Abstract:
1. A retractable tap for drawing pressurized liquid from a liquid container unit and for insertion into a container opening provided in a sidewall of the liquid container unit closer to a topside of said container unit than to a bottom part, the retractable tap comprising an outer sleeve comprising an outer end, an inner end, and a locking mechanism arranged in the vicinity of the outer end for effecting a seal-tight attachment in the container opening, wherein an axial direction of the outer sleeve, in a mounted state in the container opening, extends horizontally or substantially horizontally; a tube arranged seal-tightly and slidably in an inner passage of the outer sleeve; wherein the tube comprises a tube wall and a grip connected to the tube wall, wherein the grip is positioned externally to the container unit when the outer sleeve is in the mounted state and wherein the tube wall has a discharge opening for liquid adjacent to the grip; wherein the tube has an inwardly positioned end face that is remote from the grip and is provided with intake openings and with a pin projecting from the end face; means provided on the outer sleeve and on the tube that limit a sliding action of the tube between a first position that is an open tube position in which the discharge opening projects from the outer sleeve and a second position that is a closed tube position in which the tube is inserted into the outer sleeve to such an extent that the outer sleeve completely covers the discharge opening; a valve device closing off the discharge opening of the tube seal-tightly against penetration of liquid in a closed position of the valve device; an actuating device acting on the valve device and arranged at the grip, wherein the actuating device opens the valve device against a force that forces the valve device into the closed position; a protective cover comprising a first portion and a second portion, wherein the first portion is tubular and is pushed onto the inner end of the outer sleeve to such an extent that the first portion seal-tightly covers the outer sleeve, wherein the second portion adjoins the first portion in the axial direction of the outer sleeve and has a tubular recess seal-tightly surrounding the pin in the second position of the tube in which second position the tube is completely inserted into the outer sleeve and wherein the pin is moved out of the tubular recess in the first position of the tube; wherein the outer sleeve has a circumferential wall having no opening in areas of the circumferential wall that are not covered by the protective cover so that no fluid communication through the circumferential wall is possible between the container interior and an interior of the outer sleeve in the open tube position and in the closed tube position of the tube; wherein the protective cover has a closed-off end face remote from the first portion and has a lateral opening provided with coupling means for seal-tightly coupling a pipe or a hose thereto; wherein the lateral opening, in a second state of the tube in which second state the tube is pushed out of the outer sleeve, is in fluid connection with an interior of the tube.
