The popping unit is arranged in the suction channel, where a cross section of the suction channel is expanded for forming the popping unit. A valve (30) has a valve body held in a cage (31), and the smaller cross-section of the suction channel is defined by gaps (33) formed between ribs of the cage and the valve body. The channels are connected with the dosing chamber in an area of external periphery.</p> |
