Patent number: 11826682Abstract: Flow control elements (FCEs) and fluid apparatus including the same are described. In embodiments the flow control elements (FCE) include a body that includes a front side, a back side, a left side, and a right side. The body further includes a base region, an upper region, and an intermediate region between the base region and the upper region. The FCE is configured to move in response to a fluid flow (or, more specifically, a pressure differential across the FCE) to regulate a flow of fluid past the FCE. In embodiments the FCE is included in a fluid apparatus for a vehicle, such as but not limited to a suction filter for a vehicle transmission.Type: GrantFiled: August 24, 2021Date of Patent: November 28, 2023Assignee: FILTRAN LLCInventors: Lev Pekarsky, Ibrahim Khalil, Karl S.

Publication number: 20230294025Abstract: A transmission filter includes two outlets. One outlet, adapted to feed an engine-driven pump, protrudes diagonally from the front of the filter. The first outlet is sealed to the inlet of the engine-driven pump by a radial seal. The second outlet is arranged in a rear extension and is sealed to the inlet of an electric pump by a compression seal. The differing types of seals and relative orientations of the outlets make the assembly less sensitive to dimension variation due to production and assembly tolerances. The relative locations of the outlets also mitigate any flow interactions between the pumps when both operate simultaneously.Type: ApplicationFiled: May 22, 2023Publication date: September 21, 2023Inventors: Lev Pekarsky, William Rey Patterson

Publication number: 20200116052Abstract: A transmission oil filter is assembled from a filter element, a base, and a cover. Each of the three pieces extends beyond the filtration media to form an inlet channel. The inlet channel is low enough to fit under a valve body. Placing the inlet in this channel ensures that the inlet draws transmission fluid at road gradients and acceleration rates at which an inlet under the filtration media would draw air.Type: ApplicationFiled: December 6, 2019Publication date: April 16, 2020Inventors: Lev PEKARSKY, Vladimir YASNOGORODSKIY, Akhter ZAMAN

Patent number: 10408332Abstract: A transmission oil filter includes a housing having a bottom cover defining a top side, a bottom side, and an inlet. A filter is disposed in the housing to filter contaminates and fines from the oil passing therethrough. One or more magnets is disposed on the top side surrounding the inlet so that oil passes by the one or more magnets when exiting the inlet to remove and trap fines from the passing oil. The bottom side has ridges disposed under the magnets to trap fines flowing under the housing.Type: GrantFiled: November 22, 2016Date of Patent: September 10, 2019Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Lev Pekarsky, Kent Flory, Ronald P.

Publication number: 20190264588Abstract: During assembly of a transmission, an adapter is installed on a transmission suction filter. The adapter includes a deformable bellows. A top lip of the bellows is attached to the filter inlet while a bottom lip of the bellows includes at least one fin. The fin has a chamfered edge. As two case halves are brought together, the chamfer rubs against a rear case half compressing the bellows. After assembly, the fins control a distance between a sump bottom and the bottom lip of the bellow. As a result, the fluid level can be lower without risking air ingestion.Type: ApplicationFiled: February 23, 2018Publication date: August 29, 2019Inventors: Vladimir Yasnogorodskiy, Lev Pekarsky, David P.

A filter is located upstream of the battery for filtering liquid coolant. The thermal management system also includes a second thermal circuit in fluid communication with the battery thermal circuit. The second thermal circuit provides thermal control to a vehicle system other than the battery. The battery thermal circuit includes a plurality of battery cells. Pluralities of heat exchanger fins are located between each of the battery cells to provide the coolant to regulate the battery temperature. The filter has a filtration transfer function based on a filter characteristic of the fins.Type: GrantFiled: March 1, 2016Date of Patent: July 17, 2018Assignee: Ford Global Technologies, LLCInventors: Lev Pekarsky, David Fabricatore

Patent number: 9764261Abstract: A suction filter for an automatic transmission utilizes two different types of filter media: a coarse filter media and a fine filter media. The two types of media are arranged in series within a housing such that fluid flows through only one of the two filter media. A hinge valve is arranged in series with the coarse media. The hinge valve passively opens in response to a pressure differential. The hinge valve defines a non-zero flow area when in the closed position and an increasing flow area as it opens. The flow restriction associated with the hinge valve permits a larger ratio of coarse media area to fine media, thereby decreasing the flow restriction when the oil is cold without decreasing the clean-up rate in normal operating conditions.Type: GrantFiled: March 19, 2014Date of Patent: September 19, 2017Assignee: Ford Global Technologies, LLCInventors: Kevin E. Norris, Lev Pekarsky

Publication number: 20160341298Abstract: A transmission filter assembly utilizes a filter cartridge that slides axially with respect to the filter chamber. In normal operation, a spring pushes the filter cartridge into a position such that fluid flows into the interior of the cartridge, through filter media, and then radially out of the cartridge. If the pressure drop across the filter is excessive, the pressure forces the filter cartridge to slide to a position in which fluid bypasses the filter media. In this bypass mode, fluid does not flow into the interior of the cartridge and therefore has a very low tendency to dislodge previously captured contaminants. Two sets of tabs position the cartridge radially within the chamber. The two sets are separated axially to prevent tilting of the cartridge.Type: ApplicationFiled: May 21, 2015Publication date: November 24, 2016Inventors: Lev Pekarsky, Vladimir Yasnogorodskiy, Akhter Zaman, Mark Joseph Kane
