Abstract
騒音減衰効果をもつ流れ抵抗の低い排出空気出口偏向装置を備えた流体力工具を提供する。
【解決手段】
本流体力工具は、駆動装置と、加圧空気入口通路(12)と、排出空気出口通路(16)とを備えたハウジング(10、11)を有し、加圧空気入口通路(12)及び排出空気出口通路(16)がハウジング(10、11)を通ってのび、駆動装置と連通し、排出空気出口通路(16)が、高度に有孔な材料に形成されかつ排気騒音低減のため排出空気流れの貫流するようにした騒音減衰要素(36、37)を備え、また出口通路(16)の出口端部に取付けられた出口偏向装置(17)を有し、出口偏向装置(17)がシェル状本体(18)を備え、シェル状体(18)が、排出空気出口通路(16)に回転できるように受けられる円筒状首部分(19)、凹面状流れ案内面(28)、間に主流れ通路(31)を形成する二つの平行な内壁(30a、30b)及びそれらとシェル状体(18)との間に、主流れの両側に騒音減衰用の低速度空気流れシールドを形成する二つの補助流れ通路(32a、32b)を備えている。

Claims (6)
- ハウジング(10、11)と、駆動装置と、加圧空気入口通路(12)と、排出空気出口通路(16)とを有し、加圧空気入口通路(12)及び排出空気出口通路(16)がハウジング(10、11)内に設けられ、駆動装置と連通し、排出空気出口通路(16)が一つ以上の騒音減衰要素(36、37)を備え、またハウジング(10、11)に可動に取付けられ、排出空気出口通路(16)からの排出空気の流れを任意所望の方向に向ける出口偏向装置(17)を有する流体力工具において、
上記出口偏向装置(17)が、排出空気出口通路(16)とほぼ同軸関係に設けられた入口開口(25)及び上記入口開口(25)に対してほぼ垂直な方向に向いた出口開口(29)をもつシェル状体(18)を備え、上記シェル状体(18)を通る流れ方向に二つの平行な内壁(30a、30b)がのび、上記二つの平行な内壁(30a、30b)がそれらの間に主流れ通路(31)を形成し、そしてそれらとシェル状体(18)との間に二つの補助流れ通路(32a、32b)を形成し、補助流れ通路(32a、32b)が上記主流れ通路(31)に平行でありしかも主流れ通路(31)より狭いこと
を特徴とする流体力工具。 - 上記内壁(30a、30b)が上記シェル状体(18)の主要部分にわたってのびていることを特徴とする請求項1記載の流体力工具。
- 上記シェル状体(18)が、上記入口開口(25)を包囲しかつ上記排出空気出口通路(16)に受けられるようにされた弾性的に膨張可能な環状の首部分(19)を備え、上記首部分(19)を上記排出空気出口通路(16)に挿入した時、上記首部分(19)の弾性膨張により、上記排出空気出口通路(16)の内部周囲溝(23)とロック係合する外側肩部(22)が上記首部分(19)に形成されていることを特徴とする請求項1又は2記載の流体力工具。
- 上記首部分(19)の内側に線ばね要素(26)が取付けられ、上記首部分(19)の弾性膨張力を高め、それにより上記首部分(19)とハウジング(10、11)とのロック係合を強めるようにしたことを特徴とする請求項3記載の流体力工具。
- 上記線ばね要素(26)がほぼΩ形状であり、上記排出空気出口通路(16)における上記一つ以上の騒音減衰要素(36、37)の軸方向支持体を成していることを特徴とする請求項4記載の流体力工具。
- 上記ハウジング(10、11)がピストル形ハンドル(11)を含み、このピストル形ハンドル(11)内に上記加圧空気入口通路(12)及び上記排出空気出口通路(16)が配置され、上記出口偏向装置(17)が上記ピストル形ハンドル(11)の末端に取付けられていることを特徴とする請求項1〜5のいずれか一項記載の流体力工具。
