摘要: This invention relates to a method and an equipment for portioning of liquid consignments specific amounts the packaging these small in mass production. The is executed with bellows, which defines air space varying volume, that stream caused by bellows establishes injection suction liquid. According connected tip (4), holds confined filter permeable but impermeable When phase sucked into (4) motion liquid, reverse used injecting consignment from tip, certain volume based on corresponding change established controlling bellows. Serial may take place so multiple times after are portioned reversible motions produced be step motor, example. removable, case changed without having clean equipment, since (17) prevents contamination
