保持させるための作用を有する。Now, the material for forming the valve seat plate 21 is as follows:
Thermosetting resin such as phenolic resin, unsaturated polyester resin, polyimide, etc., stainless steel fiber several mm in length and 50 JLm in diameter with anti-corrosion effect, steel tlI that is anti-rust and treated with chromate treatment! It consists of short metal fibers such as a, glass beads with a diameter of 10 to 1100 p, and barium sulfate. The thermosetting resin accounts for 20 to 70% of the total weight of the valve seat plate 21, and the metal layer m! i is 30-60%
, glass peas 10-40%, barium sulfate 5-3
It is blended at a ratio of 0%. Further, the short metal fibers, glass beads, barium sulfate, etc. are used as fillers for the thermosetting resin, and have the effect of maintaining the strength, hardness, elasticity, etc. of the valve seat plate 21.
なお、金属短繊維に代えて、ガラス繊維や炭素繊維等の

実施例の弁座板２１には不適である。In addition, it is possible to use inorganic fibers such as glass fibers and carbon fibers instead of short metal fibers, but these may be destroyed by the molding pressure during compression molding, so the valve seat plate of this example Not suitable for 21.
次に、成形方法としては、射出成形、移送成形、圧縮成

状態に金属短繊維を充填することができる。Next, although injection molding, transfer molding, compression molding, etc. are known as molding methods, compression molding is employed as the molding means used in this embodiment. In other words, in compression molding, when introducing the material into the mold, powdered material or material that has been preformed into a predetermined shape is used.
High filler loading is possible. In addition, since pressure is applied uniformly using a male mold during molding, no local residual stress remains.Furthermore, the metal layer mm is flat against the valve seat plate and has no orientation in any direction. Therefore, in order to obtain the high elastic modulus required for the valve seat plate, the short metal fibers can be filled in the most preferable state.
これに対し、他の樹脂成形手段、例えば射出成形、移送

留応力が残りやすく、金属短繊維等の繊維状物質は配向
しやすいという不具合があり、弁座板としての局部的欠
陥や強度低下が避けられないという問題点かある。On the other hand, in other resin molding methods such as injection molding and transfer molding, the resin weight must be kept at 50% or less because the material is filled into the mold through a gate with a diameter of several mm. There is a problem in that it is difficult to fill the container with a high degree of filling. In addition, residual stress from molding pressure tends to remain near the gate opening, and fibrous substances such as short metal fibers tend to become oriented, resulting in unavoidable local defects and a decrease in strength of the valve seat plate. There is.

めることがてきる。Thus, in this embodiment, the above-mentioned material is filled into the mold and the valve seat plate 21 is formed by compression molding, so that the valve seat plate 21, the suction valve 4, and the discharge valve 7 are made of resin and metal. It is possible to reduce noise when used as a pressurizer. In addition, since the suction valve 4 is attached to the valve seat plate 21 via the spacer step 24 integrally formed with the valve seat plate 21, it is possible to prevent crevice corrosion that has conventionally occurred, and Since the spacer 5, fixing pin 12, etc. can be omitted, the number of parts can be reduced. Also,
Since the valve seat plate 21 has a low thermal conductivity, it can suppress heat conduction from the discharge chamber side of the cylinder head to the suction chamber side, thereby increasing the suction efficiency.
