Iris valves - GIFs

[PJs]

Wouldn't this wrench tend to tighten with one face (holding tension) and loosen with the other face towards the fastener?

Yes that is correct, it would be like a ratcheting box wrench...by flipping to the opposite face it loosens or tightens.

Stargate SG1 close the iris

[bruce.desertrat]

Beat me to it, LOL! It's the right size, too!

[Radioman]

Just want I was going to say.

It’s for the Stargate of course!

[Loose Ctrl]

Crap! Put me down for the SG1 reference also.

[Frank S]

My reason for suggesting Stargate was looking at the control ring around the iris I could see the chevrons in my imagination
As it turns out this iris has 18 segments while the stargate iris has as near as I can tell 20 segments that was just too uncannily close to being the same plus the size looks too close to being near the same size as the gate iris.
It would be interesting to see the iris in the gif fully closed if the segment points overlapped I would probably loose what little mind i have left.

[JoeVanGeaux]

LOL, "Strargate!" was my instant reaction, as well!!

I just wonder if the cameraman on the lift inside that Stargate knew he was going for a ride?

[Loose Ctrl]

I found the vid with sound.

[Frank S]

Well that leaves out the stargate it seems this iris is nothing more than a throttling flow restrictor.
darn I was hoping for an off world adventure
