Its further technological scheme is: said pedestal is a up-small and down-big cylindrical shell; Its connecting part is a step; Step top is pump core carriage, and the bottom is the oil cleaner screen scaffold, and said pump core carriage comprises carriage housing and carriage cavity; The chamber wall of carriage cavity bottom is provided with the boss of support pump core, and the boss bottom is an oil pumping chamber.

Its technological scheme further is: be evenly equipped with the insertion of being convenient to the pump core and the draw-in groove and the bayonet socket of location on the said carriage housing.

On the open end of said oil strain chamber concave station rank are arranged; Said oil cleaner screen adopts embedded mode to be installed in the concave station rank; The bottom surface of oil cleaner screen embeds and is used for oil cleaner screen protecting sheet that oil cleaner screen is held, and said oil cleaner screen becomes rigid body with the oil cleaner screen protecting sheet with oil cleaner screen scaffold adhesive bond.

The profile of described pedestal is X-X axle and Y-Y axisymmetric body.

Said 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 present invention has following beneficial effect:

1. because a kind of novel fuel filter screen device of the present invention 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 to accept pump core and two kinds of functions of filter fuel are installed.

2. because the present invention's its pump core carriage of a kind of novel fuel filter screen device and oil cleaner screen scaffold are an overall structure; The oil pumping chamber of pump core carriage bottom has promptly been filtered the fuel oil district with the oil strain chamber of oil cleaner screen scaffold and has been communicated, and has filtered fuel oil and can directly get into the pump core, need not other supporting facility accessories; Apparatus structure is simple; Component reduce, and help falling 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 present invention adopts the engineering plastics injection molded, oil cleaner screen and oil cleaner screen protecting sheet embed plastics pedestal gummed again and constitute integral body, and product material has good antiseptic property, long service life.

4. the assembly product design of the present invention's a kind of novel fuel filter screen device and outer part composition is a symmetric type, compact structure, and volume reduces, instant packed and transportation.

Below in conjunction with accompanying drawing and embodiment the technical characteristics of a kind of novel fuel filter screen device of the present invention is further described.
