Title:
MODIFIED PRESSURE BREWING ARRANGEMENT OF THE COFFEE-MAKING MACHINE
Document Type and Number:
WIPO Patent Application WO/2008/122249
Kind Code:
A1
Abstract:
A modified pressure brewing arrangement of the coffee-making machine includes
a first subassembly (1) and a second subassembly (2) constituting the brewing
chamber (3), a driving mechanism driving said first subassembly (1) to open and
close said brewing chamber (3), and a pressure release valve (5). The pressure
release valve (5) has a first coupling opening (50) connected to the brewing chamber
(3), a second coupling opening (51) connected to the boiler of the coffee-making
machine, a pressure release coupling opening (52), and a valve rod (53) which
communicates said first coupling opening (50) with said pressure release coupling
opening (52) in the initial state. A holding block (101) is arranged on said first
subassembly (1). The valve rod (53) is pushed by the holding block (101) during
the period of closing said brewing chamber (3), so that the first coupling opening
(50) is communicated with the second coupling opening (51) and isn't communicated
with the pressure release coupling opening (52).
