Pneumatic or hydraulic time delay control
(OP)
Hello, dose any one know if there are any kind of Pneumatic or hydraulic time delay control devices? I am looking for a rotational device that could reset my design after one minute but it is required taht it should be 100% mechanical device and 1 minute timers can´t be found in the market

It will likely have to be a combination of parts, controlled volume, orifice, and pressure switch.

The design is for a mobile application, I was thinking of a rotational device taht would store the tortion energy on a spring and the delay would be acomplished by the passing of fluid through a calibrated nozzle/s but changes in temperature would probably change the viscocity and the timing...
Some automatic water faucets do this by friction I think but need too much maintenance
Any ideas?
