Abstract

The invention discloses an exhaust type fuel filter element assembly applied to an automobile filter, which comprises filter paper, a central pipe, an upper end cover (5) and a lower end cover (9), wherein the upper end cover is provided with an extension part (51) as an oil outlet of the upper end cover, a gasket (1) is arranged at the oil outlet of the upper end cover, and a plurality of exhaust holes (52) are arranged on the oil outlet of the upper end cover and matched with the gasket. The gasket is used as a one-way valve, so that the influence of pressure impact of a filtering system on a power pump is prevented, oil in the filtering system is prevented from flowing back to an oil tank through the power pump, oil passages can be separated, and mutual interference is prevented. And the exhaust hole setting of upper end cover makes the inside gaseous accessible of filter this exhaust hole and open the gasket and discharge, reduces the air resistance on filter element group spare upper end cover upper portion, improves filter element group spare utilization ratio, makes whole filter have the filter effect of preferred, guarantees fuel oil system's normal operating. And can effectively prevent flameout caused by excessive air in the oil path.

Description

Exhaust type fuel filter element assembly

Technical Field

The invention relates to a filtering system, in particular to a fuel filter element assembly.

Background

At present, the fuel filter element assembly that fuel filter assembly was used does not have exhaust apparatus, can make the vehicle flame-out because of the too much air of oil circuit easily, also does not set up the check valve, perhaps sets up dedicated check valve structure comparatively complicacy, has the risk that the fuel of filtration system refluxes back to the oil tank.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to overcoming the above-mentioned deficiencies, and to providing an exhaust type fuel filter cartridge assembly having a check valve function and effectively discharging air from an oil path.

The purpose of the invention is realized by the following technical scheme: the exhaust type fuel filter element assembly comprises filter paper, a central pipe, an upper end cover and a lower end cover, wherein the upper end cover is provided with an extending part and serves as an oil outlet of the upper end cover, a gasket is arranged at the oil outlet of the upper end cover, and a plurality of exhaust holes are formed in the oil outlet of the upper end cover and are matched with the gasket.

After the structure of the invention is adopted, the gasket is innovatively designed on the upper end cover to be used as a one-way valve, so that the influence of pressure impact of a filtering system on a power pump can be prevented, if the power pump does not work, oil in the filtering system can be prevented from flowing back to an oil tank through the power pump, and the gasket can also be used for separating oil passages and preventing mutual interference. And the oil outlet of the upper end cover is provided with 28-32 exhaust holes, so that gas in the filter is gathered at the oil outlet of the upper end cover and can be discharged through the exhaust holes and the gasket by opening, and further the air resistance at the upper part of the upper end cover of the filter element assembly is reduced, so that the fuel liquid level can rise to the designed height, the utilization rate of the filter element assembly is improved, the whole filter has a better filtering effect, and the normal operation of a fuel system is ensured. Structurally, an exhaust device (matching of an exhaust hole and a gasket) is added, and flameout caused by excessive air in an oil path can be effectively prevented. The invention has simple structure, simplifies the production process, reduces the development of the die, reduces the manufacturing cost and effectively improves the production efficiency.
