My version of jsr's syringe valve

Unread postAuthor: jor2daje » Fri Jan 16, 2009 6:36 pm

I saw JSR's syringe valve and I was incredibly impressed and decided i would have to try making one my self. The only problem was I only had very small 2mL syringes. I did not have space for for the air source so i made it sort of inline, see pictures for clarification.

I made this valve to be used with my plinker that I made several weeks ago. This valve is still a prototype but it works really well and now my plinker is basically semi-auto.\

All credit for this design definetly goes to JSR for his syringe valve.

This is my small syringe valve, it is attached to the cap that screws onto my plinker.

This is my valve in Paint, the purple dots are the high pressure air, the blue tube has holes to allow the air out, but the end is blocked with the yellow epoxy so no air goes directly to the barrel. The large pink area is the plunger, the air pressure pushes this forward and air is allowed down the brown tube which pushes a bb forward and then fires.

You can tell how awesome a cannon is by the pressure used.
