Abstract

Un mécanisme de plongeur comprend une soupape de dérivation réglable. En fonction des paramètres de puits, un utilisateur peut souhaiter ajuster la vitesse de descente d'un piston en service. Le présent dispositif permet à l'utilisateur de faire varier ou de régler l'orifice de dérivation pour modifier l'écoulement du liquide à travers le noyau plongeur.
