Crankcase ventilation for an internal combustion engine, tank ventilation conduit and connection system therefor

摘要

A crankcase ventilation for an internal combustion engine with a ventilation conduit which connects the crankcase of the internal combustion engine to an intake duct of the internal combustion engine, as well as a tank ventilation conduit and a connection system for a fluid conduit. The ventilation conduit comprises: a first pipe connector (10), and a second pipe connector (20) with a receiving chamber (24) into which the first pipe connector (10) is insertable, wherein a second groove (22) is formed in the receiving chamber (24), and the first pipe connector (10) has a first groove (12), wherein a compressible retaining ring (40) is inserted into the first groove (12), the compressible retaining ring being engageable with the second groove (22) when the first pipe connector (10) is inserted into the receiving chamber (24), or an expandable retaining ring is inserted into the second groove (22), the expandable retaining ring being engageable with the first groove (12) when the first pipe connector (10) is inserted into the receiving chamber (24).

1. A crankcase ventilation for an internal combustion engine with a ventilation conduit that connects the crankcase of the internal combustion engine to an intake duct of the internal combustion engine, the ventilation conduit comprising:
a first pipe connector (10) with an outer surface and a first groove (12) formed in the outer surface, a second pipe connector (20) with an outer surface and an inner surface defining a receiving chamber (24) into which the first pipe connector (10) is insertable, a second groove (22) formed in the receiving chamber (24) and having a depth less than a thickness of the second pipe connector (20) between the inner and outer surfaces, and a compressible retaining ring (40) inserted into the first groove (12) and being engageable with the second groove (22) when the first pipe connector (10) is inserted into the receiving chamber (24), or an expandable retaining ring-is inserted into the second groove (22) and being engageable with the first groove (12) when the first pipe connector (10) is inserted into the receiving chamber (24), whereby the retaining ring (40) is inaccessible when the first pipe connector (10) is inserted into the receiving chamber (24), thereby preventing separation of the first and second pipe connectors (10, 20).
