US 2023/0067418 A1 · FLOW CONTROL ELEMENTS AND FLUID APPARATUS INCLUDING THE SAME

Abstract

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.
