CO2 Cartridge Mechanism that releases short bursts when triggered
CO2 Cartridge Mechanism that releases short bursts when triggered
(OP)
I am working on a project. I need a mechanism (probably a valve) that releases the Carbon dioxide out of a CO2 cartridge only when a trigger is pressed, and in very short bursts. The mechanism can be no larger than 20mm in length and 8mm in width. Please respond with solutions on the market.

I can see why you have problems, and cannot find any existing commercial product. Nearest would probably be through a supplier of dentist equipment.
Micro check-valves within your measurements and pressure restrictions exist. Perhaps a standard micro check-valve could be modified to suit your purpose?
See for instance attached link.
Suggestion: connect your cartridge to the spring-actuated side of the valve. Cap the front end to make it gas-thigt. Make an outlet opening for released gas in the cap, or near the cap sidewise. Release the gas by adding a hand operated device to force the checkvalve's ball backward to open against the spring and gas pressure. Release the hand operated device (lever? push-button spindle? spring assisted?) and the spring will close the ball, helped by the gas pressure.
