Abstract

Las "válvulas de control" relativamente complejas y costosas, las cuales son usadas convencionalmente en ciertos frenos de liberacion de compresion del motor para propositos tales como llenado, aislamiento y ventilacion de las porciones de alta presion de los circuitos hidráulicos en el freno del motor, son eliminadas y se proporcionan medios más directos para realizar estas funciones. En los frenos que tienen un mecanismo para reajustar cada uno de los émbolos esclavos (62), la porcion de alta presion del circuito es llenada a través de una apertura que se abre selectivamente (64a) en el émbolo esclavo (62). En los frenos que tienen un mecanismo para ajustar automáticamente el juego del émbolo esclavo y para limitar ("sujetar") la carrera hacia adelante del émbolo esclavo, se proporciona el llenado del circuito de alta presion a través de una simple válvula de retencion. En los sistemas en los cuales el líquido hidráulico es desplazado temporalmente desde el circuito de alta presion, se proporciona un solo acumulador (240) para almacenar el líquido hidráulico para el rellenado rápido. Un solo acumulador (240) de este tipo puede reemplazar multiples válvulas de control.
