Definitions

• the present invention relates to a tap for beer kegs according to the preamble of claim 1, which is suitable for both kegs and standard beer kegs.
• the bunghole is closed by a spring-loaded plug, in standard drums the plug is ejected into the inside of the barrel when tapped and sinks to the bottom.
• the tap can be fixed in the bung hole using a pinch seal, after which the tap's beer channel is e.g. driven by hammer blows against the plug and the plug pushed out (DE 33 06 204 A1).
• the present invention has therefore set itself the task of creating a tap in which the locking means are only exposed to a very low load, yet a safe locking function should be ensured, so that the life of the tap is significantly increased.
• the invention makes here for the means for fixing the valve housing relative to the sleeve and sleeve of the known as a ballpoint pen mechanism kinematic principle (see, for example, DE-GM 17 07 436 or DE-AS 12 59 735, FIGS. 6 and 7) use, the transfer of which to the remote area of the faucets to this end was previously unknown and also not suggested.
• the beer channel with the pinch seal surrounding it is inserted into the bung hole, with the tap housing in the position removed from the sleeve.
• the sleeve is turned and the rubber ring of the press seal is widened until the tap is fixed in the bung.
• a force is then applied to the valve body in the axial direction, e.g. exerted by a hammer blow, the tap housing and beer channel moving against the force of the coil spring in the direction of the stopper and driving it into the interior of the barrel.
• the beer channel moves relative to the sleeve fixed to the barrel and the toothed ring comes into the area of the webs of the second sleeve part, so that as a result of the opposite inclination, the toothed ring is rotated by a web width (the narrower bars of the second sleeve part).
• the beer channel in the sleeve moves back slightly and the ring teeth lie with their base against the contact sections of the first sleeve part.
• the beer channel or the tap housing again against the force of the coil spring, needs to be moved in the direction away from the keg.
• inclined surfaces of the webs of the second sleeve part act on the inclined surfaces of the ring teeth, turning the tooth so that ultimately the ring teeth are guided into the spaces between the webs of the first sleeve part, the coil spring being relaxed and the valve housing thereby in the barrel and away from the sleeve.
• the pinch seal When dismantling the tap, it is otherwise immaterial in which position the pinch seal is opened. It is only necessary to ensure that the sleeve is in the latter position before the tap is driven in, otherwise the pinch seal cannot be fixed.
• the cock housing At the bottom of the webs of the first sleeve part is advantageously an inward, the cock housing encompassing collar formed, which serves as a system for the ring, so that when the coil spring is relaxed, the position of the sleeve of the ring with its closed part lies against this collar and the ring teeth are thus relieved.
• the keys on the beer channel are followed by feather keys that engage in corresponding grooves in a coupling.
• the coupling has an external thread onto which the second sleeve part is screwed.
• the sleeve is also connected (screwed), which carries the pinch seal in a known manner.
• This consists of a tubular spacer (or sleeve) pushed onto the sleeve, a rubber ring being inserted between an end flange of the sleeve and the spacer (or sleeve) so that when the sleeve is rotated, the spacer squeezes or relaxes the seal .
• the beer line, as well as all parts of the tap housing that come into contact with the beer, are advantageously made of plastic, the tap housing itself of metal.
• arms extending into the tap housing before the stop can be integrally formed on the beer channel, which are equipped with locking elements, and which at the same time hold the beer channel on the tap housing.
• a further significant improvement in the functionality of the tap is achieved by a special shape of the spacer. This is conically shaped on the outside, so that when the tap is inserted, the beer channel lies against the stopper of the keg and the cone clamps with the outer edge of the bunghole.
• the tap is completely wobble-free by the further area of the spacer or the bush on the bung hole, the greatest possible distance being reached between the holding areas, so that relatively large forces can be included.
• the spacer can fall off conically from the center towards both ends, since this facilitates faultless installation. With conventional dimensions, about 1 ° can be used as the cone angle.
• Figure 1 shows the structure of the tap with locking mechanism in a spatial representation
• FIG. 2 the determination of the tap on the bung hole of a barrel; Beer channel in the withdrawn position shown in broken lines in FIG. 3;
• Figure 3 shows the function of the locking mechanism as a schematic diagram; in full lines with the beer channel pushed forward to open the barrel stopper, indicated by dashed lines, the position according to FIG. 2 with the beer channel withdrawn.
• FIG. 1 shows in the exploded view the metal tap housing 26 into which the beer channel 1 can be inserted.
• the beer channel 1 has arms 28 which engage in the corresponding recesses in the interior of the tap housing 26 and secure it against rotation.
• the beer channel 1 also has a bearing 29 for a ring 4, which has ring teeth 5 with inclined surfaces 6. Behind this is a stop 3 for the ring 4, the edge of the valve housing 26 represents the opposite stop 2 for the ring 4.
• the stop 3 is followed by feather keys 24, which in turn lie in grooves 23 of a coupling 19 and the latter against rotation to back up.
• the beer channel 1 and the connecting piece 31 are encompassed by a displaceable sleeve 7 which is screwed to the coupling 19 via its external thread (FIG. 2).
• the sleeve 7 consists of two sleeve parts 8 and 9, which have on their inner circumferential surfaces 10, 11 webs 12, 13, which at their ends have the ring 4 facing inclined surfaces 6 ', 6 ", the axial displacement of the tap housing 26 with the beer channel 1 the ring 4 opposite the sleeve 7 Twist gradually over the ring teeth 5 thereof, the ring teeth 5 having a base 15 facing the first sleeve part 8 (webs 12), which can be placed against systems 14 of the webs 12.
• a collar 18 is molded onto the first sleeve part 8, which surrounds its connector 31 and which at the same time serves as a contact surface for the ring 4 in its position with the coil spring 17 relaxed (see FIG. 2).
• FIG. 2 shows the second sleeve part 9 with the webs 13 and their inclined surfaces 6 ".
• the beer channel 1 is surrounded by the helical spring 17, which rests against the feather keys 24 formed on the beer channel 1 and against a recess 32 of the sleeve 20, which over a Internal thread of the coupling 19 is screwed to the coupling 19.
• the coupling 19 also has an external thread which meshes with an internal thread of the second sleeve part 9.
• the pinch seal is formed by an end flange 33 with an attached rubber ring 22 encompassing the sleeve 20 and a bushing 27 acting as a spacer, which is displaced relative to the sleeve 20 by the sleeve 7 during rotation,
• the conical design of the bushing 27 is of importance for secure clamping in the bunghole 36, so that its thickening central region clamps on the bunghole edge 34 of the barrel 35 and reliably secures the tap against wobbling and aligns the beer channel 1 coaxially with the bunghole 36.
• FIG. 3 shows the function of the locking mechanism used according to the invention.
• the ring 4 which is axially fixed and rotatably connected to the tap housing 26 or the beer channel 1, has radially projecting ring teeth 5 with inclined surfaces 6 and base surfaces 15.
• the ring teeth come into the area of the sliding wedges 16 of the webs 12 when When the helical spring 17 is relaxed, the ring teeth 15 slide downward on these sliding wedges 16, as a result of which the ring 4 is rotated further, so that the ring teeth 5 are located in the intermediate regions 30 between the webs 12 of the first sleeve part. In this position (shown in broken lines in FIG. 3) the beer channel 1 withdrawn, corresponding to the position shown in Figure 2.
