  • a plate 33 glued or attached against the internal face of an elastic membrane 34 closing the rear part of the valve body 28.
  • the body penetrates by embedding or other connecting means inside an open housing 37, provided in the opposite part 38 of the mixing head 23.
  • the plate 33 On its face opposite to the rod 31, the plate 33 is disposed in the immediate vicinity of the end of a rod 39 carried by the core 40 of an electromagnet 41, immobilized by means (not shown) against the face corresponding to a plate 42 integral with the head 23.
  • the core 40 has outside of the electromagnet 41 a shoulder 43 adapted, when the latter is energized, to come to bear against a bearing 44 , forming a stop and limiting the displacement stroke of the rod 39 which, by pressing on the plate 33 against the spring 35, moves the conical valve 32 to the left, thereby freeing the momentary passage for a quantity appropriate juice or concentrated extract from the container 21 via the nozzle 29 and the transverse passage 30.
  • the juice thus delivered escapes from the valve body 28 to spread into a space 45 formed at the bottom of the housing 37, this space 45 communicating in turn through a hole 46 with a vertical duct 47.
  • a vi s needle 48 with adjustable positioning engages in duct 47 allowing more or less to close the passage at the outlet from hole 46, thereby limiting the flow of juice or extract.
