Abstract

This invention relates to a hydro-pneumatic pressure reservoir of the type comprising a hollow container having a gas port and an oil port, with a deformable partition intervening therebetween defining a gas chamber and an oil chamber. A magnetic switch is mounted externally of the container, and actuating means internally of the container causes actuation of said magnetic switch to give an alarm signal when the volume of gas in the gas chamber falls below a predetermined amount.
