Publication number: 20250132449Abstract: An arrangement which includes a connector mounted over an opening of a battery casing, delimiting a gas flow channel. A cover is fitted onto an annular body of the connector to cover the channel in a non-sealing manner, an internal membrane provided in the channel allowing filtration. The axial fitted position of the cover, locked by a locking member, is a position in which: a tip of the cover is placed in the vicinity of the membrane which can thus be torn in the event of critical deformation towards the tip under the effect of an overpressure prevailing against the cover; and the member abuts axially against the connector. The member can deform in order to unlock the fitting of the cover when the overpressure in the channel exceeds a threshold at the time of or after the tearing of the membrane.Type: ApplicationFiled: August 5, 2022Publication date: April 24, 2025Applicant: SOGEFI FILTRATIONInventors: Florent COLLICARD, Jimmy DONETTI, David GUYON

Patent number: 12018785Abstract: A fluidic connection device couples a first end piece of a first tubing/equipment item and a second end piece of a second item/equipment item. The first constitutes a female end piece with a first tubular ending with a smooth internal face, the external face carrying a locking pin or claw. The second end piece constitutes a male end piece with a second tubular ending forming with the first tubular ending a mating part and whose smooth outer face forms a sealed link for the connection with the first tubular ending's smooth inner face. The second end piece includes: a skirt surrounding the mating part; and a spring tongue with a reception housing receiving the pin, locking the first and second end pieces together. The skirt is coupled to a rear part of the second tubular ending by an annular crown forming an introduction stop of the first tubular ending.Type: GrantFiled: October 15, 2020Date of Patent: June 25, 2024Assignee: SOGEFI FILTRATIONInventor: Bruno Le Mouellic

Patent number: 11592067Abstract: The filtration device enables the separation and collection of dust and particles produced by the pads of a brake assembly. A first separation unit having an air filtration medium, typically annular, is provided in the housing of the device, in order to define an upstream zone where air is admitted, for example tangentially, and a downstream zone in communication with an outlet of the housing for discharging the purified air. The upstream zone is in communication with a lower stage situated lower down, in which a second separation unit is located in order to separate water from particles that have fallen from the upstream zone. A filtration by the second unit is intended to collect clean water and possibly to discharge this water by gravitational flow. The fallen particles remain trapped inside the device, under the first unit.Type: GrantFiled: November 2, 2018Date of Patent: February 28, 2023Assignees: SOGEFI FILTRATION, TALLANO TECHNOLOGIEInventors: Nicolas Arnault, Grégory Gauthe

Patent number: 11536171Abstract: The filter for the purification of a liquid of a combustion engine, particularly lubricating oil, includes a housing that has, in a bottom part, an inlet for raw liquid and an outlet for purified liquid, and an unscrewable lid. A cartridge, defined by a filtering insert and a preassembled bypass valve, is received in the housing. The insert has a flange for fixing the valve, covering an end of the filtering medium. The bypass valve can be separated from the cover such that the cartridge can be removed. The valve has a removable connection element that axially engages with a complementary securing component formed on the flange, in a locking configuration obtained by a pivoting action.Type: GrantFiled: March 6, 2018Date of Patent: December 27, 2022Assignee: SOGEFI FILTRATIONInventor: Laurent Fayolle

Patent number: 11338230Abstract: The fuel filter has an outlet for the filtered fuel in a lower base portion of a casing, and a valve associated with the outlet. The filter insert has an internal space in which filtered fuel flows and that accommodates a central member capable of moving the valve to an open position when the insert is in an operational configuration in the casing. The valve is urged, by default, to a sealed position cutting off the flow to the outlet, for example by resilient return arranged between the bottom of the filter and a wall of an interface that guides the lower end of the central member. The central member and the filter insert form a removable unit, and it is therefore possible, typically by way of a cover/removable unit fastening, to automatically obtain the sealed position after opening the top cover.Type: GrantFiled: January 25, 2017Date of Patent: May 24, 2022Assignee: SOGEFI FILTRATIONInventors: Laurent Fayolle, Xavier Lalleman

Patent number: 11105301Abstract: The fuel vapor absorber includes, on a housing member and separately from an air inlet, an orifice for the circulation of fuel vapors coming from a tank. A pipe for supplying these vapors passes through the housing member via the orifice and forms a support for a pressure regulating valve, provided with a valve body and a closure member. The pipe, provided for adaptation between the valve and the housing, is fastened to the housing member, forming at least one annular sealing area surrounding the pipe. The valve, which is fastened by snap-fitting or the like, may be housed in the inside volume of the absorber, where an absorption product is stored. The pipe is typically mounted on the inner face side of the housing member and may be directly welded.Type: GrantFiled: July 20, 2018Date of Patent: August 31, 2021Assignee: SOGEFI FILTRATIONInventors: Benjamin Coton, Farid Ladimat, Baptiste Fonnard, Marouane Sghiouar

Patent number: 10526938Abstract: The arrangement for controlling the flow of laden gases is arranged upstream of an oil separation system and is provided with a check valve, a bypass valve and a stationary segment. The check valve is at least partially movable so as to define a first passage for a forward first flow direction in the event of positive pressure, while the bypass valve is moved rearward by negative pressure so as to clear a second passage for a second, opposite, flow direction. The stationary segment forms a seating surface for the bypass valve. The bypass valve, urged against the seating surface by an elastic biasing member, forms a seat for the check valve. In the event of sufficient negative pressure, the two valves are moved rearward together despite the biasing member and work together to redirect and guide the flow along an escape path corresponding to the second passage.Type: GrantFiled: September 13, 2016Date of Patent: January 7, 2020Assignee: SOGEFI FILTRATION FRANCEInventors: Samuel Bonne, Christophe Petipas, Dominique Oursin
