Title (EN) PRESSURE BUFFERING DEVICE
(FR) DISPOSITIF D'AMORTISSEMENT DE PRESSION
(JA) 圧力緩衝装置
Abstract:
(EN) This pressure buffering device is provided with: a cylinder which houses a fluid; a piston which forms a flow path through which the fluid flows accompanying a rod moving in a prescribed direction relative to the cylinder; a valve which is elastic and which opens and closes the flow path of the piston; a movement permitting unit which permits moving the valve position between a contact position contacting the piston and a withdrawn position spaced away from the piston; a limiting unit which limits flexural deformation of the valve in the withdrawn position; and an applying unit which is elastic and applies to the valve a weight that is unequal in the circumferential direction of the valve and that is directed towards the piston.
(FR) L'invention concerne un dispositif d'amortissement de pression, lequel dispositif comprend : un cylindre qui renferme un fluide; un piston qui forme un trajet d'écoulement à travers laquelle s'écoule le fluide, accompagnant une tige se déplaçant dans une direction prescrite par rapport au cylindre; une soupape qui est élastique et qui ouvre et ferme le trajet d'écoulement du piston; une unité d'autorisation de déplacement qui autorise le déplacement de la position de soupape entre une position de contact, en contact avec le piston, et une position de retrait, écartée du piston; une unité de limitation qui limite la déformation en flexion de la soupape dans la position de retrait; et une unité d'application qui est élastique et qui applique à la soupape un poids qui est inégal dans la direction circonférentielle de la soupape et qui est dirigé vers le piston.
(JA) 圧力緩衝装置は、流体を収容するシリンダと、シリンダに対するロッドの所定方向の相対移動に伴って流体が流れる流路を形成するピストンと、弾性を有し、ピストンの流路を開閉するバルブと、ピストンに接触する接触位置とピストンから離れる離間位置との間でバルブの位置の移動を許容する移動許容部と、離間位置にてバルブの撓み変形を制限する制限部と、弾性を有し、バルブの周方向において不均等であってピストン側に向けた荷重をバルブに付与する付与部とを備える。
