Water separation module, fuel filter separation assembly and assembly method thereof

Abstract

A water separation module (1) used in a fuel filter separation assembly (900) of a fuel circulation system of a vehicle, the assembly (900) includes an assembly housing (950) extending along a longitudinal axis (L-L), the assembly housing ( 950) can be positioned in a vehicle in a horizontal position and houses a filter module (500) for filtering dirty fuel. The water separation module (1) may be disposed within the assembly housing (950) and fluidly connected to the filtration module (500), extending along a major axis (X-X) parallel to and / or coincident with the longitudinal axis (L-L) . The water separation module (1) includes a separation device (2) and a blocking structure (3) arranged below the separation device (2) to prevent separated water from flowing back to the separation device (2). The blocking structure (3) comprises a blocking surface (31), at least a part of which is inclined with respect to the main axis (X-X) to allow the flow of water separated from the fuel oil to extend to the starting point of the blocking surface (31) location wall.

Description

technical field [0001] The invention relates to a water separation module for a fuel filter and separation assembly of a fuel circulation system of a vehicle, and also relates to a fuel filter and separation assembly including the above water separation module and an assembly method thereof. Background technique [0002] The present invention belongs to the field of automobiles. In particular, the present invention relates to a filter separation assembly for fuel, preferably diesel, which is arranged upstream of the combustion chamber of an internal combustion engine. In other words, the fuel output from the filter separation assembly flows to the engine block in the fuel circulation system. [0003] Specifically, these components have a dual function: they filter the fuel to remove any suspended particles and / or impurities from the fuel that could damage components downstream of the fuel circulation system, such as the engine block or the high-pressure pump; they also have...

AI Technical Summary

Problems solved by technology

[0009] However, the fuel filter separation assembly of this horizontal structure has obvious technical defects

[0010] In fact, this assembly is known to be less effective at separating water from fuel oil, but its first drawback is that this assembly presents great difficulties in collecting water

[0011] For these reasons, such known water filtration separation assemblies have very complex and bulky geometries
