Definitions

  • the present invention relates to a device for the protected adjustment of the outflow of fluids in systems for dispensing drinks, comprising an outer end, accessible by the user to actuate a device for operating the adjustment.
  • drink distribution systems comprise different devices for adjusting the outflow of the drink or of the component fluids of the drink.
  • compensating organs for taps dispensing carbonated drinks are, for instance, known. They are substantially conical elements, positioned along a cone frustum shaped segment of the conduit for the outflow of the beer, upstream of the shutter for closing and opening the conduit, commanded by an external knob. In this way they allow to brake and adjust the flow of beer to make it more controllable, varying the outflow port by the simple axial displacement of the compensating organ, due to the action of said command appendage.
  • the command appendage has a parallel axis, eccentric relative to the axis of the end, so that the axial displacement of the compensating organ can take place simply by causing the element transmitting the adjustment (and the appendage therewith) to rotate about its axis, for a sufficient arc to allow the compensating organ to make a rotary-translatory displacement, where only the translation component is functionally essential.
  • known adjusting devices simply provide a small lever, integral with the outer end, rotating which the adjustment is performed.
  • the pressure is normally adjusted through a simple action by the operator on an external knob for actuating an adjustment screw engaged in the body of the pressure reducer, which effects a normally indirect adjustment of the opening or closing of the shutter of the reducer, depending on the depth of engagement of its own threaded stem.
  • the adjustment lever of the compensating organ, or the knob for adjusting carbon dioxide pressure being external and quite visible, are too easily accessible to everyone, in particular to non specialised or unauthorised personnel, who could perform adjustments not suitable for a regular dispensing or cause accidental displacements of the lever, with the consequent need frequently to intervene on the adjustments to bring them back to correct parameters.
  • the aim of the present invention is to overcome the aforementioned drawback, making available a device that allows adjustments to be performed only by specialised or in any case authorised personnel, necessarily provided with special adjustment tools or wrenches.
  • the compensating organs are substantially conical elements, positioned along a cone frustum shaped segment (44) of the conduit for the outflow of beer, upstream of the shutter (9) for closing and opening the conduit, commanded by an external knob. In this way they allow to brake and adjust the flow of beer to make it more controllable, varying the outflow port with the simple axial displacement of the compensating organ (4).
  • This displacement is due, in known devices, to the action of a command appendage (31), obtained at an extreme inner side of an element (7) for transmitting the adjustment and engaged in a seat (41) obtained in the compensating organ (4).
  • a command appendage 31
  • the element (7) is inserted, in sealing fashion, in its own seat (38) which extends laterally to the body of the tap (2) and is locked here by an external ring nut (8).
  • the command appendage has an axis that is parallel, but eccentric relative to the axis of the outer end (3) of the element (7), so that the axial displacement of the compensating organ (4) can take place simply by causing the element (7) (and the appendage therewith) about its axis, for a sufficient arc to allow the compensating organ to make a rotary-translatory displacement, where only the translation component is functionally essential.
  • the outer end (3) of the element (7) which in this case coincides with the outer end (1) of the subject device, has a special contour (32), able to couple, rapidly but removably, in a corresponding complementary contour (52) obtained in a tool (preferably constructed specifically for the purpose), which serves as unique and specific wrench (5) for adjusting the compensating organ (4), separate from the tap (2).
  • the presence is in any case preferable, if not essential, of a protecting and armour-plating cap (6), able to be coupled on said end (3) and movable thereon from at least a first extreme position, in which the cap (6), thrust fully on the end (3) and stably engaged thereon, hides and protects the contour (32) from free excess from the exterior, to a second extreme position, in which the cap (6), which is at least partially extracted from the end (3) instead allows free access from the exterior to the contour (32).
  • the regulating device could comprise, in combination with said cap (6), a contour (32) simply provided to be coupled with a corresponding complementary contour (52) of a common tool for the normal adjustment of the compensating organ (4).
  • the subject device advantageously provides for the use of a same unique and specific wrench so shaped as to be also used to allow at least the partial uncoupling of the cap (6) from the end (3) in order rapidly to move it from the first to the second extreme position.
  • the outer end (3) and the cap (6) comprise, the former, an elastic annular element (33) (in this case open, to provide it with greater flexing ability) and the latter at least a corresponding seat (61) for the forced housing of the annular element (33) (or vice versa), for the stable and removable coupling of the cap (6) on the outer end (3), at least in its first extreme position.
  • the preferred contour (32), in the example shown, is the one determined simply by two opposite millings (34, 35) obtained in the body of the end (3), cylindrical shaped in this embodiment, whilst the cap (6), in its first extreme position, covers almost totally the outer end (3), frontally facing, with its free end (63), an underlying external abutment element (88) in this case coinciding with the external ring nut (8) for locking the end (3) itself.
  • the wrench (5) has two tines (51) provided with their own wedge shaped ends (53), to be easily introduced between the cap (6) and the external ring nut (8), when the cap (6) needs to be detached from its first extreme position, uncovering the contour (32).
  • the tines furthermore, are internally distanced in accordance with the distance that separates said millings (34, 35), so that they become engaged between said tines (51), when it is necessary to adjust the compensating organ (4).
  • the tines (51) also present corresponding upper extensions (54), distanced according to the diameter of the cylindrical body of the end, so that the wrench (5) can rapidly detach the cap (6), once the extensions (54) are even partially introduced between cap (6) and external ring nut (8), simply by rotating the wrench (5).
  • a further advantage also stems from the fact that the thickness of the wrench (5) corresponds to the distance between the first and the second extreme position that the cap (6) can assume. If, lastly, the wrench is made of plastic material (as in the case at hand) it may comprise peripheral stiffening ribs (10).
  • the subject device (1) was described applied to compensating organs (4) of taps for dispensing beer, and in particular applied directly onto the outer end (3), accessible by the user, for controlling the adjustment.
  • the protecting element (20) prefferably has axial development at least equal to the maximum excursion of the adjusting screw (12), so that the thread of said adjusting screw (12) is never exposed exteriorly and hence it is particularly well protected.
  • the protecting element (20) may be positioned externally and in sliding fashion to the engagement head (15) of the stem (14) of the adjusting screw (12), as in Figure 7, or internally and in sliding fashion to the engagement head (15) of the stem (14) of the adjusting screw, where in this case a seat (21) is provided for housing the protection element (20). Its stable positioning may for instance be obtained by means of a Seeger ring (22) which makes it axially constrained to the screw (12), in correspondence with a corresponding annular seat (16).
