| 摘要 |
The invention relates to a testing device for a tire-filling device comprising a housing (10), which has a bottom (11) and an annular outer wall (12) having a cylindrical inner surface (16), a piston (15), which is movably guided and sealed on the cylindrical inner surface (16) and which has an annular contact surface (20) for the tight contact of a filling ring (3) and a central piston opening (19), a spring (26), which is arranged between the bottom (11) and the piston (15) and the spring force of which endeavors to move the piston (15) away from the bottom, and sensors, which sense pressure in an interior (18) that can be filled with compressed gas and which sense the temperature of the housing (10). |
