Coupling for liquified gases

Abstract

A coupling (1) for liquefied gas comprises a male part (10) and second part (40) to be coupled to each other by insertion of the first part (10) into the second part (40). An internal liquefied gas conduit to be fluidly connected for transfer of liquefied gas through the coupling (1). A valve (42) is movable between a first position, in which transfer of liquefied gas through the coupling is blocked, and a second position, in which transfer of liquefied gas through the coupling is allowed. With the parts (10, 40) interconnected, the coupling has a first operating state in which no liquefied gas is transferred though the coupling and a second operating state in which liquefied gas is allowed to flow through the coupling, By providing least one sensor (14, 16, 20) adapted to sense states of the coupling to enable control the fuelling process, an automated process is provided.
