摘要: The invention concerns an apparatus for dispensing measured quantities of a liquid or liquefied material, comprising first pumping means, capable of delivering a continuous flow of material, second pumping downstream from said first pumping means, said second pumping means being capable of delivering less than the amount fed thereto by said first pumping means, a recirculation line, connected to the line connecting said first and said second pumping means, said recirculation line being provided with a valve and means for compensating excess of material fed by said first pumping means, which means for compensating excess material are present in said connecting line, and can activate a switch for opening said valve. In order to obviate possible problems concerning contamination by microorganisms, and to provide longer production runs, the invention is characterized in that said means for compensating excess material comprises a membrane which is impermeable for said liquid or liquefield material.

摘要: In packing machines of the type which manufacture packing containers from flexible, tubular material, the contents are fed via a filling pipe opens into the tube. The level of contents in the tube is controlled by means of a float which is connected mechanically to a valve located at the mouth of the filling pipe. On filling of highly viscous types of contents, an arrangement for the control of the flow of contents is used instead, in accordance with the invention, which comprises a sealing device surrounding the filling pipe which on the one hand prevents the contents from penetrating upwards into the tube, and which on the other hand is used for controlling the feed of contents in that its vertical position is monitored by means of a monitoring device surrounding the tube and allowed to control a pump for the feed of contents via the filling pipe.
