Gas operated automatic, liquid pumping system for wells

   
   

An improved, unattended, liquid pumping device for oil and gas wells featuring a bellows controlled flow valve that opens and closes at preset pressures. Additionally a well head receiver design that releases shut in production gas below the pumping device and provides a positive pressure differential across the pumping device prior to valve opening.

Un dispositif de pompage amélioré, sans surveillance, liquide pour l'huile et les puits de gaz comportant un soufflet ont commandé la soupape d'admission qui s'ouvre et se ferme aux pressions préréglées. En plus une conception principale bonne de récepteur qui libère fermé en gaz de production au-dessous du dispositif de pompage et fournit une différence de pression positive à travers le dispositif de pompage avant l'ouverture de valve.
