Broxa nozzel

[Eclipse1]

I have a broxa, and the nozzle is in the back position every time after i shoot in semi. should it be fully forward?

thanks

Nope, the nozzle will settle at various points between shooting. Is because the gear that pulls the piston back has a nub on it that pulls the tappet (and nozzle) back then releases, and if you picture a clock that spins, and the 1 O'Clock on it has the nub, whereever the clock stops spinning the nub will be anywhere around there. Make any sense?

Aka: Don't worry.

yup, but doesn't the position of that gear also dictate how far back the piston, and spring are pulled?

It does, but will always release the piston at the same point, it's the teeth (about half the gear has teeth, the other half doesn't......... is why it's called a sector gear) that pull the piston back that causes the release of the piston itself, has nothing to do with the nub on the gear that does the BB loading and sealing in the breech.

Here's something: If your tappet plate breaks, the nozzle won't move at all and no BBs will get loaded, yet the piston will happily get pulled back and released full power as it always does. They are two separate systems linked together by one dual purpose gear.

Check this moving picture...it helps visualize what's happening...(if I could figure out how to embed the thing I would have....)

Is a great animation, but one thing it doesn't show is that the sector gear stops in various positions due to the anti-reversal latch, which is what I tried to explain to him about his nozzle position.

Oh, you're completely right.

I've never seen a mechbox that actually stops without the first tooth engaged in the piston on semi....LOL

Is there any problem when you shoot the gun? If not why are you asking? LOL. If it's shooting normally then it's working properly.
