Abstract

Tap for hot and cold water adjustable and automatic closing, which is essentially characterized because it is constituted from a pedal, which has laterally two lugs that are related to a shaft of faceted ends, in one of which is fixed a piece that includes a toothed sector, which engages in a pinion carried by an axis that is inside an airtight but practicable box, supporting said axis, two eccentrics set at a certain angle, which act alternately on respective levers layered, whose respective ends push balls or spheres seated on elastic O-rings, as shutters of hot and cold water pipes, in a housing that also has filter grids, all arranged so that when stepping the pedal, act one of the cams allowing a certain amount of cold water to pass until reaching a maximum flow, at which time the ec the center that motivates the hot water outlet, so that the more it opens, the cold water inlet will decrease, all this depending on the eccentric killings, and that is given by the greater or lesser amplitude of the angle than when stepping the pedal forms the same with the horizontal, having provided a single outlet of water mixture in the sink in question, and that through the action of a spring spring the pedal, to stop stepping on it, recover its position rest, thereby cutting off the supply of liquid flow.
