Abstract
The invention provides a bidirectional oil pressure buffer, which comprises an oil inlet pipe, an oil outlet pipe and a housing. The bidirectional oil pressure buffer is characterized in that a buffering device composed of two symmetrical membranes and a spring is arranged in the internal of the housing; the internal of the housing is divided into an upper air chamber, a lower air chamber and an oil fuelling chamber by the membranes; screw caps capable of adjusting the spring pressure in the air chamber are arranged at the top end and the bottom end of the air chamber; and the oil inlet pipe and the oil outlet pipe are arranged on the same horizontal surface. The bidirectional oil pressure buffer can effectively reduce the impulse and impulse noise of oil pressure in the oil fuelling pipeline.
Description
Affiliated technical field
The present invention relates to the compression buffer field, a kind of two-way hydraulic 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.
Summary of the invention
The object of the present invention is to provide a kind of two-way hydraulic buffer, it can effectively reduce hydro pulse and noise in the fuel pipe.
For realizing that above-mentioned purpose the present invention adopts following technological scheme:
A kind of two-way hydraulic 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 invention has the beneficial effects as follows:
The damping device that the present invention 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 a structural scheme of mechanism of the present invention;
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 hydraulic 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.
