る。 Further, as shown in FIG. 1, the discharge valve structure is made of a straight elastic plate, and has the valve portion 41 seated on the seat surface 6 provided on the outer periphery of the discharge port 2 on one side, and the valve portion 41 on the other side. The discharge valve 4 has a fixing part 42 that comes into contact with the fixing surface 7 at the top, and an elastic plate having substantially the same length as the discharge valve 4 and curved upward in a convex shape, and the discharge valve 4 is arranged on one side.
A pressing part 9 that presses the tip of the valve part 41 of
1 and having a fixing part 92 facing the fixing surface 7 on the other side, and a discharge valve holder 10 that is curved convexly downward and regulates the lift amount of the discharge valve 4. There is.

１は固定用のボルトである。 Therefore, when assembling the discharge valve 4, the auxiliary plate 9, and the discharge valve holder 10 to the front head 1, first place the discharge valve 4 on the bottom layer, and then place the auxiliary plate 9 on top of it. The discharge valves 4 and the auxiliary plate 9 are stacked so as to be convex upward, and are fixed to the front head 1 by pressing them with the discharge valve holder 10. Furthermore, 1
1 is a fixing bolt.

いる。 Further, either one of the facing surfaces of the discharge valve 4 and the auxiliary plate 9 is coated with a tetrafluoroethylene resin, so that there is no space between the discharge valve 4 and the auxiliary plate 9. This is to prevent excessive frictional force from acting that would impede relative motion.
以下、作用を説明する。 The action will be explained below.
圧縮要素の吸入及び圧縮行程時には、前記吐出
弁４と補助板９との前記吐出口２側に向かう弾性
力が前記圧縮室の内圧に打勝つて、前記弁部４１
は従来と同様に前記シート面６に着座している。 During the suction and compression strokes of the compression element, the elastic force of the discharge valve 4 and the auxiliary plate 9 toward the discharge port 2 overcomes the internal pressure of the compression chamber, and the valve portion 41
is seated on the seat surface 6 as in the conventional case.

押圧部９１が押上げられ、これら弁部４１及び押
圧部９１はやがて前記吐出弁押さえ１０に当接し
て、そのリフト量が規制される。 When the compression element enters the compression stroke, the gas in the compression chamber overcomes the elastic force between the discharge valve 4 and the auxiliary plate 9, and the valve portion 41 of the discharge valve 4 and the pressing portion 91 of the auxiliary plate 9 are pushed up. The valve portion 41 and the pressing portion 91 eventually come into contact with the discharge valve holder 10, and the amount of lift thereof is regulated.
さらに、吐出行程が終了すると前記吐出弁４及
び補助板９に蓄積された弾性力により、これら弁
４及び板９は高速で前記シート面６側に復動し始
める。 Further, when the discharge stroke is completed, the elastic force accumulated in the discharge valve 4 and the auxiliary plate 9 causes the valve 4 and the plate 9 to begin to move back toward the seat surface 6 at high speed.

より平行に近い状態で当接し始めるのである。
尚、第４図には従来の吐出弁４の着座開始時の弁
形状を一点鎖線で示している。 At this time, the distal end of the valve portion 41 of the discharge valve 4 is pressed toward the seat surface 6 by the pressing portion 91 of the auxiliary plate 9, so that the valve portion 41 of the discharge valve 4 is opened. When the discharge port 2 of the discharge valve 4
The degree of convex curvature toward the side becomes smaller, and the relative return speed of the distal end portion of the valve portion 41 to the base portion becomes faster than that of the conventional valve portion 41, and the seat of the valve portion 41 At the start of seating on the surface 6, as schematically shown in FIG.
The valve portion 41 begins to contact the seat surface 6 in a state that is more parallel to the seat surface 6 than in the past.
In addition, in FIG. 4, the shape of the conventional discharge valve 4 when it starts to be seated is shown by a chain line.
この結果、この着座時における前記弁部４１と
前記シート面６との接触面積が拡大し、前記吐出
弁４に加わる衝撃荷重が従来のように前記弁部４
１の付け根部分に局所的に働くのを防止できるの
である。 As a result, the contact area between the valve part 41 and the seat surface 6 when the seat is seated is expanded, and the impact load applied to the discharge valve 4 is reduced to the valve part 4 as in the conventional case.
This makes it possible to prevent localized action on the root portion of 1.
従つて、前記吐出弁４が、前記弁部４１の付け
根部分にクラツクが発生して破損する頻度を低下

る。 Therefore, the frequency with which the discharge valve 4 is damaged due to cracks occurring at the base of the valve portion 41 can be reduced, and durability can be improved.

も防止できるのである。 Moreover, the discharge valve 4 and the auxiliary plate 9 are both made of elastic plates, and the auxiliary plate 9 is curved in advance in a direction that exerts a closing force on the discharge port 2. Therefore, the overall closing speed can be significantly increased compared to the conventional method. Therefore, when this discharge valve structure is applied to a rotary compressor that rotates at high speed using an inverter, it is possible to prevent the phenomenon of closing delay, which is a defect of conventional discharge valve structures.

ある。(Effect of the invention) As described above, according to the invention, the discharge valve 4
An auxiliary plate 9 made of an elastic plate having a fixing part 92 on one end and a pressing part 91 on the other end is provided with approximately the same length as the
The auxiliary plate 9 is curved in a convex shape toward the discharge valve holder 10 of the discharge valve 4.
These discharge valves 4 and auxiliary plates 9 are stacked on the side.
and the pressing part 91 of the auxiliary plate 9 to the stationary member.
However, since the tip of the valve portion 41 of the discharge valve 4 is fixed integrally so as to be pressed toward the discharge port 2 side, the tip of the valve portion 41 of the discharge valve 4 is pressed by the pressing portion 91 of the auxiliary plate 9. is always pressed toward the discharge port 2 side, and the degree to which the valve portion 41 of the discharge valve 4 curves convexly toward the discharge port 2 side of the discharge valve 4 during the opening operation can be reduced. Since the degree of curvature of the discharge valve 4 is small even when the seat begins to sit on the seat surface 6, the valve portion 41 can be brought closer to being parallel to the seat surface 6. As a result, the contact area when the valve portion 41 starts to sit on the seat surface 6 can be expanded compared to the conventional case, and excessive local stress can be prevented from acting on the discharge valve 4. By reducing the frequency of localized cracks and damage,
The durability of the discharge valve can be improved.
