Interesting stuff from the internet...Huben K1

Unread postAuthor: Gippeto » Sun Aug 14, 2016 1:24 pm

Looking around and came across patent drawings for the K1. Looked like a toolies piston held by a sear... which caught my interest and spurred further digging.

Found a tear down video and actually started chuckling when the fellow showed the firing valve. :lol:

While I'm mot 100% certain, it looks to be eerily similar to JSR's "hammer piston"....with some of the discussion taken into account as well.....

Spudgun "tech" in an airgun....or airgun "tech" in a spudgun...interesting stuff either way. 8)

The working principle of the hammer-less mechanism is as follows:
After the trigger is pulled to release the sear, air pressure pushes the piston backward. Driven by the piston, the air valve opens the air passage and the pellet is propelled out. Then the air passage is cut off by an adjustable shut-off valve. After that, the air pressure pushing the piston backward disappears, and the piston returns to its original position under the force of the spring, thus achieving automatic cocking.

Interesting indeed, nice find!

Funny how I'm reading this right after making a thread asking about mechanically actuated launchers. In my thread I've put up a concept sketch where the chamber pressure is what's opening the valve and after pressure's gone a spring returns the piston to close the valve.
