Abstract
The utility model discloses a fuel pressure regulator, which comprises an upper shell with a fuel outlet, a lower shell with a fuel inlet and a valve component which is arranged between the fuel inlet and the fuel outlet, wherein the valve component comprises a lower end face arranged on the lower shell, a spring arranged on the upper shell, a movable column and a nonmetallic fuel-resistant sealing member; the movable column is pressed against the lower end cover under the action of the spring; and the nonmetallic fuel-resistant sealing member is arranged between the lower end cover and the movable column. The fuel pressure regulator has a nonmetallic sealing contact surface, so that noise caused by metal collision during closing and opening of the movable column according to set opening pressure under the action of spring force is avoided, so that the noise of a system is reduced.
Description
Technical field
The utility model 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 that is used for keeping the oil circuit constant pressure of vehicle.This device is arranged between fuel source and the motor, along carrying fuel oil to the pipeline of 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, need a kind of fuel pressure regulator, this fuel pressure regulator has the structure that reduces noise, and simple in structure, and part is few, and cost is lower.
Summary of the invention
The purpose of the utility model is to provide a kind of fuel pressure regulator, and this fuel pressure regulator has the structure that reduces noise, and simple in structure, and part is few, and cost is lower.
To achieve these goals, the technological scheme of the utility model is following:
A kind of fuel pressure regulator comprises: have the last 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 said lower casing, be arranged on the said removable cylinder of going up the spring on the shell and under this spring action, propping up said lower end cap; Be arranged on the nonmetal fuel resistance Sealing between said lower end cap and the said removable cylinder.
Preferably, said nonmetal fuel resistance Sealing is processed by rubber.
Preferably, be provided with the fuel gallery that is communicated with said fuel outlet in the said removable cylinder, this fuel gallery is opened and sealing by said valve member.
Preferably, an end of said spring is arranged on the spring seat that is installed on the said removable cylinder, and the other end is arranged on and is installed on the said upper end cap of going up on the shell.
Preferably; Between shell between said removable cylinder and the said spring seat and on said and said lower casing; Be provided with Sealing, so that formed space and said fuel inlet between said last shell, said Sealing and the said removable cylinder are isolated.
Preferably, in said valve member downstream, said removable cylinder is provided with the hole that allows fuel oil to flow into said space.
Preferably, said removable cylinder is provided with annular flange flange, this annular flange flange and said nonmetal fuel resistance Sealing fitted seal, thus between said removable cylinder and said nonmetal fuel resistance Sealing, form linear sealing.
Beneficial effect
In the utility model, 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 the spring force effect removable cylinder seal according to the cracking pressure point of setting and opening process in, the noise that metal bump caused, thereby the noise of reduction system.
Description of drawings
In order better to understand the utility model, through non-limiting example and accompanying drawing the utility model is described in further detail below, wherein:
Fig. 1 is the cut-away section schematic representation according to an embodiment's of the utility model fuel pressure regulator.
Embodiment
Referring to Fig. 1, a kind of fuel pressure regulator comprises: have the last 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 said lower casing 5, be arranged on the said removable cylinder 4 of going up the spring 3 on the shell 1 and under these spring 3 effects, propping up said lower end cap 8; Be arranged on the nonmetal fuel resistance Sealing 7 between said lower end cap 8 and the said removable cylinder 4.This fuel pressure regulator has nonmetal sealing contact surface, thus avoided under the spring force effect removable cylinder seal according to the cracking pressure point of setting and opening process in, the noise that metal bump caused, thereby the noise of reduction system.This is simple in structure, and part is few, and cost is lower.
Said nonmetal fuel resistance Sealing 7 is processed by rubber or other nonmetal fuel resistance materials.
Be provided with the fuel gallery 13 that is communicated with said fuel outlet 9 in the said removable cylinder 4, this fuel gallery is opened and sealing by said valve member.When fuel pressure surpassed the cracking pressure point that is provided with, removable cylinder 4 was moved to the enable possition, and fuel oil flows to fuel outlet 9 from fuel inlet 6 through fuel gallery 13.
Said removable cylinder is provided with annular flange flange 12, this annular flange flange 12 and said nonmetal fuel resistance Sealing 7 fitted seal, thus between said removable cylinder and said nonmetal fuel resistance Sealing, form linear sealing.Therefore, this structure can obtain the better seal effect.
One end of said spring 2 is arranged on the spring seat 14 that is installed on the said removable cylinder, and the other end is arranged on and is installed on the said upper end cap of going up on the shell 12.Upper end cap 2 is enclosed within on the fuel outlet 9.
Between shell 1 between said removable cylinder 4 and the said spring seat 14 and on said and said lower casing 5; Be provided with Sealing 11; Going up with said that formed space isolates with said fuel inlet 6 between shell 1, said Sealing 11 and the said removable cylinder 4, thereby make fuel inlet 6 and fuel outlet 9 isolation.
In said valve member downstream, said removable cylinder 4 is provided with the hole 10 that allows fuel oil to flow into said space.Thereby, fuel oil can be from the hole 10 flow into springs 3 places above-mentioned space.
The above; Only be the preferable feasible embodiment of the utility model; The interest field that can not therefore promptly limit to the utility model; Concerning being familiar with those of ordinary skill in the art, use technological scheme of the utility model and technical conceive to make other various corresponding changes and distortion such as, and all these changes and distortion all should belong within the protection domain of the utility model claim.
