Definitions

• the invention relates to a dispensing device for kegs according to the preamble of claim 1.
• a pump cylinder and a distributor base are made in one piece from plastic, the pump cylinder can essentially be screwed coaxially onto the liquid nozzle, and the liquid line runs into a Cross bore opening laterally from the distributor base.
• the keg fitting assigned to this dispensing device is, however, specially designed for the connection of the distributor base of the pump cylinder and deviates from the generally customary keg fitting, as they are based on the generic dispensing device, insofar as they do not separate each of them structurally and individually from the liquid outlet nozzle Has accessible compressed gas inlet connection.
• the last-mentioned dispensing device can therefore not be used together with the generally customary keg fittings.
• the compressed air pump is coaxial with the keg fitting, but it is not attached to a dispensing head, but directly on the keg fitting, and has its own for this purpose Opening rod for the keg fitting.
• the pump thus only fits a special keg fitting and is unusable for other keg fittings, of which about 30 different types are on the market.
• the dispensing tap is located relatively high up at a considerable distance from the keg, so that, in turn, tilting moments arise via the large lever arm thus formed.
• the relatively long liquid line connecting the tap to the keg is also difficult to clean.
• the object is achieved by the characterizing features of claim 1.
• the liquid line formed directly in the distributor base is relatively short, so that no cleaning problems arise. It can also be connected directly to a tap at the height of the distributor base below, so that the stability of the arrangement is largely ensured even when tapping.
• FIG. 1 shows a partial sectional view of a dispensing device for kegs
• FIG. 1 schematically shows the tap in
• Figure 3 is a bottom view of a piston rod guide.
• FIG. 1 of the drawing shows a conventional tap head 1 for a keg.
• the tap head 1 is detachably connected in a manner known per se with its underside, for example by screwing or bayonet fitting, to a keg fitting (not shown, known per se) fixedly arranged on the keg.
• the tap head 1 has one liquid outlet connecting piece 2 going upwards and a compressed gas inlet connecting piece 3 going out laterally at an angle.
• a compressed air pump 7 is coaxially screwed onto the liquid outlet nozzle 2 of the dispensing head 1, which comprises a piston 9 with a sealing ring 11 which can be moved back and forth into a pump cylinder 8.
• the piston 9 is connected to a pump handle 13 via a piston rod 12, which is designed in the form of a cross rib.
• the piston 9 can be moved back and forth in the pump cylinder 8, so that air is sucked in in a conventional manner when the piston goes up and the suctioned in when the piston goes down and compressed and released as compressed air .
• the pump cylinder 8 runs in one piece on its underside into a distributor base 14 which has an internal thread on its lower end for screwing to the liquid outlet connection 2 of the dispensing head 1.
• the seal between the connection piece 2 and the connection piece 14 takes place via a sealing ring 15.
• the pump 7 is thus connected coaxially to the dispensing head 1 and the keg carrying this dispensing head.
• a liquid line 16 is formed which communicates directly with the liquid outlet connection 2.
• the line 16 merges into a transverse bore 17 opening laterally from the distributor base 14, into which a tap 18 - see FIG. Figure 2 - can be screwed in.
• the tap 18 is designed as a pinch tap and contains a hose which can be squeezed or opened with the aid of a rotary slide 19.
• An outlet pipe 21 of the tap 18 with outlet opening 22 preferably extends substantially beyond the outer circumference of the (not shown) keg so that it can be conveniently tapped.
• a compressed air line 23 is formed in the distributor base 14 separately from the liquid line 16 and the transverse bore 17, which on the one hand opens into the lower end of the pump cylinder 8 and on the other hand on the side of the distributor base 14.
• This line 23 is connected via a hose 24, as shown by dash-dotted lines, to the compressed gas inlet connection 3 of the tap 1, so that the compressed air generated by the pump 7 can be introduced into the keg in a conventional manner in order to dispense the liquid to be drawn off, e.g. To drive out beer.
• a piston rod guide 25 is inserted into the upper end of the pump cylinder 8 and has a cross slot 26 for guiding the cross-rib-shaped piston rod 12, which in turn is integral with> at its lower end.
• TI piston 9 is connected.
• the piston rod guide 25 consists of two essentially mirror symmetrical halves 27 and 28, which are applied from the outside to the cross-rib-shaped piston rod 12, together with this rod can be inserted into the pump cylinder 8 and locked there.
• a corresponding spring 29 is integrally formed on both halves 27, 28 and can be snapped into a corresponding recess 30 on the pump cylinder 8 (FIG. 1).
• the piston rod guide 25 is also made of plastic.
• the piston rod guide 25 providing a sliding guide further forms, as can be seen from FIG. 1, an upper end stop 31 for the pump piston 9.
