Description
【考案の詳細な説明】 本考案は気圧倍力装置に関するものである。[Detailed explanation of the idea] The present invention relates to an air pressure booster.
従来の気圧倍力装置は、第１図に示すように、
一対のシエル１ａ，１ｂによつて内部に空間が形
成され、該シエルの内部空間は、ダイヤフラム２
と該ダイヤフラム２に取付けたバルブボデイ３と

を貫通してシエルの外部に突出すると共に気密状
態でシエル１ａ，１ｂに対し前後方向に摺動自在
に保持されている。 The conventional pressure booster, as shown in Figure 1,
A space is formed inside by the pair of shells 1a and 1b, and the inner space of the shell is formed by the diaphragm 2.
The valve body 3 attached to the diaphragm 2 defines two chambers, a front chamber 4 and a rear chamber 5. Valve body 3 is rear shell 1b
It penetrates through the shell and protrudes to the outside of the shell, and is held in an airtight manner so as to be slidable in the front-rear direction with respect to the shells 1a and 1b.
バルブボデイ３のシリンダ部３ａには、プラン
ジヤ７が嵌合し、該プランジヤ７の凹部にはロツ
ド６の先端が嵌合し、作用時に、ロツド６とプラ
ンジヤ７とバルブボデイ３とが一体となつて前方
に移動する。 A plunger 7 is fitted into the cylinder portion 3a of the valve body 3, and the tip of the rod 6 is fitted into the recessed portion of the plunger 7. During operation, the rod 6, the plunger 7, and the valve body 3 are integrally moved forward. Move to.
９はポペツトバルブで、不作動時において、ス
プリング８，８′によつて弁座３ｂに当接されて
いる。したがつて、この状態ではフロント室４と
リヤ室５とは連通していない。 Reference numeral 9 designates a poppet valve, which is brought into contact with the valve seat 3b by springs 8, 8' when not in operation. Therefore, in this state, the front chamber 4 and the rear chamber 5 are not communicating with each other.
後方のシエル１ｂの後端部には、蛇腹状のブー
ツ１０の前端部が係合し、ブーツ１０の中間部は
シエルから突出したバルブボデイ３を囲繞し、ブ
ーツ１０の後端部はリテーナ１１に係合すると共
にバルブボデイ３の筒部内側に嵌合している。 The front end of a bellows-shaped boot 10 engages with the rear end of the rear shell 1b, the middle part of the boot 10 surrounds the valve body 3 protruding from the shell, and the rear end of the boot 10 engages with a retainer 11 and fits inside the cylindrical portion of the valve body 3.
従来は以上の構成からなるものであるから、矢
印方向からの外圧Ｆが加わつたとき、ブーツ内の
Ａ部にクリアランスが大きいため、簡単に軸直角
方向に変形が生じ、リテーナから脱離してしまう
などの問題があつた。 Conventionally, the structure is as described above, so when external pressure F is applied from the direction of the arrow, the clearance in the A part inside the boot is large, so it easily deforms in the direction perpendicular to the axis and detaches from the retainer. There were problems such as.
本考案では、ブーツのバルブボデイへの取付け
部に、バルブボデイの筒部外周に対し所定隙間を
置いて略水平にのびる厚肉の規制筒部を設けるこ
とによつて、バルブボデイの筒部外周とブーツと
の間のクリアランスを可及的に小さくすることに
よつて外圧にもかかわらずブーツのリテーナから
の離脱を防止しようとするものである。 In the present invention, by providing a thick-walled regulating cylindrical part extending approximately horizontally with a predetermined gap from the outer periphery of the cylindrical part of the valve body at the attachment part of the boot to the valve body, the outer periphery of the cylindrical part of the valve body and the boot are connected. By making the clearance between the two parts as small as possible, it is intended to prevent the boot from separating from the retainer despite external pressure.
以下、本考案の実施例を第２図をもつて説明す
る。第２図ではブーツ１０のバルブボデイ３への
取付け部分のみを示しているが、その他の構成に
ついては従来の気圧倍力装置と同一であるので省
略する。 An embodiment of the present invention will be described below with reference to FIG. In FIG. 2, only the attachment portion of the boot 10 to the valve body 3 is shown, but the rest of the structure is the same as that of the conventional air pressure booster, and will therefore be omitted.
バルブボデイ３の外周にはブーツ１０の蛇腹部
が位置し、ブーツ１０のバルブボデイ３への取付
部には、バルブボデイ３の筒部内への嵌合部１０
ａと、バルブボデイ３の筒部外周に対し所定隙間

とを設けたものである。すなわち、リテーナに嵌
合した嵌合部１０ａが抜け出る方向のブーツ１０
の変形を規制するようにしたものである。 A bellows portion of the boot 10 is located on the outer periphery of the valve body 3, and a fitting portion 10 into the cylindrical portion of the valve body 3 is located at the attachment portion of the boot 10 to the valve body 3.
a, and a thick regulating cylindrical portion 10b extending substantially parallel to the outer periphery of the cylindrical portion of the valve body 3 with a predetermined gap 1 therebetween.
It has been established that That is, the boot 10 is in the direction in which the fitting portion 10a fitted to the retainer comes out.
It is designed to restrict the deformation of
本考案は前上の構成からなるものであるから、

てクリアランスが小かくかつブーツを変形して
も、ブーツの移動が規制筒部により規制されるの
で、リテーナから離脱することはない等の効果が
ある。 Since the present invention consists of the above configuration,
The fitting part where the boot is fitted to the retainer has a small clearance and the boot is deformed by external pressure at least in a direction perpendicular to the axis, for example, by pushing by hand during installation of the device of the present invention. Also, since the movement of the boot is regulated by the regulating cylinder part, there is an effect that the boot does not come off from the retainer.
