A plunger mechanism comprising radial peripheral holes extending outwardly from a center core to an outer surface through which a downhole gas may pass to clear an obstruction on the outer surface of the plunger, thereby enabling a self-cleaning action.

Il s'agit d'un mécanisme plongeur comprenant des trous périphériques rayonnants s'étendant vers l'extérieur depuis un noyau central vers une surface externe à travers laquelle un gaz de fond peut passer pour dégager une obstruction sur la surface externe du piston plongeur, permettant ainsi une action auto-nettoyante.
