Filling level determining device for air hose or tire attached on wheel, has housing formed with mechanical air pressure transmitter and level indicator in valve, where air pressure transmitter is provided with pressure level scale

摘要

The device (1) has a housing (6) formed with a mechanical air pressure transmitter and a pressure level indicator (7) in a valve (2). The air pressure transmitter is provided with a pressure level scale. The housing is firmly fastened at the valve such that a bar (4) is used as a display. The bar is adjusted relative to an unmovable scale (5) by an air pressure difference between the air hose and free atmosphere. The housing is shifted along a stem housing. A scale is attached on the bar as the pressure level indicator. The stem housing is provided with upper and lower springs (9).
