| 1. A device for preparing a coffee-based drink by extracting a dose of ground coffee contained in a capsule, said device comprising
a water tank,
a pump,
a heater body, and
a water injection member connected successively via a water inlet pipe;
said device also comprising, disposed in an extension of the water injection member, a capsule-carrier and an outlet orifice
for a water-coffee mixture, the capsule-carrier being suitable for being manually attached to and removed from the device
and comprises means for containing a capsule of coffee, so that the pressurized water originating from the water injection
member can pass through the capsule and pass through the outlet orifice,
said device also comprising a single branch pipe, said branch pipe being connected at one of its ends to the water inlet pipe
and comprises, at the other of its ends, hydraulic means suitable for controlling the outflow of a water-coffee mixture through
the outlet orifice; and
said device also comprising a valve placed on the branch pipe, said valve being suitable either to be open and allow the water
to flow into the branch pipe when a preset pressure is reached, or closed and close off any flow in the branch pipe when said
preset pressure is not yet reached.
