Abstract

Válvula de expansión (1) que tiene un elemento de válvula (6), elemento que coopera con un asiento de válvula (4) dispuesto entre una primera lumbrera (2) y una segunda lumbrera (3) en un alojamiento (5), y es movible mediante un dispositivo de accionamiento (8) en un sentido y mediante un dispositivo de restitución (10) en el sentido opuesto a lo largo del mismo eje geométrico (7) con relación al asiento de válvula (4). El elemento de válvula (6) está conectado a una primera disposición de superficies de presión (20, 21) que comprende primeras superficies de presión de esencialmente igual tamaño que actúan en sentidos opuestos, sobre las que actúa la presión en la primera lumbrera (2) cuando está cerrada la válvula, y a una segunda disposición de superficies de presión (22, 23), que comprende segundas superficies de presión esencialmente de igual tamaño, que actúan en sentidos opuestos, sobre las que actúa la presión en la segunda lumbrera (3) cuando la válvula está cerrada.
