Described pump core carriage and oil cleaner screen scaffold adopt the plastic materials integral molded plastic to be shaped.

Because adopt technique scheme, a kind of fuel screen device of the utility model has following beneficial effect:

1. because a kind of novel fuel filter screen device of the utility model comprises pump core carriage and oil cleaner screen scaffold, oil cleaner screen and oil cleaner screen protecting sheet are installed in oil cleaner screen scaffold bottom, so possess simultaneously the installation pump of accepting core and two kinds of functions of filter fuel.

2. because its pump core carriage of a kind of novel fuel filter screen device and the oil cleaner screen scaffold of the utility model are an overall structure, the oil pumping chamber of pump core carriage bottom has namely been filtered the fuel oil district with the oil strain chamber of oil cleaner screen scaffold and has been communicated, filter fuel oil and can directly enter the pump core, need not other supporting facility accessories, apparatus structure is simple, component reduce, and are conducive to fall low material consumption and processing cost, and are economical and practical.

3. because each part of a kind of novel fuel filter screen device of the utility model adopts the engineering plastics injection molded, oil cleaner screen and oil cleaner screen protecting sheet embed the plastic basic frame gummed again and consist of integral body, and product material has good antiseptic property, long service life.

4. the assembly product design of a kind of novel fuel filter screen device of the utility model and external mounting part composition is symmetric type, compact structure, and volume reduces, instant packed and transportation.

Be further described below in conjunction with the technical characteristics of drawings and Examples to a kind of novel fuel filter screen device of the utility model.
