Abstract

Pneumatic device coupled to doll carrying elements, for driving them, characterized in that the part of the carrier element that performs the function of handlebar for driving thereof, is provided with an elastic fluid reservoir superimposed on it, in the this position is convenient for its actuation by pressure simultaneously to said conduction, whose reservoir is equipped with a valve constituted by a membrane located inside a box provided with an orifice for the entrance of the exterior fluid, on whose internal face some prominences that allow together with the coupling of the membrane to said inner part when the fluid tends to circulate in the direction of exit to the outside, the hermetic closing of said orifice, preventing the exit thereof; existing on the inner side of the box opposite the inside, other prominences that hinder the passage of the membrane to prevent closing the hole that also exists on said opposite face when the fluid tends to circulate in the direction of entry, from the outside and exit through the last indicated orifice, with what is achieved that the valve allows the entry of the fluid coming from the outside and its circulation in that direction, but not its exit to the outside in the opposite.
