Abstract

Una válvula sujetadora para limitar la carrera de un émbolo hidráulico actuador (20) que opera una válvula de escape en un freno de liberacion de compresion del motor que tiene un tapon (60), el cual sigue el émbolo actuador hacia abajo hasta que el movimiento de dicho tapon es detenido por un anillo de retencion (80) en una perforacion (72) en la cual el tapon actua en reciprocidad. El tapon es detenido de este modo, se descubre una apertura (24) en el émbolo esclavo (20), permitiendo de este modo que el líquido hidráulico presurizado se escape del cilindro (40) del émbolo actuador y previniendo el movimiento adicional hacia abajo del émbolo actuador. El aparato de la válvula sujetadora está construido para facilitar el ensamble del tapon y el anillo de retencion en la perforacion, así como para producir una retencion segura y libre de fallas de estos componentes en la perforacion. Las partes de la válvula sujetadora son amplificadas y preferentemente también se reduce la cantidad de componentes. Comparada con las válvulas sujetadoras del arte previo.
