Me I think (hope!). It's the nearest I'll ever get to the air line
powered gizmo I saw in a tyre/brake place in Welwyn Garden City about 20
years ago: tube attached to bleed nipple at one end and into the bottom
of a reservoir at the other. Airline attached to reservoir in such a
way that the air released across a small orifice in the reservoir
created a vacuum and sucked the brake fluid out of the bleed nipple.
Have I explained that in anything approaching a meaningful way?

A friend of mine (in WGC funnily enough) used to have a vacuum pump that
worked in the same way but you connected it to a tap. You then turned the
tap on and hey presto, one vacuum pump.

the really clever thing is the way steam engine injectors use steam from the
boiler to propel water into the same boiler. It shouldn't be possible.

I'll have to take you word on that, I'm not up on steam engines. Sounds
like one of them perpetual motion thingys that don't exist.

it's dead cunning. the injector uses live steam to accelerate the water and
this moving water has momentum, which extra energy manages to get it into
the boiler. At least that's how I assume it works.

traction engines sometimes have mechanical pumps, which are slower but run
on less steam pressure.
