Water separation module, fuel oil filtering and separating assembly and assembling method thereof

Abstract

A water separation module (1) in a fuel filter separation assembly (900) for a fuel circulation system of a vehicle is provided, the assembly (900) comprising an assembly housing (950) extending alonga longitudinal axis (L-L), the assembly housing (950) being positionable in a horizontal position in the vehicle and accommodating a filter module (500) for filtering dirty fuel. The water separationmodule (1) may be disposed within the assembly housing (950), is fluidly connected to the filter module (500) and extends along a main axis (X-X) parallel and / or coincident with the longitudinal axis(L-L). The water separation module (1) comprises a separation device (2) and a blocking structure (3) arranged below the separation device (2) so as to prevent separated water from flowing back to the separation device (2). The blocking structure (3) comprises a blocking surface (31), at least a portion of which is inclined with respect to the main axis (X-X) to allow water separated from the fuel oil to flow towards the wall of the blocking surface (31) at the extension starting position.

Description

technical field [0001] The present 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 filtration and separation assembly including the water separation module and an assembly method thereof. Background technique [0002] The invention belongs to the field of automobiles. In particular, the invention relates to an assembly for filtering and separating fuel oil, preferably diesel oil, 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 have the function of filtering the fuel to remove from it any suspended particles and / or impurities that could damage components downstream of the fuel circulation system (such as the engine block or high-pressure pump); th...

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
