Kind Code:
B2
Abstract:
The brewing apparatus (2) comprises lateral guiding and holding plates (6, 7) for securing and guiding individual components thereof. A movable brewing piston (39) is guided in a cylindrical guideway (8) provided with an external thread (93). A nut (9) rotatable on the guideway has teeth (10) at its periphery and is moved on the guideway by a motor-driven, elongated gearwheel (11). Lateral guide arms (14, 15) engage the nut and the brewing piston and control the pivoting movement of a brewing cylinder (82). The brewing cylinder has two arms provided with teeth (86, 87), these arms co-operating with a drive part (26) for moving an ejection piston (107) in the brewing cylinder. The drive part for the ejection piston is designed in such a way that it travels only half as far as the ejection piston and thus allows the coffee machine to have less headroom. The displacement of the brewing piston, and hence its brewing position, is electronically detected and makes possible an exact determination of the variable brewing volume, thus optimum adaptation of the brewing chamber to the preselected amount of ground coffee. The drive disposed concentrically with the axis of the brewing piston prevents tilting of the drive facility.
