Brewing unit

A brewing unit for preparing a beverage from a powdered product containing at least one ingredient, the brewing unit comprising

• a support structure comprising an inner cavity, and
• a dispensing assembly that includes
• a first assembly part configured as a drawer insertable into or extractable from a lower part of said inner cavity and comprising a receptacle adapted to receive said powdered product, and
• a second assembly part mounted to slide vertically within an upper part of said inner cavity, between a raised position, in which the second assembly part allows insertion or extraction of the first assembly part, and a lowered position, in which the second assembly part and the first assembly part are coupled to each other to define a brewing chamber therebetween,
• wherein within said first assembly part there is mounted to translate vertically a filtering element through which there is formed a dispensing duct, said filtering element defining a bottom surface of the receptacle and of the brewing chamber, and
• wherein a brewing head adapted to inject water into the brewing chamber is carried by a lower end of the second assembly part, said brewing head defining a top surface of the brewing chamber and being provided with a radial sealing gasket configured to come in contact with a radially inner surface of the receptacle in the lowered position of the second assembly part,
• wherein said filtering element is elastically biased toward an end position thereof which is raised relative to the first assembly part, and
• wherein said filtering element is elastically connected to a driving element vertically translationally movable within said first assembly part, and wherein said driving element is guided by said support structure to move vertically translationally relative to the first assembly part during a sliding motion of the first assembly part into the inner cavity.
