Abstract
The utility model provides a bidirectional oil pressure pulsation damper, which comprises an oil inlet pipe, an oil outlet pipe and a casing and is characterized in that a buffering device consisting of two symmetrical membranes and a spring is arranged inside the casing. The membranes divide the casing inside into an upper air chamber, a lower air chamber and a fuel oil chamber. The top ends and the bottom ends of the air chambers are provided with nuts for adjusting spring pressure in the air chambers, and the oil inlet pipe and the oil outlet pipe are located on the same horizontal plane. The bidirectional oil pressure pulsation damper effectively reduces oil pressure pulsation and pulsation noise in a fuel oil pipeline.
Description
Affiliated technical field
The utility model relates to a kind of buffer device, and a kind of two-way hydro pulse buffer is provided.
Background technique
When the oil return plane valve of petrol pump pump oil, oil sprayer injection and oil pressure regulator opens and closes, all will cause the pulsation and the microseismic noise of oil pressure in the fuel pipe, the fuel pressure pulsation makes the work of oil pressure regulator not normal too greatly.
The model utility content
The purpose of the utility model is to provide a kind of two-way hydro pulse buffer, and it can effectively reduce hydro pulse and noise in the fuel pipe.
For realizing that above-mentioned purpose the utility model adopts following technological scheme:
A kind of two-way hydro pulse buffer; Comprise oil inlet pipe, oil outlet tube and housing; It is characterized in that: be provided with the diaphragm of 2 symmetries and the damping device that spring is formed in enclosure interior; Said diaphragm has been divided into last air chamber, following air chamber and fuel oil chamber with enclosure interior, and there is the nut of the indoor spring pressure of adjustable air air chamber top and bottom, and said oil inlet pipe and oil outlet tube are on the same horizontal plane.
When the oil sprayer injected fuel, in conveyance conduit, can produce the fuel pressure pulsation, fuel pressure pulsation vibration damper is to make the fuel pressure attenuate pulsations, to weaken the pressure pulsation transmission in the fuel delivery line, reduces noise.
The beneficial effect of the utility model is:
The damping device that the utility model has adopted symmetrical diaphragm and spring to form, this structure can reduce petrol pump pump oil, oil sprayer sprays and the oil return plane valve of oil pressure regulator when opening and closing, and cause the pulsation and the microseismic noise of oil pressure in the fuel pipe.Even and the buffer structure of the bi-directional symmetrical of symmetry makes the pulsation and the microseismic noise that under the situation that a damping device lost efficacy, also can reduce oil pressure in the fuel pipe through another damping device, improved the stability of motor.
Description of drawings
Fig. 1 is the structural scheme of mechanism of the utility model;
1 is that filler opening, 2 is that oil outlet, 3 is that diaphragm, 4 is that last air chamber, 5 is that air chamber, 6 is that nut, 7 is that spring, 8 is the fuel oil chamber down among Fig. 1.
Embodiment:
A kind of two-way hydro pulse buffer; Comprise oil inlet pipe, oil outlet tube and housing; Be provided with the diaphragm of 2 symmetries and the damping device that spring is formed in enclosure interior; Said diaphragm has been divided into last air chamber, following air chamber and fuel oil chamber with enclosure interior, and there is the nut of the indoor spring pressure of adjustable air air chamber top and bottom, and said oil inlet pipe and oil outlet tube are on the same horizontal plane.
In order to make the pressure pulsation decay, the damping device that has adopted symmetrical diaphragm and spring to form can be reduced to pressure pulsation low-level.Diaphragm separation in vibration damper inside by symmetry is split into overhead air chamber, following air chamber and fuel oil chamber, in air chamber, has spring to be pressed in diaphragm, thereby makes diaphragm produce downward power.When oil pressure in the oil circuit was unstable, this unstable oil pressure acted on the diaphragm, is passed to spring again and is sponged this part power by diaphragm, makes oil pressure become steady.Even and the buffer structure of the bi-directional symmetrical of symmetry makes the pulsation and the microseismic noise that under the situation that a damping device lost efficacy, also can reduce oil pressure in the fuel pipe through another damping device, improved the stability of motor.
