ABSTRACT:
A Bourdon tube pressure gage is employed to monitor operating pressures of machines, such as engines or compressors. The gage has a manually adjustable high pressure limit stop which arrests movement of the gage pressure indicating pointer. A carrier link for a bleeder valve has a lost motion connection with drive mechanism for said pointer, and the carrier link is attached to the movable extremity of the Bourdon tube to be bodily shifted thereby with said vent valve. An abutment on said pointer drive mechanism is in the path of movement of an actuator stem of the vent valve. The pressure chamber of the vent valve is in pressure communication with the low pressure chamber of a booster valve on the back of the pressure gage, said booster valve having low and high pressure input ports and a vent port.
