Abstract
La presente invencion reivindica, a titulo de nuevo producto industrial, un montaje de sello de vastago de valvula que incluye un reten con un cuerpo de sello elastomerico unido al interior del reten. El cuerpo de sello incluye miembros de sellamiento anulares primero y segundo que acoplan con el vastago de valvula y una guia de valvula, respectivamente. El cuerpo de sello tambien incluye un tercer miembro de sellamiento anular que sobresale ligeramente por debajo de una superficie inferior de una porcion con pestana inferior del reten, adaptada para acoplar con una cabeza de cilindros. El maquinado escaso de la guia de valvula y/o la cabeza de cilindros, con frecuencia crea una trayectoria de fuga de aceite que fluye debajo del sello y a traves de aberturas entre la guia de valvula y la cabeza de cilindro. El tercer miembro de sellamiento anular sella la trayectoria de fuga. El cuerpo de sello elastomerico tambien incluye costillas axialmente dispuestas cerca del fondo del reten con areas espaciadoras de metal expuesta en forma de ventanas entre las costillas, lo cual baja los costos del montaje de sello por la cantidad reducida de material elastomerico requerida para su manufactura.
