| 摘要 |
<p>The invention relates to a shut-off device inspection unit (40), which is preferably automatic, for checking the sealing of a shut-off device (32) for liquid fuels, wherein the shut-off device (32) preferably automatically closes or opens a liquid conduit (52) between a first region and a second region of a liquid fuel line for the liquid fuel to which a fuel pressure is applied. The shut-off device inspection unit (40) comprises: a metering chamber (54) which is defined in the liquid conduit (52) between the shut-off device (32) and a preferably automatic closing device (56) and can be separated from the first region by closing the shut-off device (32) and from the second region by closing the closing device (56), a pressure generating device (150) which is connected to the metering chamber (54) for acting on fluid located in the metering chamber (54) with a test pressure which is lower than the fuel pressure, and a pressure sensing device for sensing a pressure change in the metering chamber (54). The invention further relates to uses of such shut-off device inspection units.</p> |
