German Ship Gauge Question

[myshelf]

WW I warships used a hydraulic "rammer" to load the projectiles into the barrels, the elevation of the guns was controlled by hydraulics also.

i also read something about "hydraulic drive" in battleships. meaning the steam turbines powered hydaulic systems that turned the drive shafts.
i'm not sure though if that remark was about WW I or WW II battleships.

I'm pretty certain that steam turbines powered the WWI Battleships. Hydraulic's I guess would come into play with the introduction of oil powered engines and not coal fired boilers.

well, the hydraulics in the drive system would replace the reduction gears.

but well, i found something interesting here.

the datasheet states the max pressure in the oxigene cylinder as 150 bar.

did some more checking, looks indeed as if this was the pressure gauge from the oxigene bottle from an aqualung (tauchretter)

Tauchretter? Must've been an u-boat then.

maybe, but engine room crews got them too
