Disclosed is a pneumatic valve for a vehicle, including: a valve housing having a passage inside which air flows; a core fixed to a center of the passage; a plunger disposed to face at least one end of both ends of the core, and moving along the flow path; and a damper of an elastic material disposed at one end of the plunger facing one end of the core and contacting one end of the core by movement of the plunger. The damper has a protrusion protruding in an outer circumferential direction at an end portion contacting one end of the core. Further, a housing space is included where the protrusion is accommodated in a case where the protrusion is deformed due to a contact pressure between the protrusion of the core and the damper. As such, the present invention is able to reduce noises and vibrations generated when a plunger and a core contact each other and to eliminate a phenomenon that a spring is stuck while protruding outwardly between a core and a space where the plunger moves in such a manner that the spring of a core portion is compressed, thus preventing noises by an operation from being generated and performance thereof from being degraded.

    내부에 공기가 흐르는 유로가 형성된 밸브하우징; 상기 유로의 중앙에 고정된 코어; 상기 코어의 양단 중 적어도 일단에 대면하도록 배치되며, 상기 유로를 따라 이동하는 플런저; 및 상기 코어의 일단과 대면하는 상기 플런저의 일단에 배치되며, 상기 플런저의 이동에 의해 상기 코어의 일단과 접촉하는 탄성 재질의 댐퍼를 포함하며, 상기 댐퍼는 상기 코어의 일단과 접촉하는 단부에 외주 방향으로 돌출된 돌출부를 가지며, 상기 코어의 돌출부와 상기 댐퍼 사이에는 접촉 압력에 의해 상기 돌출부가 변형되는 경우 상기 돌출부가 수납되는 수납 공간을 갖는 차량용 공압 밸브가 개시된다.
