Abstract
The utility model discloses a fuel pump assembly for a metal bracket, which comprises a bracket, a fuel pump fixedly connected onto the bracket, an upper cover flange arranged at the upper end of the bracket, wherein the top part of the upper cover flange is outwards raised to form a mounting cover; an air inlet and outlet valve is fixedly connected into the mounting cover; and an exhaust pipe is connected to the upper part of the mounting cover. In the utility model, since the air inlet and outlet valve is mounted on the fuel pump assembly, the number of opening holes on an oil tank is reduced, and particularly, the air inlet and outlet valve with a valve base and a valve core which are matched with each other can achieve the starting and the closing of an air passage of the air inlet and outlet valve according to fuel level change. When a vehicle is rolled over or the inclination angle of the vehicle exceeds a certain value, the air passage of the air inlet and outlet valve can be closed automatically, so that flue is prevented from flowing out from a pipeline. By adopting the fuel pump assembly, the safety performance of the oil tank is improved, the manufacture is simpler, and the cost is also greatly reduced.

Further be, described air inlet and exhaust valve comprises valve seat, the induction opening that the valve seat bottom is provided with free air diffuser and is communicated with it, the deflation hole that valve seat top is provided with air passage and is communicated with it, the spool that is connected with the spring of valve seat bottom be positioned at free air diffuser and with the valve seat running-fit, spool top can airtightly cooperate with the air passage of valve seat.
Further be, described mounting cup inwall side face is provided with groove, and air inlet and exhaust valve top engages locking along the wedge shape gear ring of periphery wall setting mutually with groove.
Further be, the periphery wall of described air inlet and exhaust valve wedge shape gear ring bottom is provided with the locating convex block that cooperates with the mounting cup bottom, and locating piece is arranged at the air inlet and exhaust valve top.
Further be the mounting cup of described loam cake flange evagination and the mounting cup that is the shaping of loam cake flange one plastic elongation.
Further be that the mounting cup of described loam cake flange evagination and the welding of loam cake flange are connected.
Adopt the utility model, because air inlet and exhaust valve is installed on the fuel oil pump assembly, reduced the perforate on the fuel tank, and the running-fit sealing of air inlet and exhaust valve employing spool and valve seat, air inlet and exhaust valve can be realized the opening and closing to the air inlet and exhaust valve air passage according to the variation of oil level.Rollover or angle of inclination take place when surpassing certain value at vehicle, the air passage of air inlet and exhaust valve also can seal automatically, avoids fuel oil to flow out from pipeline.Adopt this device to increase the safety performance of fuel tank, make simplyr, cost reduces.
