Title (EN) HYDRAULIC AUTOMATIC TENSIONER
(FR) TENDEUR AUTOMATIQUE HYDRAULIQUE
(JA) 油圧式オートテンショナ
Abstract:
(EN) Oil within a pressure chamber (15) is caused to leak to a reservoir chamber (24) through a first leakage gap (31) during normal operation of an engine. When starting the engine by means of a starter generator, a plunger (28) is lifted by pressure within the pressure chamber (15) to cause a second check valve (35), which is provided between the plunger (28) and a rod (14), to close the first leakage gap (31), thereby causing the oil within the pressure chamber (15) to leak to the reservoir chamber (24) through a second leakage gap (32) having high flow passage resistance.
(FR) De l'huile à l'intérieur d'une chambre de pression (15) est amenée à s'écouler vers une chambre de réservoir (24) à travers un premier espace de fuite (31) au cours du fonctionnement normal d'un moteur. Lors du démarrage du moteur au moyen d'un générateur-démarreur, un plongeur (28) est soulevé par la pression à l'intérieur de la chambre de pression (15) de sorte à amener une seconde soupape de non-retour (35), qui est agencée entre le plongeur (28) et une tige (14), à fermer le premier espace de fuite (31), amenant ainsi l'huile à l'intérieur de la chambre de pression (15) à s'écouler vers la chambre de réservoir (24) à travers un second espace de fuite (32) présentant une grande résistance au passage d'écoulement.
(JA) エンジンの通常運転時、圧力室(15)内のオイルを第1リーク隙間(31)からリザーバ室(24)にリークさせる。スタータ・ジェネレータによるエンジンの始動時、圧力室(15)内の圧力によりプランジャ(28)を上昇させて、そのプランジャ(28)とロッド(14)の相互間に設けられた第2チェックバルブ(35)により第1リーク隙間(31)を閉鎖し、圧力室(15)内のオイルを流路抵抗の大きな第2リーク隙間(32)からリザーバ室(24)にリークさせる。
