®
coffee brewer is structurally composed of four logic
and functional sub-assemblies and some parts for support; there
are four functional assemblies:
1st
025 0014 005R
upper assembly
2nd
025 0014 045R
upper piston
3rd
025 0014 020R
brewer body
4th
025 0014 012
lower assembly
besides serving as a structure for the coffee brewer with the lower
assembly, the upper assembly includes the coffee chute conveying
the ground product to the brewing chamber and the quick coupling
system for the vending machine; some parts connect it with the
lower assembly, thus forming the coffee brewer;
the upper piston works with the brewer body assembly to form and
keep the ground dose during the brew cycle; an o-ring provides for
sealing against the brewing chamber walls and espresso is
dispensed and conveyed into the cup from the outlet on the top of
its structure;
the brewer body assembly consists of the lower piston, the brewing
chamber and the ejection brush of the used dose; the brewing
chamber that is moved by the nut screw is guided by a shaft
intended for vertical sliding;
the ejection brush of the used dose is moved by a ball inserted into
the guide in the side shoulder;
it opposes the upper assembly by accommodating the ends of the
trapezoidally threaded screw and the cylindrical guide moving and
guiding the brewer body; the rear bush of the lower piston rests on
one of its seats to enable the used dose to protrude from the
brewing chamber for ejection;
