Abstract
A connection unit having a connector and at least one fluid line that is connected to the connector, wherein the connector has at least two connection ends and a connector section that connects the connection ends to one another. A fluid line end of a fluid line engages with at least one connection end of the connector. At least one compensation element is connected to the fluid line in the area of the fluid line end of the fluid line, the compensation element being supportable on at least one support stop via at least one spring element. Due to a pressure increase in the connector section, the compensation element is movable against the restoring force of the spring element in the direction of the support stop, with an increase in the internal volume of the connector section.
Claims15
A connection unit having a connector and at least one fluid line that is connected to the connector for conducting an aqueous urea solution, wherein the connector has at least two connection ends and a connector section that connects the connection ends to one another,
- wherein at least one fluid line end of a fluid line engages with a connection end of the connector, wherein in an area of the fluid line end of the fluid line at least one compensation element is connected to the fluid line or to the fluid line end, the compensation element being supportable on at least one support stop via at least one spring element,
- wherein due to a pressure increase in the connector section, the compensation element is movable against a restoring force of the spring element in a direction of the support stop, with an increase in the internal volume of the connector section,
- wherein a connector housing is provided that accommodates the connector, and wherein the at least one fluid line end that engages with a connection end of the connector and the compensation element that is connected in the area of a fluid line end, together with the spring element associated with the compensation element, are accommodated in the connector housing, and
- wherein the compensation element is situated outside the connector and inside the connector housing.
