Title (EN) VACUUM OPERATED PUMPS
(FR) POMPES À VIDE
Abstract:
(EN) Examples of vacuum operated pumps are described herein. In an example, a vacuum operated pump includes a plurality of fluid ports, such as an inlet port and an outlet port. The vacuum operated pump may also include a communication port and a diaphragm. The communication port may provide for fluid communication among the plurality of fluid ports. The diaphragm may control the plurality of the fluid ports and the communication port. The diaphragm may mate with the communication port in an idle state of the vacuum operated pump to isolate each of the plurality of fluid ports.
(FR) L'invention concerne des exemples de pompes à vide. Dans un exemple, une pompe à vide comprend une pluralité d'orifices de fluide, tels qu'un orifice d'entrée et un orifice de sortie. La pompe à vide peut également comprendre un orifice de communication et une membrane. L'orifice de communication peut assurer une communication fluidique entre les multiples orifices de fluide. La membrane peut commander la pluralité des orifices de fluide et l'orifice de communication. La membrane peut s'accoupler avec l'orifice de communication dans un état de repos de la pompe à vide pour isoler chaque orifice de la pluralité d'orifices de fluide.
