An arcuate frame (64), the cylinder (6) forms an annular pressing surface (66) on the periphery of the outer end of the trap (62), and the cylinder (6) is further along the conical end of the trap (62). The longitudinal direction of the cylinder (6) is recessed by a receiving hole (68), and the aperture of the receiving hole (68) is slightly larger than the outer diameter of the short column (112) of the main body (11) of the fuel pump, and the receiving hole (68) ) for accommodating the short post (112), the conical groove wall of the trap (62) is used for guiding the respective snap portions (175) of the latching piece (174) of the filter screen (14) to be bent and deformed, and The stub (112) forms a one-way cassette.
將濾網(14)安裝於主體(11)時，首先將套管(163)與入油管(111)套接，且短柱(112)與卡掣片(174)的插孔(176)相對，將柱體(6)靠置於卡掣片(174)，此時，弧形框(64)弧形內緣與撐持環(164)的外周鄰靠，藉此相對定位柱體(6)與撐持環(164)，且壓制面(66)撐持環(164)貼靠，短柱(112)及插孔(176)則與陷槽(62)相對；使用鎚子或其它敲擊工具敲擊柱體(6)的頂端，壓制面(66)迫使撐持環(164)卡掣片(174)向短柱(112)移動，短柱(112)遂相對軸穿插孔(176)，並進入容置孔(68)，插孔(176)周緣的各卡掣部(175)受到短柱(112)的掣動及陷槽(62)的圓錐狀槽壁導引而彎曲變形，而可簡單且快速地完成濾網(14)安裝於主體(11)的操作。 When the filter (14) is mounted on the main body (11), the sleeve (163) is firstly sleeved with the oil inlet tube (111), and the short column (112) is opposite to the insertion hole (176) of the locking piece (174). , the cylinder (6) is placed on the clamping piece (174), at this time, the curved inner edge of the curved frame (64) abuts against the outer circumference of the supporting ring (164), thereby positioning the column (6) relative to each other. With the support ring (164), and the pressing surface (66) supporting ring (164) abuts, the short column (112) and the socket (176) are opposite to the trap (62); tapping with a hammer or other tapping tool At the top end of the cylinder (6), the pressing surface (66) forces the retaining ring (164) to move the tab (174) toward the short post (112), the short post (112) 遂 the relative through the jack (176), and enter The receiving hole (68), each of the latching portions (175) of the periphery of the receiving hole (176) is bent and deformed by the sliding of the short post (112) and the conical groove wall of the trap (62), and can be simply And the operation of installing the filter (14) on the main body (11) is completed quickly.
前述拆卸工具與安裝工具可伴隨使用，欲將過濾功能劣化或喪失的濾網更換，使燃油泵回復正常的泵送燃油能力時，使用拆卸工具將過濾功能劣化或喪失的濾網卸除，使用安裝工具將新的濾網安裝於燃油泵。 The aforementioned disassembly tool and the installation tool can be used together, and if the filter is to be replaced or the filter is lost, and the fuel pump is returned to the normal pumping fuel capacity, the filter is used to remove or remove the filter function. The installation tool installs the new filter on the fuel pump.
