SU971415A1 - Filter and separator - Google Patents

Description

The invention relates to devices for the purification of hydrocarbon fuels (gasoline, kerosene, diesel fuel, etc.) from free water and mechanical impurities and can be applied to fuel systems of automobiles, tractors, ships, i.e. where the filter separator housing, in the operating conditions, takes alternately vertical and inclined positions.

A filter separator is known, comprising a housing with inlet, outlet, and drainage nozzles, a filter element comprising filtering, coagulating, drainage and water separating layers, and a bottom cover l.

A disadvantage of the known filter separator when installing it in the fuel system of a vehicle is the low efficiency of fuel dewatering when the car or tractor is moving over rough terrain. The low water separating capacity is due to the fact that the filter separator in the process of operating on the vehicle alternately takes up a vertical and inclined position, as a result of which water separated from the fuel repeatedly Flows from the separator of the filter separator into the working area and back, resulting in to the dispersion of water into small droplets, which are carried away by the flow of fuel from the filter-separator housing to the engine.

The aim of the invention is to increase the efficiency of the filter-separator 10 by eliminating the possibility of water flowing from the sump into the working area when the vehicle is tilted.

This goal is achieved by

15 that the filter separator, comprising a housing with inlet, outlet and drainage nozzles, a filter element including filtering, coagulating, drainage and water-repellent layers, and a bottom cover, is provided with an annular separating partition placed under the bottom cover of the filter element made with annular grooves, the inner of which has

25 through holes, and the outer ones are supplied with gaskets; the bottom cover of the filtering element is made with annular protrusions entering the annular grooves

30 partitions, and through holes of water flow, the filter separator is equipped with an annular separating partition placed under the bottom cover of the filter element, made with annular grooves, the inner of which has through holes, and the outer ones are equipped with sealing gaskets, while the bottom cover of the filter element is made with annular protrusions entering the annular grooves of the partition and through holes, the through openings of the bottom cover and the partitions are aligned and located under the drainage layer.

Claims (1)

Claim A filter separator comprising a housing with inlet, outlet and drainage pipes, a filter element including filtering, coagulating, drainage and water-repellent layers and a lower cover, with the aim of increasing the efficiency of the filter -separator due to elimination of the possibility of overflow of water, the filter separator is equipped with an annular separating partition located under the bottom cover of the filter element, made with annular grooves, the inner of which has through holes, and the outer ones are provided with relative gaskets, wherein the lower cover of the filter element is made with annular protrusions entering into the annular grooves of the partition and through holes, the through holes of the lower cover and partition being aligned and located under the drainage layer.
