Abstract
The utility model provides a fuel oil system high pressure filter relates to the filter field. The filter is characterized in that a filter element body (2) is arranged in a center hole of a filter body (1), a filter screen (4) is arranged in the center hole of the filter element body (2), the filter screen (4) is in press fit with the filter element body (2) through a press cap (5) to form a filter element, and the filter element is sealed with the filter body (1) through a gasket (3). The high-pressure filter of the fuel system is independent of fuel injection parts, has the characteristics of convenience in disassembly and impurity filtering in cleaning, is simple in structure, reasonable in design and convenient to implement, and is suitable for popularization.
Description
Technical field
The utility model relates to the filter cleaner field, relates to a kind of oil-fired system high pressure filter cleaner particularly.
Background technique
In internal-combustion engine manufacturing and using process, because the cleanliness of oil-fired system and fuel oil thereof exists difference, cause the inefficacy of fuel injection system related components, thereby the reliability and the Economy of internal-combustion engine have been reduced, the present filtering means of using, be that the filter core that is press-fitted a radial gap formula in the oil inlet hole of high-pressure injection component carries out filtering, because its structural feature exists the not quick detachable and shortcoming that can't clear up impurity screening after being press-fitted.
Summary of the invention
The purpose of this utility model is a kind of high pressure filter cleaner that is independent of outside the fuel injection component that provides in order to address the above problem, and it is by being provided with filter screen to realize the filtering purpose of oil-fired system high-pressure oil passage in the filter element hole.
The utility model is that a filter core is set in the mesopore of filter housing, filter core is provided with filter screen in the hole, its task is to realize like this, in the mesopore of filter housing 1, be provided with filter body 2, in filter body 2 mesopores, be provided with filter screen 4, filter screen 4 press fit over filter body 2 by pressure cap 5 and constitutes filter core, and filter core is realized sealing by packing ring 3 and filter housing 1.The utility model is because be a kind of high pressure filter cleaner that is independent of outside the fuel injection component, and it is simple in structure, and is reasonable in design, by the application of said structure, realizes the filtering purpose of fuel oil high-pressure oil passage, thereby can improve the reliability and the Economy of internal-combustion engine.
Description of drawings
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the working drawing of the utility model in high-pressure oil passage.
Embodiment
Describe concrete structure and the use condition thereof that the utility model proposes in detail below in conjunction with Fig. 1, Fig. 2.
This oil-fired system high pressure filter cleaner, be in the mesopore of filter housing 1, not have filter body 2, in the mesopore of filter body 2, there is not filter screen 4, filter screen 4 press fit over filter body 2 by pressure cap 5 and constitutes filter core, filter core is realized sealing (as shown in Figure 1) by packing ring 3 and filter housing 1, during use oil-fired system high pressure filter cleaner one end shown in Figure 1 is connected the oil outlet end of going up high-pressure oil pipe 7, the other end connection is gone up the oil inlet end (as shown in Figure 2) of fuel injection component 6 to realize the filtering purpose of fuel oil high-pressure oil passage.Its simplicity of design, reasonable is convenient to implement, and is suitable for popularization.
Claims (1)
