Abstract

Grupo cilindro-pistón bloqueable, que comprende un cilindro que está subdividido por un pistón en un vástago del pistón, en dos recintos de trabajo, presentando entre los dos recintos de trabajo una unión fluida que puede bloquearse mediante un dispositivo de válvulas, presentando el dispositivo de válvulas al menos dos válvulas individuales dispuestas en serie con sendos lados de entrada y salida de válvula, que se abren sucesivamente, estando dispuesto en el paso de la corriente entre las válvulas individuales un dispositivo estrangulador que presenta una reducción de presión entre el lado de salida de la primera válvula individual y el lado de entrada de la válvula siguiente, disminuyendo en su efecto el dispositivo estrangulador con el grado creciente de apertura de la primera válvula individual, y aumentando en la misma medida la aplicación de presión de la siguiente válvula individual en el lado de entrada de válvula.
