BREWING DEVICE FOR CAPSULE WITH CLOSURE MECHANISM OF VARIABLE TRANSMISSION RATIO

摘要

Brewing device for the brewing of a capsule containing a beverage ingredient comprising - a main frame (2), - a first capsule holding part (5), - a second capsule holding part (6; 66) for at least partially holding the capsule mobile relative to the first capsule holding part (5) in the frame (2) and linked to the frame by a closing mechanism (23, 31) comprising knuckle joint means or equivalent means; - a manual handle (21) forming lever to activate via the closing mechanism the second holding part from the open position to the closed position and vice versa. The closing mechanism (23, 31) comprises additional force transmission means (31) associated to the handle arranged to de-multiply the force applied by the handle (21; 69) on the knuckle joint means that compensates for the increase of the force needed for closing the holding parts on the capsule.
