Abstract
A blower tap, characterized by being constituted by a metallic body of cast iron whose inner conduit, experiences an angular difference corresponding to the central core occupied by the valve, composed this, by a threadable bushing in whose internal cylindrical space slides a vertical piston which it is maintained at the appropriate height and oscillation, by means of a coil spring spring, which working by extension occupies the internal space or sheath of said plunger, after supporting its lower end in a hollow seat of the base of the valve cavity.
