Abstract: A coupling comprising a first body member and a second body member. The first and second body members are operative to releasably connect together. The first and second body members define a fluid flow path therein when the first and second body members are connected together. The first and second body members are operative to disconnect from one another in response to a predetermined tensile force. At least one valve member is disposed within at least one of the first and second body members and is movable from an open position to a closed position with respect to the fluid flow path upon disconnection of the first body member from the second body member. A sensor is disposed within one of the first and second body members and is operative to sense whether the first and second body members are connected together.

Abstract: An air to liquid regulator valve for use with a vapor recovery system that recovers vapors expelled from a vehicle receiving fuel through a fuel supply passage and returns the vapors to an underground storage tank through a vapor return passage in a service station environment. The regulator valve includes a housing defining a fuel flow path in fluid communication with the fuel supply passage and a vapor return path in fluid communication with the vapor return passage, a vapor return orifice defined by the housing and disposed between a first portion and a second portion of the vapor return path, and a vapor flow bypass in fluid communication with the first portion and the second portion of the vapor return path such that the flow of vapors through both the vapor flow bypass and the vapor return orifice is possible.
