 03-04-2016     0-60 Minute Clockwork Compressed Air Release Prototype . 

This is a self contained clockwork timed air valve actuator prototype I have designed for my submarines.

Ive tested the nads off it and it works perfectly, but what the hells it for...? Well the schrader valve on top of the copper tank protrudes through the hull so you can charge it with air from a bike pump. The clockwork timer can be set from 5 to 60 minutes and when the timer runs down a cam on the main drive gear spindle opens a valve releasing the compressed air into the submarines ballast tank making it surface.
