Abstract

Perfected hydrant of the type of constituted through an extensioned body, intended to be partially buried in their upper zone, side outlet bushes are established, assisted by the corresponding protective covers, and in which the lower extreme is established a body of connection to the network of water supply, at the same time that the connection body incorporates a closing housing superior, on which the hitrant shutter actuates, actuated from the higher limb thereof, through its transmission axis, which receives the movement from a head emerging through the upper cover of the body, and allowing the application of an appropriate tool, essentially characterized because the above axis of transmission incorporates in its extreme superior area and in replacement of the classic thread a helical channel of great step and of section in a half rod, while the head of foreign drive is associated with a cap mounted with freedom d i giroen the body and provided in its side wall of a plurality of holes or accommodations for respective balls, with the particularity that these accommodations are troncoconic so that the balls have direct access to them from the outside of the cap and penetran substantially in the sine of the same, to be coupled in the helical channel of the upper limb of the axis, all of it so that with an angular turn of the driving head, of small amplitude, a considerable axial displacement of the axis of transmission is given to the shutter, and all this with a minimum effort derived from the ball set constituting the transforming elements of the rotating cap movement in an axial movement of the axis.
