摘要：A beverage brewing machine which has upper (11) and lower (25) brewing chambers which are moveable relative to each other so as to clamp a strip-shaped filter (36) therebetween during the brewing process and the chambers can be separated so as to allow the filter strip to be removed from the brewing chamber and the beverage residual wiped therefrom after which the filter strip is returned to the brewing chambers which are then resealed for the next cycle. A hold down grid (20) engages the top surface of the filter (36) to hold it down as a piston (26) moves in the lower chamber (25) upwardly to force air through the filter to agitate the beverage. When the piston reaches top dead center, the hold down grid (20) is lifted. When the piston passes the opening the brewed coffee is poured. A loose connection is provided between the connecting rod for the piston and the driving crank arm so that the piston remains longer at the top and bottom of its stroke. Due to agitation of ground and oxygenation of the mixture, or a combination of both, by adding a high volume of air during the brewing process, increased extraction results. <IMAGE>
