Abstract

La invención se refiere a un cilindro (1) diferencial para un accionamiento hidromecánico para actuar un interruptor eléctrico, en particular un interruptor de alto voltaje, que comprende una primera región (3) de presión para ser cargada con una presión de operación; una segunda región (4) de presión; y un pistón (2) que se puede mover en un intervalo de movimiento y que se puede mover en función de una diferencia de presión entre la primera y la segunda región (3, 4) de presión; caracterizado porque se proporciona un dispositivo amortiguador que durante un movimiento del pistón (2) en la dirección de la segunda región (4) de presión en una sección (D) del intervalo de movimiento proporciona amortiguación adicional contra el movimiento del pistón (2), siendo que la amortiguación adicional es ajustable.
