Here's a strange question, and excuse my ignorance:

How do these work without a linkage?

Tongue firmly in cheek....very well!

Seriously, they work on the principle of prototype cylinder relief valves. There is a check ball in a chamber that is larger than the ball. When water is present the turbulence in the water keeps the check ball off of its seat allowing the water to be released. Once all of the water and its turbulence is no longer present...the ball snaps up against the seat closing the valve. Full sized railroads used these in conjunction with manually operated cylinder drains. This gave the engineman the ability to open and close the drains when needed. But the relief valves acted as back up in case you had water "carry over" and you had a slug of water enter the cylinders. The relief valves hopefully prevented damage to the cylinders from water carry over.
