Abstract

En los frenos del motor del tipo en el cual un émbolo maestro (82) es alternado por una parte de un motor de combustion interna asociado para presurizar hidráulicamente el líquido hidráulico en un pleno (60), después de lo cual, una válvula de gatillo (100) es abierta para aplicar esa presion hidráulica a un émbolo esclavo (120), el cual abre una válvula de escape (132) en el motor para producir un evento de liberacion de compresion, es usada una válvula de gatillo (100) controlada electronicamente, en lugar de la válvula de gatillo convencional operada mecánicamente. La válvula de gatillo controlada electronicamente (100) puede ser mucho más simple y barata que la válvula de gatillo mecánica a la que reemplaza y puede también ser controladas fácilmente para variar automáticamente la programacion de los eventos de liberacion de compresion, si así se desea.
