  • Such a compactly constructed canister 3 together with its entire components can be used in a simple manner in the color dispenser 1 and be coupled there, for example, electronically or via the valve-side hose connection 27 with the Dosierkopftechnik 2 flow connected. This results in a total of short flow paths with little hose and pipe connections, in addition, a quick replacement of the canisters 3 is ensured.
  • the multi-way valve 22 is constructed as follows:
  • valve housing 23 In the valve housing 23 ( Fig. 5 ) are exemplary here and preferably three, different flow paths associated with orifices 28, 29 and 30 are provided, which are covered with the interposition of a sealing element 31 of a first fixed orifice plate 32, the mouth openings 28 to 30 associated with and aligned with these recesses 33 to 35 having.
  • This stationary perforated disc 32 is made of a ceramic material, for example.
  • a rotatable perforated disc 36 for example, also made of a ceramic material is arranged, which rests in a planar abutment connection on the stationary perforated disc 32 and.
  • This rotatable perforated disc 36 here has a single disc opening 37, which, as will be explained in more detail below, depending on the valve position in an aligned alignment with the recesses 33 to 35 and thus can be brought to the mouth openings 28 to 30.
  • an upper, for example, made of a plastic material cover 38 is provided, which has an annular collar 39 at the outer edge, which engages behind the rotatable perforated disc 36 state, this so that the cover plate 38 and the rotatable perforated disc 36 are rotationally connected ,
  • an edge-side projection 40 is provided on the rotatable perforated disc 36, which cooperates with the end faces of the annular collar 39.
  • a drive shaft 42 is arranged, in particular integrally formed, which is guided tightly through the two perforated discs 32, 36 and the valve housing 23 and is operatively connected to the valve actuator 24 and its actuator or drive element ,
  • the hose connection 27 is formed by a valve housing side flow channel 43, the valve housing side opens into the orifice 28 and thus forms a first flow path.
  • two flow channels 44, 45 are formed, which face in the assembled state of the narrow side 9 of the canister 3, wherein the both flow channels 44, 45 valve housing side and on the one hand (flow channel 44) in the mouth opening 30 and on the other (flow channel 45) open into the mouth opening 29.
  • 22 different flow paths are formed on the valve housing or the multi-way valve 22.
  • a pipe 46 connected which opens in high axis direction opens into a lower Känister Scheme.
  • a flow in the channel 45 in the Fig. 2 only shown schematically and dashed piping 47 connected, which is guided in the canister 3 upwards and there opens into an upper canister area.
  • rotatable perforated disc 36 is rotated relative to the stationary perforated disc 32, that the disc opening 37 with the recess 33 and thus the mouth opening 30 is aligned and thus in an upward (in the arrow direction) directed displacement of the piston 12 color pigment paste from the canister. 3 is sucked into the pump cylinder 11 (preferably from a lower canister area in the direction of the vertical axis), as shown by the arrow 48. This corresponds to a valve position I.
  • the color pigment paste can be pumped back into the canister 3, in particular into the lower canister area (dotted arrow 48 '), whereby, for example, a sediment can be fluidized.
  • the rotatable perforated disc 36 can also be transferred into a valve position II ( Fig. 6b ), in which the disc opening 37 with a recess 35 of the stationary perforated disc 32 and thus the mouth opening 28 is aligned, so that according to the arrow 49 and a corresponding downward displacement of the piston 12, the color pigment paste from the pump cylinder 11 can be pumped in the direction of dosing unit 2.
  • valve may remain in the valve position II and the piston 12 again be moved upwards accordingly ( Fig. 6c ), whereby possibly in the lines to Dosierkopfiki 2 remaining color pigment paste can be sucked back into the pump cylinder 11 (arrow 50).
  • the canister at one in the operating position shown in the vertical direction of the upper canister end a here substantially over the entire container side extending maintenance opening, which is closable with a closure lid 52.
  • the closure lid 52 overlaps with edge-side tabs 53 the opening edge region and is releasably latched to wall-side locking lugs 54 from opposite longitudinal sides 55 of the canister 3.
  • the canister 3 itself may be made of a plastic material, for example, as well as the valve housing and the housings of the actuators.
