Embodiment

The utility model is further described with reference to the accompanying drawings and examples.

As shown in figs 1 to 6, the utility model includes nut head 1, intermediate mass 4, filter core 7, filter core sleeve 8 and signalling generator, The upper opening of filter core sleeve 8, the inside of filter core sleeve 8 is cavity, and the bottom of filter core sleeve 8 is communicated with the fuel feed hole of cavity 11, fuel feed hole 11 is hexagonal hole, and the filter core 7 is arranged on cavity bottom, multiple filter bores are uniformly provided with the side wall of filter core sleeve 8 12, the intermediate mass 4 is threadably mounted at cavity upper inside wall, and the 3rd sealing ring 6 is provided between intermediate mass 4 and cavity inner wall, in Between the bottom of block 4 and the top of filter core 7 be in close contact, the height sum of the filter core 7 and intermediate mass 4 is equal to the height of cavity, filter core At the upper opening of sleeve 8 the 4th sealing ring 10, filter core sleeve 8 are provided with the seal with screwed joint of hex nut head 1, nut head bottom In the middle part of outer wall and bottom is equipped with annular seal groove 13, and the first sealing ring 9 is provided with seal groove 13.

The signalling generator includes spring 2 and cone valve 3, is provided with groove in the middle part of the lower surface of nut head 1, the bottom land of groove is set There is the through hole of insertion nut head 1, the interface channel 14 of groove and filter core 7 is communicated among intermediate mass 4, cone valve 3 is that upper end is small Lower end big structure, the lower end of the cone valve 3 are inserted in interface channel 14, set between the inwall of the bottom of cone valve 3 and interface channel 14 There is the second sealing ring 5；The upper end of cone valve 3 is through groove and is extend out to from through hole outside nut head 1, and the upper end of the spring 2 is fixed On the bottom land of groove, the lower end of spring 2 is fixed on the middle part of cone valve 3.
