Patent number: 11020572Abstract: The device presented is designed to cause, in a mode of operation referred to as “normal” mode, a fluid to flow along this fluid path successively through the first cavity, the filter, the second cavity then the flow restrictor. The device is also designed to cause, in a mode of operation referred to as “purge” mode, a fluid to flow along this same fluid path through the filter but in the opposite direction to the normal flow of the fluid (in the normal mode of operation). Thanks to the “purge” mode, the fluid will detach impurities that have become trapped on the filter in order to clean same.Type: GrantFiled: July 8, 2016Date of Patent: June 1, 2021Assignee: Debiotech S.A.Inventors: Eric Chappel, Dimitry Dumont-Fillon
