Abstract

Pump for extracting liquid from a container, characterized in that it comprises a plunger body that is coupled by rocks to a basic part, which has fixing means to the basic one, which presents fixing means to the upper part of the container, while the basic part is provided with a recessed portion, centrally bored, where a valve positioned by a spring is arranged, which is accentuated by a cylindrical part, when it is coupled in a sealed manner in the recess, so that the air passing through the valve is directed by an inner conduit of the circular piece to an exit chamber delimited by the inner wall of a tubular projection, emerging from said piece, and a hexagonal socket coupled in said projection, leaving the air towards the interior of the container by holes made in the upper area of a tube that is threadedly attached to the projection of the circular piece, and that, in turn, the tube presents a pi elastic coupling to an opening in the lid of the container; and because due to the overpressure created by the air inside the container, the liquid rises through an inner tube coupled to the hexagonal cap and disposed inside the outer tube, where it sits at its free end, while upperly the inner tube is communicates with an inner conduit of the cylindrical part, through which the liquid passes and which is directed by a conduit, which forms part of the basic part, towards the outlet mouth, the liquid outlet being regulated by a manually operated lateral valve.
