Definitions

  • a part of the column body of the tappet 30 is arranged in a spring shape, and the rigidity of the spring-like column body is smaller than the rigidity of the return spring 50.
  • a part of the column of the tappet 30 is arranged in a spring shape, that is, the upper column of the tappet 30 can be arranged in a spring shape, and the lower column body can be arranged in a solid shape; or the lower column of the tappet 30 can be arranged. It is spring-like, and the upper column body is provided in a solid shape; the column bodies on the upper and lower sides of the tappet 30 may be provided in a solid shape, and the intermediate portion between the upper and lower sides may be arranged in a spring shape.

Abstract

L'invention porte sur un mécanisme de distribution de moteur avec soupape à air à levage réglable, comprenant une came (11) disposée sur un arbre à cames (10), un culbuteur en forme de doigt (20) disposé en dessous de la came (11) qui est en contact contre le palier du culbuteur (20) et peut tourner avec celui-ci, un poussoir de soupape réglable verticalement (30) disposé en dessous d'une extrémité du culbuteur (20) et une soupape à air (40) disposée en dessous de l'autre extrémité. Le culbuteur (20) peut tourner autour de son interface avec le poussoir de soupape (30), et un ressort de rappel (50) est disposé sur la tige de la soupape à air (40). La position du poussoir de soupape (30) peut être réglée verticalement de façon à régler le levage de la soupape à air. Le mécanisme de distribution est de structure simple, et fonctionne de manière stable et fiable.
