Abstract | To suppress pump-up of a lash adjuster.SOLUTION: In a lash adjuster 10, a plunger 21 is stored in a body 11. A valve hole 25 communicating a storage chamber 28 which is an internal space of the plunger 21 with a filling chamber 15 which is a space between the body 11 and the plunger 21 is formed on a bottom wall 24 of the plunger 21. A first spring 51 energizing the plunger 21 to a direction to which the plunger 21 protrudes from the body 11 is formed in the filling chamber 15. A valve element 19 which can close the valve hole 25, and a first retainer 31 which stores the valve element 19 are provided in the filling chamber 15. Further, a second spring 52 energizing the valve element 19 to a direction to which the valve element 19 is separated from the valve hole 25, and a second retainer 41 which stores the second spring 52 are provided.SELECTED DRAWING: Figure 2
【課題】ラッシュアジャスタのポンプアップを抑制する。【解決手段】ラッシュアジャスタ10は、ボディ11にプランジャ21が収容されている。プランジャ21の底壁部24には、プランジャ21の内部空間である貯留室28と、ボディ11とプランジャ21との間の空間である充填室15と、を連通する弁孔25が形成されている。充填室15には、プランジャ21がボディ11から突出する方向にプランジャ21を付勢している第1スプリング51が設けられている。さらに充填室15には、弁孔25を閉塞可能な弁体19と、弁体19を収容する第1リテーナ31と、が設けられている。そして、弁体19が弁孔25から離間する方向に弁体19を付勢している第2スプリング52と、第2スプリング52を収容する第2リテーナ41と、を備えている。【選択図】図2 |
