Title (EN) SHOCK ABSORBER
(FR) AMORTISSEUR
(JA) 緩衝器
Abstract:
(EN) Provided is a shock absorber that prevents a failure when the thrust force of a solenoid is relatively small. This shock absorber is provided with: a chamber that is provided on one side of a valve body and that communicates with one cylinder-side chamber and the other cylinder-side chamber; a first communication path that allows communication between the chamber and the one cylinder-side chamber; and a second communication path that allows communication between the chamber and the other cylinder-side chamber. The first communication path is provided with a first orifice and the second communication path is provided with a second orifice.
(FR) L'invention concerne un amortisseur qui empêche une défaillance lorsque la force de poussée d'un solénoïde est relativement faible. Cet amortisseur est pourvu : d'une chambre qui est disposée sur un côté d'un corps de soupape et qui communique avec une chambre côté cylindre et une autre chambre côté cylindre ; un premier trajet de communication qui permet la communication entre la chambre et la chambre côté cylindre ; et un second trajet de communication qui permet la communication entre la chambre et l'autre chambre côté cylindre. Le premier trajet de communication est pourvu d'un premier orifice et le second trajet de communication est pourvu d'un second orifice.
(JA) ソレノイド推力が相対的に小さいときのフェイル落ちを防止した緩衝器を提供する。 緩衝器は、弁体の一側に設けられ、シリンダ一側室とシリンダ一他側室とに連通する室と、室とシリンダ一側室とを連通させる第1連通路と、室とシリンダ他側室とを連通させる第2連通路と、を備える。第1連通路は第1オリフィスを備え、第2連通路は第2オリフィスを備える。
