Abstract
The utility model relates to a valve guide pipe, which comprises a pipe body part, wherein a first inner pipe and a second inner pipe communicated with the first inner pipe are arranged inside the pipe body part, and the diameter of the first inner pipe is greater than that of the second inner pipe; and an oil guide hole is further arranged on the pipe body part and is communicated with the first inner pipe. The oil guide hole is arranged on the pipe body part, so that lubricating oil flows into the first inner pipe from the valve guide pipe, and then is dispersed on a friction surface of a valve rod and the valve guide pipe to form an oil film, and thus the lubricating environment is improved.
Description
[technical field]
The utility model relates to a kind of valve guide bushing, belongs to the cylinder technical field.
[background technique]
Valve guide bushing is in-engine important spare part, and it plays a leading role and oil sealing is installed for the valve operating movement.Usually, valve guide bushing is fixed in the cylinder head, and valve guide rod slides up and down in valve guide bushing.The valve guide bushing concrete structure of prior art can be referring to shown in the Figure of description 1, and this valve guide bushing is owing to go into oily lacking in its pipe, and it is too high to add the upper conduit temperature of lower, causes valve guide rod poor lubrication in conduit, thereby causes guide rod and conduit wiping surface damage.
Therefore, in order to solve the problems of the technologies described above, necessaryly provide a kind of structure improved valve guide bushing that has, to overcome described defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of this utility model is to provide a kind of high lubricating effect, and little valve guide bushing rubs.
For achieving the above object, the technological scheme taked of the utility model is:
A kind of valve guide bushing, it comprises a tube body, in described tube body, be provided with in first pipe and with first in pipe is communicated with second in manage, and the diameter of the described first interior pipe is greater than the diameter of the second interior pipe; Further be provided with an oil guiding hole on described tube body, pipe is connected in the described oil guiding hole and first.
Compared with prior art, the utlity model has following beneficial effect:
Valve guide bushing of the present utility model is by being provided with oil guiding hole at tube body, thereby lubricant oil is entered in first in the pipe from valve guide bushing, is distributed to the rubbing surface between valve stem and the valve guide bushing again, and sets up oil film, thereby improve lubricated environment.
[description of drawings]
Fig. 1 is the sectional drawing of the valve guide bushing of prior art.
Fig. 2 is the sectional drawing of valve guide bushing of the present utility model.
[embodiment]
See also shown in the Figure of description 2, the utility model is a kind of valve guide bushing, and it comprises a tube body 1, in described tube body 1, be provided with in first pipe 11 and with first in pipe 11 be communicated with second in manage 12.And the diameter of pipe 11 is greater than the diameter of pipe 12 in second in described first, thereby can make lubricant oil have certain containing space.Further be provided with an oil guiding hole 13 on described tube body 1, pipe 11 is connected in the described oil guiding hole 13 and first.
Valve guide bushing of the present utility model is by being provided with oil guiding hole 13 at tube body 1, thereby lubricant oil is entered from valve guide bushing manages in 11 in first, be distributed to the rubbing surface between valve stem (not shown) and the valve guide bushing again, and set up oil film, thereby improve lubricated environment.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
