Inhibitor for protecting against misfuelling of diesel-engined vehicle i.e. motor car, by inadvertent filling of petrol, has locking part released from blocking position into filler neck with radial constriction by target filling pipe

摘要

The inhibitor (1) has a check body (6) comprising a target filling pipe (4) that is inserted into a filler neck (3), so that the check body is formed with a threaded-mandrel (7), which is retained by the target filling pipe. The threaded-mandrel includes a clamping region and a radially resiliently displaceable locking part, which is released from a blocking position into the filler neck with a locking part radial constriction by the target filling pipe. The threaded-mandrel has support arms (12) extending from a head part (10) against an opposite locking end.
