It is mobile.
Technical solution as a further improvement of that present invention, the hydraulic cylinder include positioned at the first of the piston side
Cavity and the second cavity positioned at the piston other side, the connecting rod pass through first cavity, the return spring
In second cavity.
Technical solution as a further improvement of that present invention, the piston, which is equipped with, is connected to first cavity and described second
The perforation of cavity.
Technical solution as a further improvement of that present invention, first cavity are interior filled with hydraulic with second cavity
Medium.
Technical solution as a further improvement of that present invention, the hydraulic medium are hydraulic oil.
Technical solution as a further improvement of that present invention, the exhaust valve are equipped with to support consolidating for the hydraulic cylinder
Determine support.
Technical solution as a further improvement of that present invention, the hydraulic cylinder are articulated on the hold-down support.
Technical solution as a further improvement of that present invention, the connecting rod are articulated on the valve.
Technical solution as a further improvement of that present invention, the valve are equipped with a pair of of adjutage, and the one of the connecting rod
End is located at this between adjutage and being articulated in this on adjutage.
Compared to the prior art, the present invention can play certain damping action by hydraulic mechanism, so that valve turns
Dynamic speed is slow, avoids the rapid contact with pedestal, reduces contact dynamics, reduce noise.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of exhaust valve of the present invention.
Specific embodiment
It please join shown in Fig. 1, present invention discloses a kind of exhaust valves 100, can be applied in engine exhaust system, example
In noise reduction packet.The exhaust valve 100 include can relative to the valve 1 that pedestal (not shown) turns on or off and with it is described
The hydraulic mechanism 2 that valve 1 matches.
The valve 1 includes pivot 11, so as to which around the pivot 11 is rotated.In illustrative embodiments of the present invention
In, the valve 1 is additionally provided with a pair of of adjutage 12.
The hydraulic mechanism 2 includes hydraulic cylinder 21, the piston 22 in the hydraulic cylinder 21, compresses the piston
22 return spring 23 and the connecting rod 24 being connected with the piston 22, wherein the connecting rod 24 is connect with the valve 1
Together, the rotation of the valve 1 can drive the connecting rod 24 to move in the hydraulic cylinder 21 with piston 22 simultaneously.
In illustrative embodiments of the present invention, the connecting rod 24 is articulated on the valve 1.One end of the connecting rod 24 is located at
This is between adjutage 12 and being articulated in this on adjutage 12.
The hydraulic cylinder 21 includes being located at the first cavity 211 of 22 side of piston and being located at the piston 22 separately
Second cavity 212 of side.The connecting rod 24 passes through first cavity 211, and the return spring 23 is located at described second
In cavity 212.In illustrative embodiments of the present invention, the piston 22, which is equipped with, is connected to first cavity 211 and described the
The perforation 221 of two cavitys 212.It is (such as hydraulic filled with hydraulic medium in first cavity 211 and second cavity 212
Oil).
In addition, the exhaust valve 100 is equipped with the hold-down support 3 to support the hydraulic cylinder 21.It is illustrated in the present invention
Embodiment in, the hydraulic cylinder 21 is articulated on the hold-down support 3, it is ensured that hydraulic cylinder 21 is to a certain degree
On can move and rotate.
When high-speed flow is blown along arrow, 1 stress of valve rotates backward around pivot 11, at this time connecting rod 24 and work
Plug 22 moves backward together in hydraulic cylinder 21；Hydraulic medium in the second cavity 212 passes through perforation 221 and enters institute
It states in the first cavity 211；Meanwhile return spring 23 is compressed.Hydraulic medium (such as hydraulic oil) has certain stickiness, Neng Gouqi
Make the speed during pushing quickly, therefore will not will not generate and open and close to certain damping action.When air-flow power and return
When spring force is equal, reach balance, and keep stable state.
When air velocity reduces, return spring power is greater than the power that air-flow generates, 22 advance the puck of piston, at this time hydraulic Jie
Matter is moved backward by perforation 221；Valve 1 rotates forward, and the damping action of hydraulic medium makes velocity of rotation slow.Work as valve
When 1 EDGE CONTACT is to pedestal, stop operating.Hydraulic mechanism 2 reaches balance at this time, and hydraulic damping action makes valve 1
It will not open and close back and forth, reduce vibration, reduce noise.
The present invention is acted on using the elastic force of hydraulic damping action and spring, is realized the slow of valve in exhaust system and is opened
The function with slowly closing is opened, itself vibration bring structural noise is reduced.
In addition, above embodiments are merely to illustrate the present invention and not limit the technical scheme described by the invention, to this
The understanding of specification should be based on person of ordinary skill in the field, although this specification is referring to the above embodiments pair
Present invention has been detailed description, still, those skilled in the art should understand that, the technology of technical field
Personnel still can modify or equivalently replace the present invention, and all do not depart from the technology of the spirit and scope of the present invention
Scheme and its improvement should all be covered in scope of the presently claimed invention.
