Description
Technical field
It the utility model is related to a kind of automobile electric fuel pump assembly, more particularly to a kind of electric fuel pump assembly head cover group
Part.
Background technology
Head cover is divided into left and right two by the cap assembly of the prior art using compressed steel spherical structure by pressing steel balls sealing
Separate space.Pressure valve open when or so separate space communicate, fluid leads to housing jet pump by head cover oil nozzle.But it is limited to injection work
Skill, pressing steel balls temperature etc., steel ball sealing easily leaks.In addition, this hard sealing also there are required precision is high, control is difficult,
The problem of of high cost.
Utility model content
The purpose of this utility model is exactly to overcome the deficiencies of the prior art and provide a kind of sealed reliable, simple in structure, cost
Low electric fuel pump assembly cap assembly.
To achieve these goals, the technical solution of the utility model is such：A kind of electric fuel pump assembly
Cap assembly, including head cover and pressure-regulating valve, the head cover are equipped with an oil outlet and an oil inlet, the head cover
In be additionally provided with a cavity, the closing of described cavity one end, one end open, the blind end of the cavity and the oil outlet
Connection, the pressure-regulating valve is in the openend of the cavity insertion cavity, the pressure-regulating valve
End is connected with the cavity as flexible sealing, and the outer end of the pressure-regulating valve is arranged one and makees flexibility with pressure-regulating valve
The gland of sealed connection, the gland are fixedly connected with the head cover, and the gland is equipped with an ejecting port.
The beneficial effects of the utility model are：The pressure-regulating valve of the cap assembly of the utility model and head cover and gland it
Between using flexible sealing connect, will be integrated in into and out of hydraulic fluid port, pressure-regulating valve and ejecting port on head cover, and simplify component
Structure.Have the characteristics that good seal performance, simple in structure, install convenient, using it is reliable, service life is long.
