New model of key for the passage of fluids, characterized in that it consists essentially of a turning rod that acts on an eccentric that is in contact with a central part, which acts as a closing of the passage of the fluid by the action of a spring that maintains said step, which only opens when the eccentric in its rotation displaces the said central part, overcoming the pressure of the spring and allowing the passage of the fluid.
