Description
Claims (1)
- ハウジング内を前方の負圧室と後方の変圧室とに区画する可動隔壁に連結されたバルブボデーが軸孔を備えていて、この軸孔内には、前記バルブボデーに対して軸方向に進退可能な入力部材と、この入力部材の前記バルブボデーに対する進退移動に応じて前記負圧室と前記変圧室間を連通・遮断する負圧弁および前記変圧室と大気間を連通・遮断する大気弁を備えた弁機構が組み込まれるとともに、前記入力部材の先端部が後面の第1部位に係合可能で同第1部位が後方に膨出変形可能な反動部材と、この反動部材の前面に後端部にて係合し前記バルブボデーに対して軸方向に移動可能な出力部材が組付けられていて、前記入力部材が前記バルブボデーに対して軸方向に前進移動することにより、前記負圧弁が閉じて前記負圧室と前記変圧室間の連通が遮断され、前記大気弁が開いて前記変圧室と大気間が連通されて、前記出力部材に前記負圧室と前記変圧室間の差圧に応じた出力が生じ、この出力の反力が前記出力部材から前記反動部材の前面に伝達されるとともに前記反動部材の後面から前記バルブボデーと前記入力部材に伝達されるように構成されている負圧式倍力装置であって、
前記弁機構は、前記入力部材と一体的に進退可能な大気弁座と、前記バルブボデーに進退可能に組付けた負圧弁座と、前記大気弁座とにより前記大気弁を構成する大気弁部と前記負圧弁座とにより前記負圧弁を構成する負圧弁部を有する弁体を備えており、
前記反動部材は、前記出力部材に出力が生じたとき、前記第1部位と同様に後方に膨出変形する第2部位を後面に有していて、同第2部位の後方への膨出変形が前記バルブボデーに対して軸方向に進退可能に組付けた伝達部材を介して前記負圧弁座に伝達されるように構成され、
前記バルブボデーの後方復帰位置を規定するキー部材は、前記バルブボデーが後方復帰位置に復帰したとき、前記負圧弁座を前記バルブボデーに軸方向にて当接させる位置決め手段を有している
ことを特徴とする負圧式倍力装置。
