Abstract
The utility model provides a bidirectional oil pressure regulator, which has more agile and stable regulation capability by symmetrical pressure regulation units. The bidirectional oil pressure regulator comprises an oil inlet, an oil return hole, pressure regulation units and a fuel oil chamber, wherein each pressure regulation unit comprises a diaphragm, an oil return valve, a vacuum pipe, an air chamber and a spring, and two ends of the air chamber are provided with two symmetrical pressure regulation units.
Description
Affiliated technical field
The utility model relates to the oil pressure regulator field, and a kind of two-way oil pressure regulator is provided.
Background technique
Fuel pressure regulator, it is that the inner fuel pressure of oil-fired system is regulated part, receives the control of system oil pressure and air intake branch pressure (negative pressure).Its effect is that will to keep the fuel pressure of whole pressurized oil system automatically be certain value, makes that the difference of oil pressure and air intake branch pressure is that certain constant (is generally 250～300kPa) in the fuel feeding house steward.When system oil pressure and air intake branch pressure difference changed, fuel pressure regulator can be done corresponding the variation in response to the variation of system oil pressure and air intake branch pressure difference, so that keep intrasystem oil pressure stable.Mostly existing scavenger valve is single pressure regulating unit if adopting.
The model utility content
The purpose of the utility model is to provide a kind of regulating power sensitive, stable more two-way oil pressure regulator.
The utility model is for realizing that above-mentioned purpose adopts following technological scheme:
A kind of two-way oil pressure regulator comprises filler opening, return opening, fuel oil chamber and the pressure regulating unit of being made up of diaphragm, scavenger valve, vacuum tube, air chamber, spring, it is characterized in that: 2 pressure regulating units that are provided with symmetry at the air chamber two ends.
The beneficial effect of the utility model:
The utility model adopts the pressure regulating unit of symmetry for the pressure controlled oil pressure regulator of existing list, make its regulating power quick more, stable.
Description of drawings
Fig. 1 is the structure principle chart of the utility model;
1 filler opening, 2 return openings, 3 diaphragms, 4 scavenger valves, 5 vacuum tubes, 6 air chambers, 7 springs, fuel oil chambers 8 among Fig. 1.
Embodiment
A kind of two-way oil pressure regulator comprises filler opening, return opening, fuel oil chamber and the pressure regulating unit of being made up of diaphragm, scavenger valve, vacuum tube, air chamber, spring, it is characterized in that: 2 pressure regulating units that are provided with symmetry at the air chamber two ends.
When fuel pressure was excessive, 2 scavenger valves were opened simultaneously, flowed into return opening through return opening then, thereby regulated fuel pressure.
