Abstract
(EN)
A brake device S has a switching unit 6 having: a first pipe 7 one end of which is connected to a brake pedal B and through which air supplied from a main air tank 4 passes; a second pipe 8 one end of which is connected to the brake pedal B, through which the air is passed, and which is longer than the first pipe 7; a first partition plate 67 that partitions a first space 651 into which air flows from the first pipe 7 and a second space 652 into which air flows from the second pipe 8; and a valve 62 that opens and closes a second opening 69 that allows air flowing in from a wheel park air tank 5 to flow out to a service line 1. When the brake pedal B is stepped on: air flows in from the first pipe 7 into the first space 651, the first partition plate 67 moves, and as result, the valve 62 moves; and the valve 62 moves further as a result of air flowing in from the second pipe 8 thereby closing the second opening section 69.

Un dispositif de freinage S comprend une unité de commutation 6 doté des éléments suivants: une première conduite 7 dont une extrémité est reliée à une pédale de frein B et par laquelle passe l'air fourni par un réservoir d'air principal 4 ; une seconde conduite 8 dont une extrémité est reliée à la pédale de frein B, par laquelle passe l'air, et qui est plus longue que la première conduite 7 ; une première plaque de séparation 67 qui sépare un premier espace 651 dans lequel l'air provenant de la première conduite 7 pénètre et un second espace 652 dans lequel l'air provenant de la seconde conduite 8 pénètre ; et une soupape 62 qui ouvre et ferme une seconde ouverture 69 qui permet à l'air entrant d'un réservoir d'air de parc de stationnement de roues 5 de s'écouler vers une conduite de service 1. Lorsque l'on appuie sur la pédale de frein B : l'air entre de la première conduite 7 dans le premier espace 651, la première plaque de séparation 67 se déplace, et par conséquent, la soupape 62 se déplace ; et la soupape 62 se déplace davantage en raison de l'air qui entre à partir de la deuxième conduite 8, fermant ainsi la seconde section d'ouverture 69.

ブレーキ装置Sは、一端がブレーキペダルBに接続されており、メインエアタンク4から供給される空気を通す第1の管7と、一端がブレーキペダルBに接続されており、前記空気を通し、第1の管7よりも長い第2の管8と、第1の管7から空気が流入する第1空間651と第2の管8から空気が流入する第2空間652とを仕切る第1仕切板67と、ホイールパークエアタンク5から流入する空気をサービスライン1に流出させるための第2開口部69を開閉する弁62とを有する切替部6とを有し、ブレーキペダルBが踏まれると第1の管7から第1空間651に空気が流入して第1仕切板67が移動することで弁62が移動し、第2の管8から空気が流入することで弁62がさらに移動して第2開口部69を閉じる。
