초록 ▼

A brewing unit comprises a body containing a brewing chamber with vertical axis capable of receiving a pressing plunger mounted mobile along the vertical axis, and a hydraulic jack whereof the piston rod is connected to the pressing plunger and can pass from an inoperative position to a working position, by the effect of a liquid under pressure. The hydraulic jack is a single-acting actuator, the piston rod being returned in inoperative position by compressible and extensible elements. The invention is applicable to espresso coffee brewing machines.
