Abstract
Complementary couplers useful in providing a coupling through which liquids may be transferred from a first storage reservoir or tank to a second storage reservoir or tank, which can be an on-board fuel tank of a motorized vehicle. There is a first coupling which is configured to be in fluid communication with the interior of a receiving vessel, fuel tank, etc. and a second coupling which is intended to be in fluid communication with the contents of a storage reservoir containing a chemical, liquid fuel, etc. The disclosure also includes a process for charging a fuel reservoir on board of a motorized vehicle from a remote reservoir, wherein the vapor in the fuel reservoir is displaced by an equal volume of fuel delivered from said remote reservoir, and wherein the vapor in said fuel reservoir is simultaneously caused to be transferred to said remote reservoir, thus permitting no escape of the vapor from said fuel reservoir to the surrounding atmosphere. Through use of the present disclosure, more rapid liquid transfer through individual couplers occurs with reduced losses of liquid chemicals, fuel, etc. versus prior art couplers.
