Built-in manometer for a device for the distribution of fluid under pressure, particularly for a gas expander.

摘要

The pressure gauge (3) is fitted to the body (1) of the gas cylinder by a plug (2) with a seal (10) which fits into a socket (5) in the cylinder. The socket and plug have recesses (6, 7) in their facing surfaces to receive a peg (8), key or pin to hold the pressure gauge in place.
