Abstract
Drain valve consisting essentially of a sleeve mounted in the lower opening of the tank, at the lower end of which is attached a tank with a lower opening provided with a stopper and a lateral exit duct in the form of a siphon inside of which sleeve is mounted sliding axially a closed tubular body with openings at its ends as a grid leaving the lower end located below the exit conduit of the siphon while the upper end is below the edge of the tank on which the valve is mounted and presents in its vicinity grooves that act as an overflow, finally disposing the tubular body of another series of intermediate grooves susceptible of being obstructed by the sleeve itself or protruding from it by displacement of the tubular body acting as a drain.
