Abstract

Perfeccionamientos en impulsores accionados por fluido a presión caracterizados por comprender un vástago de actuación axialmente móvil en sentidos opuestos y prolongado a través de una abertura ensanchada de una de las paredes del impulsor para permitir el movimiento lateral del vástago durante su desplazamiento axial y además por acoplar un grupo o dispositivo de empaquetadura o guarnición que rodea al vástago y comprende un disco anular de obturación o cierre con una de sus caras ajustada en la cara exterior de la pared citada alrededor de la abertura mencionada; un elemento en forma de copa o platillo que se ajusta en la cara opuesta del disco indicado y está dotado de una pestaña anular que se ajusta con la parte periférica de dicho disco; un manguito montado a deslizamiento en el vástago y dotado de un borde que se ajusta en dicho elemento; el manguito mencionado se prolonga libremente a través de la abertura indicada al interior del impulsor; y medios elásticos entre la cara interior de dicha pared y el manguito citado para empujar el disco mencionado en ajuste de cierre con la cara exterior de dicha pared por la cooperación con el borde de dicho manguito y el elemento mencionado.
