SHIPBORNE INDICATING PRESSURE GAGE Russian patent published in 2010 - IPC G01L7/04 

FIELD: measuring equipment.

SUBSTANCE: invention is related to instrument making, namely to indicating pressure gages. Shipborne indicating pressure gage comprises cylindrical case, where holder base is installed, ending with nozzle for connection to measured pressure on external side of case, Bourdon tubular gauge, which is connected with its free end via traction rod to pinion-sector transmission mechanism, which converts motion of free pipe end to circular motion of arrow installed on pinion axis and arranged over dial plate, besides pinion-sector mechanism comprises mechanically joined two joined parallel metal upper and lower plates, which are rigidly fixed on holder base, between which toothed sector is installed as engaged to pinion, on axis of which bush is put with axial hole, and tension flat helical spring is fixed into its slot by its internal end, and by its external end - to pinion-sector mechanism. Besides pinion-sector mechanism comprises protective limiting cup, where hole is available for passage of pinion axis, which is engaged with toothed sector and toothed inertial disk, besides axis of pinion and axis of toothed inertial disk lie in the same plane, and axis of pinion coincides with central axis of pressure gage.

EFFECT: preservation of measurements accuracy, increased vibration stability and reliability of pressure gages operation under shaking conditions.
