Abstract

En un primer aspecto la presente invención consiste en un dispositivo que incluye una válvula de escape, que opera sobre un fluido de trabajo presurizado, que comprende o incluye, una cámara de trabajo, definida al menos en parte por una pared lateral, cuya cámara de trabajo puede sostener una carga de trabajo hacia un primer extremo de esta, la cámara de trabajo para recibir el fluido de trabajo para actuar sobre una superficie posterior de la carga de trabajo para impulsar la carga de trabajo hacia un segundo extremo, opuesto al primero, de la cámara de trabajo, una cámara de retorno para recibir el fluido bajo presión de una superficie frontal de la carga de trabajo, la presión desarrollada al menos en parte por el movimiento de la carga de trabajo hacia el segundo extremo, una válvula de escape conectada fluidamente a la cámara de retorno, la válvula de escape normalmente sesgada cerrada impidiendo que el fluido de trabajo salga de la cámara de trabajo, pero al recibir y actuar el fluido bajo presión de la cámara de retorno, se abrirá para permitir que el fluido de trabajo salga de la cámara de trabajo a un lugar de menor presión, saliendo el fluido de trabajo por la pared lateral de la cámara de trabajo a través de la válvula de escape, en el que se proporciona un dispositivo que eliminará o reducirá la presión que se acumula en la superficie trasera de la carga de trabajo cuando se mueve desde el segundo extremo hasta el primero.
