Abstract

Lo que revela es una válvula de control de altura para controlar la alturade un resorte neumático, en la cual la altura controlada del resorteneumático puede ajustarse fácilmente. La válvula de control de alturacomprende un orificio interior que se encuentra en comunicación con unpuerto de entrada, un puerto de descarga y un puerto de resorte neumático.Un pistón hueco es móvil dentro del orificio de la válvula en respuesta alos cambios en la altura de un resorte neumático. La pieza de sellado sedesvía hacia un asiento de válvula para sellar el puerto de entrada, y unextremo abierto del pistón hacia la pieza de sellado desengancha la piezade sellado desde el asiento de la válvula, colocando el puerto de resorteen comunicación con el puerto de entrada. El movimiento axial del pistónlejos de la válvula del disco coloca al puerto de resorte en comunicacióncon el puerto de descarga a través del interior del pistón. La alturacontrolada del resorte neumático se ajusta, ajustando la posición axialdel asiento dentro del orificio de la válvula.
