Abstract

A method for automatically feeding a closed liquid system from a liquid source according to need by creating between the liquid source and the closed liquid system a load buffer formed from liquid, in which between the liquid source and the feed buffer only liquid flow in the direction of the feel buffers is allowed and from the feed buffer to the closed liquid system only drorpwise liquid transport is admitted. The feed buffer can be realized with a cylindrical drip feeder with inlet, outlet and freely movable plunger, which can close the outlet in an abutting position while leaving clear a minuscule leakage channel and is provided with a passage with a non-return valve in the direction of the inlet. Such a drip feeder can, with or without insertion of a storage container for liquid, be connected with, for instance, a liquid system, such as a central heating system with pipe system, boiler and expansion tank.

Claims

exact text as granted — not AI-modified
1 : A method for automatically feeding a closed liquid system from a liquid source.  
     
     
         2 : A method according to  claim 1 , characterized in that the feed buffer has a minimum volume.  
     
     
         3 : A method according to  claim 2 .  
     
     
         4 : A method according to  claim 1 .  
     
     
         5 : A drip feeder provided with a cylindrical housing with an inlet.  
     
     
         6 : A drip feeder according to  claim 5 .  
     
     
         7 : A drip feeder according to  claim 6 .  
     
     
         8 : A drip feeder according to  claim 5 .  
     
     
         9 : A drip feeder according to  claim 8 .  
     
     
         10 : A drip feeder according to  claim 5 .  
     
     
         11 : A drip feeder according to  claim 10 .  
     
     
         12 : A drip feeder according to  claim 5 .  
     
     
         13 : A heating installation provided with a closed liquid circulation circuit.  
     
     
         14 : A heating installation according to  claim 10.
