When you press, the cavity is there for pressing spring together with ball. When pressure is released, the spring pushes the ball and in turn all 6 balls turn and we see them rotating. Hence rotation happens
Niigata 6 L 26 HX engines have rotocaps below the spring and both inlet and exhaust valves have such valve rotators. The part numbers are 106 and 107 for Inlet and exh rotocaps, but dimensions are same. ANy idea whats the difference or are they both same, and part numbers do not matter?
Yes, we dismantle it..clean the springs, balls , and race, check for its rotation by compressing manually by hands after boxing back..(simulating the Valve action)
Can u please say when the rotocap will rotate when the rotovanes in 2 stroke will rotate In 4 stroke at what position it will rotate (during opening or closing ) And in 2 stroke when the vanes will rotate ?
There is spring attached on one part fixed., so when spring gets compressed, it pushes balls ahead to nullify the compression. Hence this push becomes a rotation
Can't visualize its working... very complicated😢

Great...now visualization became much easier ✌👍👍
@@CLASS4ORALS yes sirrr!!
As per my knowledge rotocap rotates the valve while closing.
No, During valve opening, by rocker arm force downwards on valve stem, Rotocap rotates & so the valve
No during closing
@@kenikabilanfernando6074 during opening
Turnomats rotate while just about to close, because they are forced through a helix. If they dont rotate, they have to break!
During closing only it rotates the valve not during opening ..
Bro m having a confusion how the ball rotates when belville washer is pressed against the ball?

Is it used on pin type valves
Hi sir, is this not for main engine? Only auxiliary?
No, for the Main Engine we have the wings on the spindle of the Exhaust valve that rotates the valve during exhaust valve opening.
@@abhijeetbanerjee3273 thank you.
On what direction does it rotate while opening and closing
Depends on design
Very nice explanation brother, keep it up.
Thanks alot
Thank you so much ! Rotocap only on exhaust valves? Or is it also on the intake valves?
Most welcome ..👍👍
On Exhaust Valve..so as to remove the built up Soot and carbon deposits..
@@CLASS4ORALS Thank you so much !
@@CLASS4ORALS i have seen rotocaps on intake valves too
@@dajgmqwgdapjdjg its there to give swirl action to air
sir ,does the rotocap need maintainance?
Yes, we dismantle it..clean the springs, balls , and race, check for its rotation by compressing manually by hands after boxing back..(simulating the Valve action)
Explained in very complicated language...
You Understood the topic right? I hope the purpose of video is met. Yet feedbacks are most welcome.😊👍
very good job dear...
Thank u
Can u please say when the rotocap will rotate when the rotovanes in 2 stroke will rotate
In 4 stroke at what position it will rotate (during opening or closing )
And in 2 stroke when the vanes will rotate ?
In 4 stroke - during closing
Best explanation ever👏🏻
Thanks alot
Grt
Thank you
Super ❣️
Thanks alot
Pls, better if with animation
Unfortunately there is no animation for this..
bro not clear explanation
Sorry for that
👌👌
👍👍
Bro didn't understand
Which one
How the motion is being transferred either the spherical balls moves by spring force or any other way around ?
There is spring attached on one part fixed., so when spring gets compressed, it pushes balls ahead to nullify the compression. Hence this push becomes a rotation
