Abstract

A chamber (4) has accesses (5, 6, 9) to the pressure vessel (1), the gauge (7) and the surroundings. Within the chamber (4) is a valve piston (13) connected to a push-button (10) and restrained by a spring (11). In its normal position, the valve piston (13) allows the pressure in the vessel (1) to be measured by the gauge (7). When the push-button (10) is pressed, one end (16) of the valve piston (13) closes the pipe (5) between the pressure vessel (1) and the chamber (4), and the other end (15) vents the chamber (4) and releases the pressure in the pipe (6) to the gauge and in the gauge (7). The gauge (7) should then read zero.
