Except wall 211, and damping port is formed between base flange 133 and the end face of peripheral wall 211, and the court of base flange 133
It is configured to inclined-plane to the flange surface of the end face of peripheral wall 211, so that damping port forms gradually expanded form damping port.Gradually expanded form damping port
Setting there is certain barrier effect to water, and when water flow to the top of gradually expanded form damping port, base flange 133 is to water
Has the function of guiding, in order to water outflow.
In some optional embodiments of the utility model, it can also be arranged between top flange 131 and base flange 133
Multiple intermediate flanges 132, intermediate flange 132 and peripheral wall 211 are interference fitted, so as to further promote spool 10 and cock cap
The reliability of 20 cooperations.
In some embodiments of the utility model, cock cap 20 further include: water retaining wall 23, water retaining wall 23 are annular, and
Water retaining wall 23 is connected on the outer peripheral surface of peripheral wall 211, and it is convex that water retaining wall 23 is less than bottom at a distance from the input end of valve core channel 11
The vertical range of the input end of edge 133 and valve core channel 11, i.e. water retaining wall 23 can play good block to base flange 133
Effect promotes the waterproof ability of speed changer breather plug 100 so as to play good barrier action to water.
It is understood that when water slug speed changer breather plug 100 outside speed changer breather plug 100, water retaining wall 23
Play the role of stopping for the first time to water, minimal amount of water enters to the inside of water retaining wall 23, and minimal amount of water is in flaring form drag
The position of Ni Kou can be flowed down by the blocking of base flange 133 along the upper surface of base flange 133, not by base flange
133 water stopped only can just enter at valve core channel 11 upwardly through backwater channel, in the effect of water self gravity
Under flow back along backwater channel, and flowed down along base flange 133, to be effectively prevented the inside that water enters to speed changer,
The speed changer breather plug 100 of this spline structure guarantees under the premise of itself having good venting capability, and it is logical further to promote speed changer
The waterproof performance of vent plug 100.
Optionally, water retaining wall 23 also has certain dustproof effect, can prevent dust from entering.
In some embodiments of the utility model, spool 10 is mounted on the case of transmission of speed changer, referring to Fig.1,
Spool 10 is arranged with sealing element 14, and sealing element 14 can promote the sealing performance between spool and case of transmission.
