Abstract
This invention relates to coupling devices, particularly to coupling devices for use with pressurized substances, for example, fluids such as liquids, gases, and plasmas; drive assemblies for said coupling devices; and to methods of supplying substances. The coupling device comprises a housing defining a chamber, the housing comprising inlet, outlet, and re-circulation/vent apertures; a valve assembly disposed in the chamber, the valve assembly comprising a valve; and a drive assembly located in the housing and operatively engageable with the valve assembly, wherein the drive assembly comprises a drive member disposed in the chamber; and a second cam member operatively engageable with the drive member and the valve assembly, wherein the second cam member is configured to be displaced by the drive member to cause the operation of the coupling device between uncoupled and coupled conditions, and the valve between the re-circulation/vent and charge conditions in a synchronized fashion.
