Coupling for carbon dioxide line in vehicle air conditioning system has elastic elements which react differently to changes in pressure

摘要

The coupling (11) provides a gas-tight connection between two tube sectors (1, 2). The coupling includes elastic elements (e.g. 4, 10) which react differently to changes in pressure. These must include at least one first such element which is relatively insensitive and inelastic, and one second one which is relatively more sensitive and elastic, in front of the first one.
