Compression bonding allows the two parts to be reseparated, facilitating repair if the valve becomes damaged.
次に添付図面を参照にして本発明の幾つかの実施例につ
いて詳細に説明する。Several embodiments of the invention will now be described in detail with reference to the accompanying drawings.
第１図に示されるように、過給ディーゼルエンジンのた

とで構成される。ディスク２は、シリンだヘッド内の弁
座（図示せず〕の円錐座面に合わされる周知の円錐緘封
面４を有する。As shown in FIG. 1, the discharge valve 1 of the invention for a supercharged diesel engine consists of two separable parts, namely:
Closure element 2 in the form of a disc and guide member 3 in the form of a stem
It consists of The disc 2 has a conventional conical sealing surface 4 which mates with the conical seating surface of a valve seat (not shown) in the cylinder head.
ディスク２は円筒形の連続的な中心孔５を有し、この孔
の中に円筒形ステム３の一方の端部が嵌合される。ステ
ム３とディスク２とは圧縮によって相互に結合される。The disc 2 has a cylindrical continuous central hole 5 into which one end of the cylindrical stem 3 fits. Stem 3 and disk 2 are connected to each other by compression.
即ち、ディスク２の温度がステム３のそれより高くされ

孔５に対して堅く圧接される。That is, the temperature of the disc 2 is made higher than that of the stem 3, the two parts are then joined, and as the disc 2 cools it shrinks onto the stem 3, thus joining the two parts with a shrink fit. be done. This shrink fit connection can also be achieved by lowering the temperature of the stem 3 by cooling, instead of heating the disc 2, and then joining the parts. When stem 3 is reheated,
It is firmly pressed against the hole 5.
ディスク２は排ガスの高温と腐食性に対し非常に犬ぎい
耐性馨有する材料で作られる。そのような材料としては

３ Ｑ Ａがある。それに対してステム３は、これに加
わる条件に応じた最適の材料で作られる。The disc 2 is made of a material that is highly resistant to the high temperatures and corrosive nature of the exhaust gases. Such materials include materials with high nickel content, such as Nimonic
There are 3 Q.A. The stem 3, on the other hand, is made of the most suitable material depending on the conditions to which it is subjected.
ディスク２とステム３との間χ圧縮接合することにより
、それら２つの部品を別々のものとし、損傷した方の部
品を父換できるようになるので、弁の修理はより容易に
行えるようになる。The chi-compression joint between disc 2 and stem 3 makes it easier to repair the valve because these two parts are separated and the damaged part can be replaced. .
第２図の実施例においては、連続的な円筒形孔５の代り

端部がｉ孔６の端面と接するので、ディスクとステム間
の接合面だけでは支持しきれない大きな軸方向方乞受け
ることができる。In the embodiment of FIG. 2, instead of a continuous cylindrical hole 5, the disc 2 is provided with a hole closed on one side, a blind hole 6. In other respects, the structure of the disk 2 and stem 3 is the same as that shown in FIG. 1, and the joining is performed by shrink fitting as in the case of FIG. Since the bottom end of the stem 3 is in contact with the end surface of the i-hole 6, it is possible to receive a large amount of axial support that cannot be supported by the joint surface between the disk and the stem alone.
第３図の実施例は、ディスク２内に嵌合されるステム３
の端部分が僅かに円錐形とされ、この円錐形端部分が、
これに合致する僅かに円錐形とされたディスク２の孔７
に嵌められる。ここでも第１図で述べたような焼成めが
行われる。The embodiment of FIG. 3 has a stem 3 fitted within the disc 2.
The end portion of is slightly conical, and this conical end portion is
A matching slightly conical hole 7 in the disc 2
be fitted into. Here, too, the firing process described in FIG. 1 is performed.
このステム３の端部分に下方向のテーパが付けられる実
施例の場合も、それに合わさるディスク２の孔７は連続
的でなしに、第２図のようなｉ孔にすることができる。Even in the case of the embodiment in which the end portion of the stem 3 is tapered downward, the hole 7 in the disc 2 that meets it may not be continuous but may be an I-hole as shown in FIG. 2.
しかしその孔７を連続孔にした場合には、孔Ｔの円錐形

のとは逆にすることもできる。即ちその円錐形部分の太
い方の端部馨ステム３の下端部にもってくることができ
る。However, if the hole 7 is a continuous hole, the conical shape of the hole T and the conical shape of the end portion of the stem 3 can be reversed from those shown in FIG. That is, the thicker end of the conical portion can be brought to the lower end of the stem 3.

分岐されてステム３の環状溝１１に接成す乙。In FIG. 4, the disk 2 has the same structure as in FIG. That is, it has 5 continuous cylindrical holes. However, the end of the stem 3 that fits into this hole 5 has a central duct 8, the lower end of which is threaded at 9 and can be connected to a hydraulic medium supply system. . Two or more radial holes 10 are branched from near the upper end of the duct 8 and connected to the annular groove 11 of the stem 3.

に連続孔にも盲孔にもすることができる。As shown in Figure 4, f, F! Instead of feeding the Of medium from below, it can also be fed from above between the contact surfaces of the disk 2 and the stem 3, as shown in FIG. For this purpose, a duct 12 is formed in the center of the stem 3, and the upper end (not shown) of this duct is provided with a thread for connection to a hydraulic medium supply system.From the lower end of the duct 12 two or more The radial duct 13 of is branched off and continues into an annular groove 14 on the outer surface of the stem part, which fits into the hole 15V3 of the disc 2.The stem part also has a slight conical shape such that the free end of the stem 3 is thicker. The hole 15 in the disc 2 is also made into a matching conical shape.The hole 1
The conical shape of 5 and the conical shape of the end portion of the stem 3 may be reversed, and the hole 15 may be a continuous hole or a blind hole as shown in FIGS. 6 and 2. .

うにしてもよい。The embodiment of FIG. 6 is a cooled valve, in which the stem 3 is provided with two axially parallel ducts 16 and 17, the former for example for supplying coolant and the latter for coolant supply. Used for discharge. Disk 2 has a concentric cavity 18'a'! The lower end of the stem 3 protrudes into this. The ducts 16 and 17 have transverse holes 19 and 20 opening into the cavity 18 for supplying and discharging coolant to the cavity 18. Further transverse holes 21 and 22 extend from the ducts 16 and 17 to an annular groove 23 provided in the outer surface of the stem section between the upper end of the disc 2 and the cavity 18. These transverse holes 21 and 22 are for a hydraulic medium supply hole between the cylindrical contact surfaces of the disc 2 and the stem 3 for assembly and disassembly of the valve. two ducts 16 and 1
7 may both be connected to a hydraulic medium supply, or alternatively only one may be connected and the other may be sealed with a plug.
