Description
Technical field
The utility model is related to technical field of automobile parts, specifically, is related to one kind and applies in vehicle fuel supply
Fuel pressure regulator in system.
Background technology
Fuel pressure regulator is a critically important parts in vehicle fuel supply system, and it ensure that fuel oil is supplied
Answer pressure in system intermediate fuel oil pipeline within the specific limits so that engine fuel injector has certain pressure in oil spout, this
When sample fuel oil is sprayed onto in combustion chamber, atomizing effect can be more preferable, and burning can be more abundant, reduces tail gas pollution, improves vehicle
Dynamic property.While the too low then fuel injector oil spout too weak or not oil spout of fuel pressure is avoided the occurrence of, and oil pressure is too high, makes oil circuit
The situation that damage or fuel injector are damaged.
A kind of fuel pressure regulator its operation principle applied in the market is as follows：Fuel pressure size passes through spring
It is controlled, when fuel pressure exceeds default standard value, then high pressure fuel can push the circular steel ball shown in left side in figure,
So that the ball valve between steel ball and the housing of pressure regulator is opened, unnecessary fuel oil can be formed by opening after ball valve
Outlet is passed straight back in fuel pump oil storage box；, then can be in initial tension of spring when the low default standard value excessively of fuel pressure
The lower pulling steel ball of effect stops oil return and keeps system pressure stability so as to which ball valve be closed.
But, the fuel pressure regulator has the disadvantage that：1）Steel ball and valve seat are all made up of stainless steel material, by
It is smaller in seal pressure, cause valve port blow-by system not pressurize；2）Noise can be produced when fuel flow is larger.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model is to solve the valve port occurred during fuel pressure regulation
The phenomenon of blow-by system not pressurize, eliminates the noise of high and low frequency, and a kind of fuel pressure regulator of pressure adjustable.
The technical scheme that the utility model is taken to achieve the above object is：
A kind of fuel pressure regulator, the adjuster includes housing, and the housing sets interior diaphragm, and described interior diaphragm will
The cavity of housing cavity formation, which is divided into stilling chamber and fuel oil room, described stilling chamber, is provided with spring base, described
Spring base one end offseted with diaphragm, the other end is by setting spring to be offseted with pressure regulator panel, in described pressure regulator panel
Set in regulating bolt, described fuel oil room and be provided with oil dividing plate, described oil dividing plate offsets with diaphragm, in described oil dividing plate
Portion is provided with the first oil-through-hole, and the first described oil-through-hole is connected with oil inlet, and the circumferential edge of described oil dividing plate is uniformly set
Multiple second oil-through-holes are put, the second described oil-through-hole is connected with fuel oil room, and oil-out is set on described fuel oil room.
As a further improvement, setting pressure gauge on described fuel oil room.
As a further improvement, setting mounting bracket on the adjuster.
The phenomenon for the valve port blow-by system not pressurize that the utility model occurs during fuel pressure regulation, is eliminated
The noise of high and low frequency, and pressure adjustable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model oil dividing plate.
