Abstract
A flexible conduit element with an end portion that is designed for attachment to a rigid conduit element. The flexible conduit includes a bellows member, an interlock member, an outer fixing member and a connection nozzle. An attachment portion of the connection nozzle extends beyond the outer fixing member and the interlock member and ends in a flared shape to form a gas-tight seal.
Claims13
A flexible conduit element (1) configured for use in exhaust systems, comprising:
- a bellows member (2);
- an interlock member (7);
- an outer fixing member (4);
- and
- an connection nozzle (3), wherein
- in an axial cross section at an end portion (10) of the flexible conduit element (1), the outer fixing member (4) is disposed outside of the bellows member (2), the bellows member (2) is disposed outside of the interlock member (7), and the interlock member (7) is disposed outside of the connection nozzle (3),
- an attachment portion (31) of the connection nozzle (3) extends beyond the outer fixing member (4), the bellows member (2) and the interlock member (7), and ends in a flared shape suitable for gas-tight attachment to an exhaust component using a V-clamp or the like, and
- a gas-tight seal connects the bellows member (2) and the connection nozzle (3).
