Advantageous effect
In the present invention, the structure of fuel pressure regulator is simple, and part is few, and cost is relatively low.In addition, the fuel pressure regulator has
Have nonmetallic sealing contact surface, so as to avoid under spring force move cylinder according to the Opening pressure point of setting and
In closing and opening process, the noise caused by metal bump, so as to reduce the noise of system.
Description of the drawings
In order to be better understood from the present invention, the present invention is made below by non-limiting example and attached drawing further detailed
Description, wherein：
Fig. 1 is the partial cutaway schematic view according to the fuel pressure regulator of one embodiment of the invention.
Specific embodiment
Referring to Fig. 1, a kind of fuel pressure regulator, including：Upper shell 1 with fuel outlet 9 has fuel inlet 6
Lower casing 5 and the valve member that is arranged between fuel inlet 6 and fuel outlet 9；Wherein the valve member includes：Installation
Bottom end cover 8 on the lower casing 5, the spring 3 being arranged on the upper shell 1 and props up described under the spring 3 effect
The removable cylinder 4 of bottom end cover 8；The nonmetallic fuel resistance being arranged between the bottom end cover 8 and the removable cylinder 4 is close
Sealing 7.The fuel pressure regulator has nonmetallic sealing contact surface, so as to avoid column is moved under spring force
Body closed according to the Opening pressure point of setting in opening process, the noise caused by metal bump, so as to reduce system
Noise.This is simple in structure, and part is few, and cost is relatively low.
The nonmetallic fuel resistance sealing element 7 is made of rubber or other nonmetallic fuel resistance materials.
The fuel gallery 13 connected with the fuel outlet 9 is provided in the removable cylinder 4, the fuel gallery is by institute
Valve member is stated to open and close.When fuel pressure is more than the Opening pressure point set, removable cylinder 4 is moved to unlatching
Position, fuel oil flow to fuel outlet 9 from fuel inlet 6 by fuel gallery 13.
Annular flange 12 is provided on the removable cylinder, which seals with the nonmetallic fuel resistance
7 fitted seal of part, so as to form linear sealing between the removable cylinder and the nonmetallic fuel resistance sealing element.Cause
This, which can obtain preferable sealing effect.
One end of the spring 2 is arranged on the spring base 14 being installed on the removable cylinder, and the other end is arranged on
It is installed on the upper end cover 2 on the upper shell 1.Upper end cover 2 is sleeved on fuel outlet 9.
As shown in Figure 1, upper end cover 2 is equipped with sticking part 15, which is close to shell 1.Specifically, which is
Plate, wherein the inner surface for being close to shell 1 on one side of shell 1, the another side towards lower casing 5 are abutted by spring upwardly.
