Abstract

The safety device for the coffee machine, esp. for use in public places, consists of a piston placed inside a cylinder closed at the top but open at the bottom which is placed over the top of the boiler. The piston is placed in the cylindrical housing and is guided by a rod passing through a pipe in the stopper closing the top of the cylinder. A calibrated spring is positioned between the stopper and the piston and closes two pipes. The two pipes lead from the cylinder base, slightly above the piston. One pipe leads into a nozzle (20) placed in front of the end of the gas burner (21) which heats a thermal strip (22) controlling the gas supply tap (24) of a gas pipe (23). The second pipe leads to a single acting jack (26) which has a piston rod acting in conjunction with a switch controlling the supply of at least one electric resistor placed in the boiler.
