Abstract
An electro-thermal actuator includes a valve in a partition between a boiler chamber containing the fluid and a variable volume chamber formed in part by a diaphragm. Such valve consists of a bore through the partition which is normally closed by a limited portion of the spring biased diaphragm, the bore being opened when the boiler chamber fluid pressure at the limited diaphragm portion overcomes the spring immediately to expose the entire diaphragm to such relatively high pressure rapidly to drive the same through the expansion stroke.
