Abstract
(EN)
In a brake valve device (100), an adjustment mechanism (102) for adjusting the set pressure of a relief valve (105) has: a single free piston (122) which slides within a sleeve (121) according to pressure in a pair of main passages; and a pair of check valves (123) which permits a flow from the outside of the sleeve (121) into the sleeve (121) and blocks a reverse flow. The adjustment mechanism (102) is configured so that, when the free piston (122) is disposed at one end of the sleeve (121), one of a pair of openings (126) which connects the inside and outside of the sleeve (121) is closed, the other is opened, and the free piston (122) moves from the one end to the other end of the sleeve (121), causing the area of opening of the other of the pair of openings (126) to decrease.

Dans un dispositif de soupape de frein (100), un mécanisme de réglage (102) destiné à régler la pression de consigne d'une soupape de détente (105) comprend : un unique piston libre (122) qui coulisse à l'intérieur d'un manchon (121) en fonction de la pression dans une paire de passages principaux ; et une paire de clapets anti-retour (123) qui permettent un écoulement depuis l'extérieur du manchon (121) dans le manchon (121) et bloquent un écoulement inverse. Le mécanisme de réglage (102) est conçu de telle sorte que, lorsque le piston libre (122) est disposé au niveau d'une extrémité du manchon (121), l'une d'une paire d'ouvertures (126) qui relie l'intérieur et l'extérieur du manchon (121) est fermée, l'autre est ouverte, et le piston libre (122) se déplace de la première extrémité à l'autre extrémité du manchon (121), amenant la surface d'ouverture de l'autre de la paire d'ouvertures (126) à diminuer.

ブレーキバルブ装置(100)は、リリーフ弁(105)の設定圧を調整する調整機構(102)は、一対の主通路の圧力に応じてスリーブ(121)内を摺動する単一のフリーピストン(122)と、スリーブ(121)外からスリーブ(121)内への流れを許容し、逆の流れを禁止する一対のチェック弁(123)と、を有し、フリーピストン(122)がスリーブ(121)の一端に配置されると、スリーブ(121)の内外を連通する一対の開口部(126)の一方が閉塞し他方が開口し、フリーピストン(122)がスリーブ(121)の一端から他端に向かって移動することにより、一対の開口部(126)の他方の開口面積が小さくなるように構成される。
