Q: Was an injector widely adopted as an alternative to mechanical pumps in steam locomotives? ¶
Q: Are injectors therefore typically over 98% energy-efficient overall? ¶
A: Yes, they are also simple compared to the many moving parts in a feed pump.
Q: Were injectors designed to automatically restart on sensing the collapse in vacuum from the steam jet? ¶
A: Yes, for example with a spring-loaded delivery cone.
