Anatomy of a Blow off valve anyone?
Hey guys, I'm a mechanical engineering major and unfortunately I'am not boosted and I don't have a BOV. Can anyone with the kindness of your heart who has a HKS bOV take it apart and send me a picture. THANKS!

THanks CUriouz_G. I appreciate your kindness that you used your google skills for me, and thanks for everyone for trying. I already saw the video on the blitz BOV. Now I have a deeper understanding how and why BOV are used. Thanks all.

its a sealed piston with a spring behind it.
You put post throttle vacuum behind the piston, the spring has enough pressure to prevent engine vacuum from opening the valve. Under boost, you have boost pressure (from the vac. line) + spring force behind the piston, and boost pressure on the other side, so the valve stays closed. When you close the throttle, the engine pulls vacuum, but there's still pressure in the pipe... so the valve opens, then once the pressure in the pipe is less than the force exerted by the spring, the piston shuts again... obviously all within a split second.
