Title (EN) LEVELING VALVE
(FR) SOUPAPE DE MISE À NIVEAU
(JA) レベリングバルブ
Abstract:
(EN) A leveling valve (100) according to the present invention comprises: a piston (20) that is accommodated in an accommodation hole (11a) formed in a housing (10) and moves inside the accommodation hole (11a) in accordance with the amount of relative displacement of a vehicle body (1) with respect to a dolly (2); and a rotation restricting portion (50) that is provided on the housing (10) and the piston (20) and restricts the piston (20) from rotating about a first central axis (O1) of the accommodation hole (11a) while guiding the piston (20) along a direction of the first central axis (O1).
(FR) La présente invention concerne une soupape de mise à niveau (100) comprenant : un piston (20) qui est logé dans un trou de réception (11a) formé dans un boîtier (10) et se déplace à l'intérieur du trou de réception (11a) en fonction de la quantité de déplacement relatif d'une carrosserie de véhicule (1) par rapport à un socle roulant (2) ; et une partie de limitation de rotation (50) qui est disposée sur le boîtier (10) et le piston (20) et limite la rotation du piston (20) autour d'un premier axe central (O1) du trou de réception (11a) tout en guidant le piston (20) le long d'une direction du premier axe central (O1).
(JA) レベリングバルブ(100)は、ハウジング(10)に形成された収容孔(11a)内に収容され、台車(2)に対する車体(1)の相対変位量に応じて収容孔(11a)内を移動するピストン(20)と、ハウジング(10)及びピストン(20)に設けられ、収容孔(11a)の第1中心軸(O1)方向に沿ってピストン(20)を案内しつつ、ピストン(20)が第1中心軸(O1)を中心に回転することを規制する回転規制部(50)と、を備える。
