ABSTRACT:
A coffee machine is disclosed which is of the type including a horizontal guide track and a brewing unit mounted for reciprocal movement on the guide track between predefined rest and brewing positions. The machine has first and second slides mounted for sliding movement on the track, a straining unit mounted to the side for movement therewith, a brewing chamber formed integrally with a cylinder that extends above it and a plunger which is axially movable into and out of the cylinder when it is in the brewing position in order to force brewing water into the brewing chamber from the cylinder. The brewing chamber has an open bottom and is mounted to the second slide means in a position above the straining unit for movement therewith. The brewing chamber can be moved into a predefined loading position in alignment with the straining unit into the brewing position together with the straining unit, and into an emptying position in which it is horizontally displaced with respect to the straining unit. Provision is made for lifting the brewing unit prior to introducing relative movement between it and the straining unit in order to avoid excessive wear of the sealing surfaces between them.
