straight valve) 37 whose upper portion is fixed by a rivet 36 is attached so as to be able to abut against the valve seat 32a, and this reed valve 37 has an upper 15 portion fixed to the rivet 36. The opening operation of the reed valve 37 is limited by backing up using a fixed intervening member 38. A small hole 38a is formed in the lower part of the valve holding member 38 to apply back pressure when the reed valve 37 is opened.

The valve seat member 33 whose upper part is fixed to the flat surface 32 is inserted into the valve chamber 26 from above the cylinder 21 and fixed by fitting the cylindrical part 35 into the valve chamber 26. be done. Furthermore, the upper end of the reed valve 37 attached to the valve seat member 33 is disposed at a position that projects upward from the upper end surface of the cylinder 21 when installed, thereby reducing stress and
Valve settings such as spring constant! + Efforts are being made to improve margin. A seal cap 39 is attached to the protruding upper part of the valve seat member 33.
is removed while being press-fitted into the main bearing 22, and the valve chamber 26 and the inside Y' of the casing 29 are sealed.
次にこのような構成からなる本実施例の作用ならびに効

たがって従来のフリー弁のように、弁室２６内の特定部
分に当って局部的な摩耗を生じさせることがない。When the valve device according to this embodiment is used as a release valve device, at the time of release, the lower part of the reed valve 37 is squeezed by the pressure from the cylinder chamber 24 side, the reed valve 37 is separated from the valve seat 32a, and the port 1 ~ Cylinder chamber 2 through 25
A portion of the compressed refrigerant flows out from 4. In this case, since the upper part of the reed valve 37 is fixed to the valve seat member 33, the reed valve 37 performs a predetermined operation without being affected by the state of the refrigerant flowing out. Therefore, unlike conventional free valves, localized wear does not occur in a specific portion within the valve chamber 26.
また、弁座３２ａがシリンダ２１の側壁に直接設けられ
ていないので、リード弁３７が弁座３２ａを打撃する音
が圧縮機外へ伝わりにクク、圧縮機の運転騒音を低下さ
せることができる。Further, since the valve seat 32a is not provided directly on the side wall of the cylinder 21, the sound of the reed valve 37 hitting the valve seat 32a is transmitted to the outside of the compressor, thereby reducing the operating noise of the compressor.
本実施例においては、弁座３２ａがシリンダ２１とは別

た、リード弁３７が弁室２６内を往復移動しないので、
弁室２６の内壁の仕上げ精度はそれ程高くなくてよく、
弁室２６の加工が容易である。In this embodiment, although the valve seat 32a is machined into a valve seat member 33 which is a separate member from the cylinder 21, since it is formed on a flat surface, it is machined directly onto the cylinder 21. It is easier to process and has better accuracy than. Furthermore, since the reed valve 37 does not move back and forth within the valve chamber 26,
The finishing accuracy of the inner wall of the valve chamber 26 does not need to be very high.
Processing of the valve chamber 26 is easy.
なお、本実施例においては、レリース弁装置について説

。As explained above, according to the present invention, accurate valve opening/closing operations can always be obtained without abnormal wear of a specific portion of the inner wall of the valve chamber. In addition, the noise during operation can be reduced, and the valve chamber and valve seat can be easily processed.
