Abstract

Dispositivo de émbolo para muelle neumático u otro aparato telescópico de cilindro y vástago buzo, estando este dispositivo de émbolo dispuesto para conducir al vástago buzo dentro del cilindro y subdividir este último en dos cámaras que se comunican entre sí mediante un canal dispuesto a través del émbolo, el cual comprende por una parte un cuerpo de émbolo montado de forma deslizante sobre el mencionado vástago buzo entre dos topes solidarios de éste y por otra parte un segmento de estanqueidad montado de forma flotante con relación el cuerpo del émbolo, pudiendo las dos piezas simplemente hacer tope libremente una contra la otra para desplazarse de común acuerdo, caracterizado porque uno al menos de los mencionados dos topes sirve, no solamente de órgano limitador de deslizamiento del émbolo, sino también de órgano obturador que tapa parcialmente la desembocadura del mencionado canal cuando el émbolo hace tope contra el, y porque el mencionado segmento de estanqueidad que acaba de fricciona contra la pared del cilindro está montado por fuera del cuerpo del émbolo y coopera con el tope limitador correspondiente para el ejercicio de la función de obturación parcial deseada.
