Abstract:
1. A beverage brewing apparatus, comprising: a cup-shaped body, and a compression piston which engages the cup-shaped body in fluidtight manner and is movable along the cup-shaped body to define, inside the cup-shaped body, an infusion chamber for housing material to be percolated and for receiving pressurized water; a beverage outflow conduit connecting the infusion chamber to the outside, the outflow conduit extending through the compression piston; and a valve located between an inlet portion and an outlet portion of the outflow conduit and formed inside the compression piston, the valve being a three-way valve having an inlet communicating with the infusion chamber via the inlet portion of the outflow conduit, a first outlet communicating with the outlet portion of the outflow conduit, and a second outlet communicating with the outside; wherein the compression piston is a telescopic piston comprising a main body, and a head which is coaxial with the main body along an axis, is connected telescopically to the main body, and is movable, with respect to the main body and along the axis, from a normal extracted position to a withdrawn position in opposition to elastic means; and wherein the three-way valve is a slide valve having a slide face formed on the main body, and a movable part carried by the head, wherein the slide face is defined by a hole formed, parallel to the axis, in the main body; and the movable part is defined by an appendix which is carried by the head, is parallel to the axis, and slides in fluidtight manner inside the hole.
