Definitions

  • This invention relates to an installation making it possible to recover a working gas such as, for example, carbonic acid or nitrogen, used for the purpose of dispensing drinks, from one, but preferably several barrels.
  • a working gas such as, for example, carbonic acid or nitrogen
  • the object of the invention is to prescribe an installation which operates entirely automatically and which can be controlled from the place where the drink is dispensed.
  • the installation comprises, for each barrel, a first pipe for alternately supplying a gas to a barrel from which liquid is withdrawn and, when the latter no longer contains liquid but only gas, to suck this gas using a compressor and evacuate it to an expansion tank which can discharge the gas stored by supply lines to said drums, said supply pipes being connected to three-way electromagnetic valves beyond which the gas can flow to one of the drums considered or be sucked out of them by the aforementioned compressor.
  • the aforementioned three-way electromagnetic valves are connected to a common pipe which leads, via a bypass, to the aforementioned compressor, said compressor being, downstream thereof, connected by a pipe to at least one tank accumulation.
  • the invention also relates to the compressor of original design, operating without lubricant, which finds application in the installation according to the invention.
  • the installation shown schematically in Figure 1 is designed to recover a driving gas such as carbonic acid or nitrogen from drums 1, 2 and 3, when they no longer contain any drink and in order to lead gas to barrels when they are to dispense a drink.
  • a driving gas such as carbonic acid or nitrogen
  • the flow lines, partially visible, have the reference 4.
  • the pipes 5 ⁇ , 6 ⁇ and 7 ⁇ for the engine gas are derived from a main pipe 8.
  • a main pipe 8 On this main pipe 8 are mounted, downstream of the expansion tank 9, an assembly 10-11 constituted by a discharge valve of liquid, an activated carbon filter and a bacteriological filter.
  • the expansion tank 9 is, conventionally, fitted with a safety valve 12 and, on the line 13 which leads to the compressor 14, a non-return valve 15 is installed.
  • the drums 1, 2 and 3 are also put in communication with the compressor 14 using a pipe 16.
  • Each of the pipes 5, 6 and 7 can indeed be put in communication with this pipe 16 by the intervention of the three-way electromagnetic valves 17, 18 and 19.
  • a first branch 20, connects line 16 to the compressor 14.
  • a second branch, 21, leads to a line 22 and extends between the coil 23, connected in line 13 and a gas cylinder 24. It immediately appears that the supply lines 5 ⁇ , 6 ⁇ and 7 ⁇ transform, beyond the three-way valves 17, 18 and 19 what is called the first lines 5, 6 and 7 which act, both in order to recover the engine gas as well as for bringing it to new barrels from which the drink will have to be taken.
  • recovery tanks 25 On the pipe 22 are mounted recovery tanks 25. On the same pipe 22 are mounted one after the other the others: a valve 26, disposed between the compressor 14 and the bypass 21; a pressure detector 27; a safety valve 28 and, immediately downstream from the gas cylinder 24, a pressure regulator 29.
  • a non-return valve 32 is mounted on the bypass 21 .
  • the reference 34 represents a pressure detector with which the expansion tank is equipped 9.
  • the mini-computer of the installation is represented by the general reference 35 and the control panel with the reference 36.
  • the compressor 14 forms an essential element of the installation and is designed to require no lubricant, which makes its structure particularly original.
  • the compressor consists of a casing 37 having a cylindrical cavity for a double piston 38 which is driven back and forth within the cylindrical cavity of the casing. This back-and-forth movement is caused by a drive wheel 40 mounted eccentrically relative to the drive axis 39. This wheel is freely mounted on the axis 41 fixed on the disc 42 mounted on the drive axis 39.
  • the disc 42 is housed in a cylindrical cavity 43 which is in communication with the cylindrical space in which the piston 38 moves. The seal between said space and the outside is ensured by virtue of the presence of the sealing washer 44 which is supported by its folded rim on the drive shaft 39. In the space 43 opens the suction pipe 45 for the engine gas. Good cooling of the elements which constitute the piston 38 is thus ensured.
  • the outlet valves and the outlet pipes are provided at the two ends 46 and 47 arranged opposite one another in the compressor casing.
  • the inlet valves are designated by 48 and 49, the outlet valves bear the references 50 and 51.
  • the outlet pipes bear the references 52 and 52 ⁇ .
  • passages 53 and 53 ⁇ In the wall of the housing 37 are provided passages 53 and 53 ⁇ to allow the circulation of the engine gas in the direction of the valves entry 48 and 49.
  • the piston 38 which consists of two identical piston elements 54 equipped with segments 55.
  • the piston elements 54 which are made of a light metal such as l aluminum or an aluminum alloy, there is a piece forming a spacer 56 in the geometric axis of the piston elements 54 as well as a cylindrical piece forming a spacer 56 is a threaded rod which provides the connection between the piston elements 54 and the spacer 56 also blocking the metal discs 57.
  • These discs are provided to guarantee these piston elements against wear.
  • the space between the discs 57 and the drive wheel 40 must be chosen so that the rotation which is caused by the friction between the drive wheel 40 and the discs 57 can continue without difficulty but also without shock, in both directions.
  • each of the piston elements 54 consists of two parts.
  • the actual piston portion 54 made of a synthetic material such as that which is known in the trade under the name of "Rulon” and the elements 54 ⁇ made of light metal.
  • the compressor according to the invention is, as follows from the description which has just been given, gas-tight, requires no lubrication, which is an essential element. That no lubrication is necessary, results from the correct choice of the inlet of the suction line 45 for the engine gas which immediately cools the parts which otherwise would heat up and, on the other hand, as desired materials of which the elements of the piston are made.
  • Good sealing of the segments 55 is ensured by providing outside of the piston 38, at the height of each segment 55 a spiral spring 58 which is housed in a circular groove 59 of the piston 38. This spiral spring 58 supports the segments 55 towards the exterior and thus ensures the necessary tightness between the segments and the internal wall of the cylindrical space in which the piston 38 moves.
  • the operation of the installation is as follows:
  • a keg no longer contains any drink for example keg 2. He then presses the corresponding key on the table, for example the key D. By pressing this key the corresponding three-way valve 18 is placed in the position in which the compressor 14 sucks the engine gas through the line 18 and the bypass 21. At this time the line 6 ⁇ is closed. The ensuing lack of pressure in a barrel is signaled by the pressure detector 30. In this phase, the valves 26 and 33 are closed and the compressor 14 is stopped. A new keg containing the drink to be dispensed is then installed. The user must then press the R "reset" button. This means that the barrel receives its pressure directly from the accumulation tank 9, the valves 26 and 33 are closed.
  • the valve 26 When, during the emptying of a barrel, the pressure in the expansion tank has reached the predetermined pressure, i.e. for example a pressure of 6 kg, the valve 26 opens so that the excess gas is pumped out of the barrel to the accumulation tanks 25. When the detector 30 detects zero pressure, the compressor 14 is stopped and the valve 26 is closed. When, conversely, during the flow of drink from barrels 1, 2 or 3, the pressure in the expansion tank falls below a predetermined value, for example under a value of 4 kg, the valve 26 remains closed, the valve 23 opens while the compressor 14 rotates which makes it possible to bring the necessary quantity of engine gas from the accumulation tanks to the expansion tank.
  • a predetermined value for example under a value of 4 kg
