Abstract
La presente invencion se refiere a una válvula de derivacion o de tres vías que tiene una barra de control con una cámara piloto en cada uno de sus extremos. Para cada cámara piloto, existe un primer pasadizo conectado a la línea de presion y que comunica con la cámara piloto. Un segundo pasadizo se puede conectar a la vía de retorno. Una válvula de seguridad tiene un elemento de válvula desviado o inclinado para cerrar un orificio para interrumpir o cerrar la comunicacion entre la cámara piloto y el segundo pasadizo. El elemento de válvula tiene una posicion abierta en la cual la cámara piloto está conectada a la vía de retorno por medio del segundo pasadizo, para permitir el desplazamiento de la varilla de control. En una primera modalidad, la cámara piloto está continuamente en comunicacion con la presion a través del primer pasadizo, y el elemento de la válvula es abierto por esta presion en respuesta a la conexion del segundo pasadizo a la vía de retorno. En otra modalidad, el segundo pasadizo está en comunicacion continua con la vía de retorno, y el elemento de la válvula es movido mecánicamente hacia su posicion abierta por un operador o parte activa en respuesta a la presion que actua sobre la parte activa. Una válvula de control direccional de cuatro vías controla los conductos de derivacion que conducen desde la válvula de derivacion o de tres vías hasta los motores de accionamiento.
