automatic pneumatic coupling device of pipelines of railway vehicles, associated with a mechanism of automatic indexation of the type willison

摘要

Automatic connectors for service conduits associated with automatic railway vehicle couplings are in this invention displaceable relative to the respective coupling heads into engagement with each other in response to the approach of the coupling heads to interengagement, by a mechanical lever system such that the final interengagement of the connectors occurs only after the frontal impact between the coupling heads.
