Abstract
The invention relates to a fuel pressure regulator which comprises an upper casing, a lower casing and a valve assembly, wherein the upper casing is provided with a fuel outlet, the lower casing is provided with a fuel inlet and the valve assembly is arranged between the fuel inlet and the fuel outlet. The valve assembly includes a lower end cover, a spring, a movable column and a nonmetallic fuel-resistant sealing element, wherein the lower end cover is arrange on the lower casing, the spring is arranged on the upper casing, the movable column is abutted against the lower end cove under the function of the spring, the nonmetallic fuel-resistant sealing element is arranged between the lower end cover and the movable column. The fuel pressure regulator is provided with a nonmetallic sealing contact surface so that the noise caused by the collision of the metals in the process that the movable column closes and opens according to the set opening pressure point under the function of spring force is avoided, and the noise of the system is reduced.
Description
Technical field
The present invention relates to the fuel management systems in a kind of automobile, especially the fuel pressure regulator of fuel management systems.
Background technique
Fuel pressure regulator is a kind of device of the oil circuit constant pressure for keeping vehicle.This device is arranged between fuel source and the motor, on the pipeline along delivering fuel to motor.
Usually, fuel pressure regulator structure relative complex has a lot of parts.In addition, the sealing of fuel pressure regulator tool and unlatching are the collisions of metal to metal, thereby when high frequency ground is opened and sealed, some mechanical shock noises can occur.
Therefore, a kind of fuel pressure regulator need to be arranged, this fuel pressure regulator is with falling low noise structure, and simple in structure, and part is few, and cost is lower.
Summary of the invention
The object of the present invention is to provide a kind of fuel pressure regulator, this fuel pressure regulator is with falling low noise structure, and simple in structure, and part is few, and cost is lower.
To achieve these goals, technological scheme of the present invention is as follows:
A kind of fuel pressure regulator comprises: have the upper shell of fuel outlet, have the lower casing of fuel inlet, and be arranged on the valve member between fuel inlet and the fuel outlet; Wherein this valve member comprises: be installed in the lower end cap on the described lower casing, be arranged on the spring on the described upper shell, and prop up the removable cylinder of described lower end cap under this spring action; Be arranged on the nonmetal fuel resistance Sealing between described lower end cap and the described removable cylinder.
Preferably, described nonmetal fuel resistance Sealing is made by rubber.
Preferably, be provided with the fuel gallery that is communicated with described fuel outlet in the described removable cylinder, this fuel gallery is opened and sealing by described valve member.
Preferably, an end of described spring is arranged on the spring seat that is installed on the described removable cylinder, and the other end is arranged on the upper end cap that is installed on the described upper shell.
Preferably, between shell between described removable cylinder and the described spring seat and on described and described lower casing, be provided with Sealing, so that formed space and described fuel inlet between described upper shell, described Sealing and the described removable cylinder are isolated.
Preferably, in described valve member downstream, be provided with the hole that allows fuel oil to flow into described space on the described removable cylinder.
Preferably, be provided with annular flange flange on the described removable cylinder, this annular flange flange and described nonmetal fuel resistance Sealing fitted seal, thus between described removable cylinder and described nonmetal fuel resistance Sealing, form linear sealing.
Beneficial effect
Among the present invention, fuel pressure regulator simple in structure, part is few, and cost is lower.In addition, this fuel pressure regulator has nonmetal sealing contact surface, thus avoided under spring-force driven dual removable cylinder according to the cracking pressure point of setting seal with opening process in, the noise that metal bump causes, thereby the noise of reduction system.
Description of drawings
For a better understanding of the present invention, below by non-limiting example and accompanying drawing the present invention is described in further detail, wherein:
Fig. 1 is the cut-away section schematic representation of according to an embodiment of the invention fuel pressure regulator.
Embodiment
Referring to Fig. 1, a kind of fuel pressure regulator comprises: have the upper shell 1 of fuel outlet 9, have the lower casing 5 of fuel inlet 6, and be arranged on the valve member between fuel inlet 6 and the fuel outlet 9; Wherein this valve member comprises: be installed in the lower end cap 8 on the described lower casing 5, be arranged on the spring 3 on the described upper shell 1, and prop up the removable cylinder 4 of described lower end cap 8 under these spring 3 effects; Be arranged on the nonmetal fuel resistance Sealing 7 between described lower end cap 8 and the described removable cylinder 4.This fuel pressure regulator has nonmetal sealing contact surface, thus avoided under spring-force driven dual removable cylinder according to the cracking pressure point of setting seal with opening process in, the noise that metal bump causes, thereby the noise of reduction system.This is simple in structure, and part is few, and cost is lower.
Described nonmetal fuel resistance Sealing 7 is made by rubber or other nonmetal fuel resistance materials.
Be provided with the fuel gallery 13 that is communicated with described fuel outlet 9 in the described removable cylinder 4, this fuel gallery is opened and sealing by described valve member.When fuel pressure surpassed the cracking pressure point that arranges, removable cylinder 4 was moved to the enable possition, and fuel oil flows to fuel outlet 9 from fuel inlet 6 by fuel gallery 13.
Be provided with annular flange flange 12 on the described removable cylinder, this annular flange flange 12 and described nonmetal fuel resistance Sealing 7 fitted seal, thus between described removable cylinder and described nonmetal fuel resistance Sealing, form linear sealing.Therefore, this structure can obtain preferably sealing effect.
One end of described spring 2 is arranged on the spring seat 14 that is installed on the described removable cylinder, and the other end is arranged on the upper end cap 2 that is installed on the described upper shell 1.Upper end cap 2 is enclosed within on the fuel outlet 9.
Between shell 1 between described removable cylinder 4 and the described spring seat 14 and on described and described lower casing 5, be provided with Sealing 11, with with 6 isolation of formed space between described upper shell 1, described Sealing 11 and the described removable cylinder 4 and described fuel inlet, thereby make fuel inlet 6 and fuel outlet 9 isolation.
In described valve member downstream, be provided with the hole 10 that allows fuel oil to flow into described space on the described removable cylinder 4.Thereby, fuel oil can be from the hole the 10 above-mentioned spaces that flow into springs 3 places.
The above; only be the better feasible embodiment of the present invention; can not therefore namely limit to interest field of the present invention; concerning those familiar with ordinary skill in the art; such as use technological scheme of the present invention and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong within the protection domain of claim of the present invention.
