Liquid or pasty product dosage method for simple valve, involves stopping product passage based on closed valve, by realizing rotation of axis, which shifts two orifices, where inner volume of valve remains constant during valve closing

摘要

The method involves passing a liquid/pasty product towards front of a simple valve based on open valve, by aligning one of two orifices on a valve mouth (9) and another orifice on the front of rotation axis, by rotation movement. The product passage is stopped based on closed valve, by realizing rotation of the axis, which shifts the orifices without enabling them to be in opposite. Inner volume of valve remains constant during closing. Independent claims are also included for the following: (A) a method for a recirculation valve for the dosage of liquid or pasty product (B) a simple valve (C) a recirculation valve.
