Abstract
Válvula de protección (1) de múltiples circuitos para instalaciones de suministro de aire comprimido para vehículos de motor, con al menos dos válvulas de rebose (3) asignadas a un circuito correspondiente, cada una de las cuales presenta un elemento de válvula (4) que se apoya sobre un resorte (5), el cual forma junto con un asiento de válvula una válvula de paso (8, 9) para el aire comprimido hacia un consumidor de aire asignado al circuito, y con una unidad de control (38) asignada al circuito correspondiente para la apertura controlada de la válvula de paso (8, 9), que presenta una unidad de accionamiento (27), presentando la unidad de accionamiento (27) un pistón (28) y un empujador (30), caracterizada porque el elemento de válvula (4) de cada válvula de rebose (3) está conformado como pistón diferencial (10) con guarnición del émbolo (12), porque la superficie activa solicitada por el aire comprimido suministrado se reduce a una superficie activa parcial (14) a través de la guarnicióndel émbolo (12) por el lado del elemento de válvula (4) opuesto al resorte (5), y porque la fuerza del resorte (5) se dimensiona en correspondencia con la presión de apertura deseada de la válvula de rebose (3) sobre esta superficie activa parcial (14) reducida.
