Abstract
The utility model discloses a kind of fuel pressure regulator, comprise housing, the bottom of described housing is provided with oil outlet, it is characterized in that, diaphragm is provided with in described housing, housing is divided into the spring housing at top and the fuel oil room of bottom by described diaphragm, the spring of pretightening force is provided with in described spring housing, spring is pressed on diaphragm, spring housing is also provided with the breathing pipe be connected with engine throttle suction tude behind the door, the sidewall of described fuel oil room is provided with the filler opening be connected, between described fuel oil room and oil outlet, is provided with scavenger valve.The structure of existing fuel pressure regulator is improved, improves the degree of regulation of regulator, avoid occurring large error.
Description
Technical field
The utility model relates to a kind of fuel pressure regulator.
Background technique
The effect of fuel pressure regulator carrys out regulating system oil pressure according to the change of manifold absolute pressure (MAP), traditional fuel pressure regulator, it adopts regulator bottom centre to extend oil outlet, and the both sides of bottom are provided with a filler opening respectively, and namely regulator has two filler openings, this kind of structure, pressure is easily caused to change greatly, and, because regulator has certain time delay, so, be easy to cause regulating error large.
Model utility content
For the problems referred to above, the utility model provides a kind of fuel pressure regulator, improves the structure of existing fuel pressure regulator, improves the degree of regulation of regulator, avoids occurring large error.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of fuel pressure regulator, comprise housing, the bottom of described housing is provided with oil outlet, it is characterized in that, diaphragm is provided with in described housing, housing is divided into the spring housing at top and the fuel oil room of bottom by described diaphragm, the spring of pretightening force is provided with in described spring housing, spring is pressed on diaphragm, spring housing is also provided with the breathing pipe be connected with engine throttle suction tude behind the door, the sidewall of described fuel oil room is provided with the filler opening be connected, between described fuel oil room and oil outlet, is provided with scavenger valve.
Preferably, described housing is metal shell, such as Stainless Steel Shell.
Preferably, described breathing pipe and filler opening are arranged on the opposed both sides of housing.
During use, pressure regulator is arranged on one end of distribution piping, when oil pressure exceedes presetting force value, spring pressure will be overcome, spill port can be opened by the valve handled by diaphragm, the fuel oil of superpressure is made to flow back into fuel tank, to keep certain fuel pressure, owing to being provided with breathing pipe, the pressure of oil-fired system just depends on the absolute pressure in suction tude (i.e. intake manifold), the injection pressure of oil sprayer can keep constant, do not change with the change of air-distributor pressure, its size equals the pressure of spring, the filler opening that one is positioned at fuel oil room sidewall is only set, improve the degree of regulation of regulator, avoid occurring large error.
The beneficial effects of the utility model are: improve the structure of existing fuel pressure regulator, improve the degree of regulation of regulator, avoid occurring large error.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fuel pressure regulator of the utility model;
The mark implication of accompanying drawing is as follows:
1: filler opening; 2: oil outlet; 3: diaphragm; 4: spring housing; 5: breathing pipe; 6: spring; 7: housing; 8: scavenger valve; 9: fuel oil room.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of fuel pressure regulator, comprise housing 7, the bottom of described housing 7 is provided with oil outlet 2, it is characterized in that, diaphragm 3 is provided with in described housing 7, housing 7 is divided into the spring housing 4 at top and the fuel oil room 9 of bottom by described diaphragm 3, the spring 6 of pretightening force is provided with in described spring housing 4, spring 6 is pressed on diaphragm 3, spring housing 4 is also provided with the breathing pipe 5 be connected with engine throttle suction tude behind the door, the sidewall of described fuel oil room 9 is provided with the filler opening 1 be connected, and is provided with scavenger valve 8 between described fuel oil room 9 and oil outlet 2.
Preferably, described housing 7 is metal shells 7, such as Stainless Steel Shell 7.
Preferably, described breathing pipe 5 is arranged on the opposed both sides of housing 7 with filler opening 1.
In addition, the height of described spring housing 4 is less than the height of fuel oil room 9.Such as, the height of described fuel oil room 9 is 2 times of the height of spring housing 4.
During use, pressure regulator is arranged on one end of distribution piping, when oil pressure exceedes presetting force value, spring pressure will be overcome, spill port can be opened by the valve handled by diaphragm 3, the fuel oil of superpressure is made to flow back into fuel tank, to keep certain fuel pressure, owing to being provided with breathing pipe 5, the pressure of oil-fired system just depends on the absolute pressure in suction tude (i.e. intake manifold), the injection pressure of oil sprayer can keep constant, do not change with the change of air-distributor pressure, its size equals the pressure of spring 6, the filler opening 1 that one is positioned at fuel oil room 9 sidewall is only set, effectively can improve the degree of regulation of regulator, avoid occurring large error.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
