Title
(EN) NEGATING CHECK VALVE
(FR) CLAPET DE NON-RETOUR DE CONTRE-RÉACTION
Abstract
(EN) A positive displacement pump for dispensing fluid includes a fluid body sub-assembly including a fluid body and a negating check valve. The negating check valve includes a negating body defining a dispensing opening. The fluid body and the negating body form a flow path for the fluid. The fluid is dispensed through the dispensing opening. The positive displacement pump is primed by allowing trapped air within the flow path to flow out of the dispensing opening. The negating check valve may be fully or partially attached to the fluid body. The trapped air within the flow path flows out of the dispensing opening when the negating check valve is partially attached to the fluid body.
(FR) La présente invention concerne une pompe à déplacement positif destinée à distribuer un fluide, ladite pompe comprenant un sous-ensemble de corps pour fluide comprenant un corps pour fluide et un clapet de non-retour de contre-réaction. Le clapet de non-retour de contre-réaction comprend un corps de contre-réaction définissant une ouverture de distribution. Le corps pour fluide et le corps de contre-réaction forment un trajet d'écoulement pour le fluide. Le fluide est distribué à travers l'ouverture de distribution. La pompe à déplacement positif est amorcée en permettant à l'air piégé à l'intérieur du trajet d'écoulement de sortir par l'ouverture de distribution. Le clapet de non-retour de contre-réaction peut être entièrement ou partiellement fixé au corps pour fluide. L'air piégé à l'intérieur du trajet d'écoulement sort par l'ouverture de distribution lorsque le clapet de non-retour de contre-réaction est partiellement fixé au corps pour fluide.
