Abstract

Se proporciona un sistema de frenado por liberación de compresión que incluye un ensamble de balancín de escape de movimiento perdido, un pistón de accionamiento y un dispositivo de restablecimiento. El pistón de accionamiento incluye un cuerpo de pistón de accionamiento que se recibe en forma deslizante por el brazo de balancín para definir una cavidad de pistón en el brazo de balancín y que puede moverse entre las posiciones retraída y extendida del pistón. El pistón de accionamiento se configura para asociarse en forma operativa con la válvula de escape a fin de permitir el desasiento de la válvula de escape a partir del estado asentado. Una válvula de retención del pistón de accionamiento se configura para moverse entre las posiciones abierta y cerrada a fin de permitir el flujo de fluido hidráulico a través de un orificio de comunicación del pistón de accionamiento hacia la cavidad de pistón. El dispositivo de restablecimiento incluye una válvula de retención de restablecimiento y un muelle de control de la presión de restablecimiento para aplicar una fuerza de desviación a la válvula de retención de restablecimiento para empujar la válvula de retención de restablecimiento hacia una posición abierta.
