【考案の詳細な説明】
本考案は燃料ポンプ、圧力作用装置等に使用される舌状
チェック弁装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in tongue-shaped check valve devices used in fuel pumps, pressure-applying devices, and the like.
米国特許２９８４４６５号公報にて開示された従来の舌
状チェック弁装置においては、第１図に示されるように
、弁室２の上壁４が舌状チェック弁１の付根部１ａより
上方に向って斜めに形成されている。In the conventional tongue check valve device disclosed in U.S. Pat. No. 2,984,465, as shown in FIG. It is formed diagonally.
このような舌状チェック弁装置は、舌状チェック弁１の
開口作動時に該舌状チェック弁１自体の湾曲が小さくな
り、耐久性が良好となる。In such a tongue-shaped check valve device, the curvature of the tongue-shaped check valve 1 itself is reduced when the tongue-shaped check valve 1 is opened, and its durability is improved.
しかしながら、このようなチェック弁装置は舌状チェッ
ク弁１が開口作動時に弁室上壁４に密着し易くなり、通
路６の閉塞作動が確実に行なわれず、該舌状チェック弁
１の応答性が悪くなる欠点があった。However, in such a check valve device, the tongue-shaped check valve 1 tends to come into close contact with the upper wall 4 of the valve chamber during the opening operation, and the passage 6 cannot be reliably closed, and the responsiveness of the tongue-shaped check valve 1 is reduced. There were drawbacks that made it worse.
本考案は上記の欠点に鑑みなされたもので、チェック弁
の応答性が良好で、耐久性の良い舌状チェック弁装置を
得ることを目的とする。The present invention was devised in view of the above-mentioned drawbacks, and an object of the present invention is to obtain a tongue-shaped check valve device with good check valve responsiveness and good durability.
以下本考案の実施例を第２図に基づいて説明する。An embodiment of the present invention will be described below based on FIG. 2.
従来と同一部分には同一符号を付す。５は弁室２の上壁

通路６開目時に該舌状チェック弁１が前記突起５に係合
することにより、該舌状チェック弁１と弁室上壁４との
間に隙間が形成されるようになっている。The same parts as before are given the same reference numerals. Reference numeral 5 denotes a projection provided on a part of the upper wall 4 of the valve chamber 2, and when the tongue-shaped check valve 1 engages with the projection 5 when the passage 6 of the tongue-shaped check valve 1 is opened, the tongue is closed. A gap is formed between the check valve 1 and the valve chamber upper wall 4.
３は弁座面、Ａは弁座面３を構成する部材、Ｂは弁室上
壁４を構成する部材である。3 is a valve seat surface, A is a member constituting the valve seat surface 3, and B is a member constituting the valve chamber upper wall 4.
上記の如く構成した本考案によれば、開口作動時の舌状
チェック弁１が、弁室上壁４に接触する前に突起５に係
合し、前記弁室上壁４との間に隙間が形成されるため、
舌状チェック弁１が弁室上壁４に密着することがなくな
り、舌状チェック弁１の作動が確実に行なわれる。According to the present invention configured as described above, the tongue-shaped check valve 1 during the opening operation engages with the protrusion 5 before contacting the valve chamber upper wall 4, and there is a gap between the tongue-shaped check valve 1 and the valve chamber upper wall 4. is formed, so
The tongue-shaped check valve 1 no longer comes into close contact with the valve chamber upper wall 4, and the tongue-shaped check valve 1 can be operated reliably.
その結果舌状チェック弁１の応答性が良好となる。As a result, the responsiveness of the tongue check valve 1 is improved.

When the tongue-shaped check valve 1 is opened, the tongue-shaped check valve 1 engages with the projection 5, so that a gap is formed between the tongue-shaped check valve 1 and the upper wall 4 of the valve chamber. A tongue-shaped check valve device characterized by:
