Title (EN) PORTABLE FLUID PUMPING DEVICE
(FR) DISPOSITIF PORTABLE DE POMPAGE DE LIQUIDE
Abstract:
(EN) A portable fluid pumping device includes a valve assembly having a pair of one-way umbrella valves (316) controlling the flow of air to produce a positive pressure at one port and a negative pressure at another port. Each umbrella valve includes a valve stem (316c) having a neck (316b) received within the mounting opening (10a), and an umbrella skirt (316a) integrally joined to the neck (316b) to overlie the valve opening (10a). The umbrella skirt (316a) is relatively thin for its complete extent, and the juncture (316a) between the umbrella skirt (316a) and neck (316b) of the valve stem (316c) is of frusto-conical configuration increasing in diameter from the neck (316b) to the umbrella skirt (316a).
(FR) Un dispositif portable de pompage de liquide comprend un ensemble vanne comportant une paire de vannes parapluies à une voie (316) qui commande un flux d'air afin de produire une pression positive à l'un des orifices et une pression négative à l'autre orifice. Chaque vanne parapluie comprend une tige de vanne (316c) pourvue d'un col (316b) qui vient se loger dans une ouverture de montage (10a), et une jupe de parapluie (316a) solidaire du col (316b) et destinée à surplomber l'ouverture de la vanne (10a). La jupe de parapluie (316a) est relativement fine pour qu'elle puisse s'étendre complètement, et le raccord (316a) entre la jupe de parapluie (316a) et le col (316b) de la tige de vanne (316c) a une forme tronconique, son diamètre augmentant en partant du col (316b) en direction de la jupe de parapluie (316a).
