<p>The invention relates to an optical pressure display device with a pointer (3) which is movable mechanically along a display path and can be adjusted according to a control pressure (p), which is applied via a pressure connection (2), to the display of absolute pressure in such a manner that a slow change in pressure brings about an at least partially smooth change in position of the pointer (3), wherein, for the smooth change in position of the pointer (3), a spring-prestressed snap-in mechanism is provided, the snap-in mechanism comprising an adjusting piston (4) which, when a triggering position produced by the control pressure action is reached, brings an actuating means, which is coupled to the pointer (3), to the smooth change in position.</p> |
