DEVICE FOR DOSING AND POURING AN AMOUNT OF GROUND COFFEE POWDER INTO A COFFEE FILTER OF A COFFEE-MAKING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/166312
Kind Code:
A1
Abstract:
The invention relates to a hand-operated device for dosing and pouring an amount of ground coffee powder into a coffee filter of a coffee-making apparatus. The device comprises a dosing valve and means for actuating said dosing valve. The dosing valve comprises a valve body (2) containing two superimposed conical valve elements (5, 6) with downward facing concavity, each of said valve elements (5, 6) having two symmetrical and opposite openings. Said means for actuating said dosing valve consist of a gear mechanism capable of rotating said valve elements (5, 6) one relative to the other, in a reversible manner, from an open valve position, in which said openings in said valve elements (5, 6) are at least partially superimposed and allow the passage of said amount of ground coffee powder, to a closed valve position, in which said openings in said valve elements (5, 6) are staggered and prevent the passage of said amount of ground coffee powder. The gear mechanism includes a support (1) fixed transversely inside said valve body (2), a first rod (4) mounted centrally and axially inside said valve body (2) on said support (1) and having a pinwheel, and a second rod (3) mounted transversely inside said valve body (2) and orthogonally to said first rod (4), and having a pinwheel that engages said pinwheel of said first rod (4). The valve elements (5, 6) are mounted on said first rod (4) so that the lower valve element (6) rotates together with said first rod (4), while the upper valve element (5) is free, but can be driven into rotation by said lower valve element (6) by means of a pin (5a) protruding from its lower part which engages with said lower valve element (6) when said valve elements (5, 6) have been brought into the closed valve position. The second rod (3) has one end protruding externally from said valve body (2) and supporting a control element (9) of said gear mechanism.
