CRYOGENIC FLUID COUPLING

摘要

A fluid coupling (30) has a male half (32) and a female half (31). Each half has a poppet (35, 42) arranged to move toward and away from a seat (34, 43). The male half (32) has an outer sleeve (38) which is adapted to guide initial joinder of the female half distal end (46). After the two halves have been initially joined, the male half body (39) is extended relative to the sleeve (38) so as to move both poppets (35, 42) off their respective seats and to permit flow through the coupling. The coupling has protrusions (76) provided with sharpened edges which are positioned to scrape ice adhering to facing surfaces when the coupling halves are joined and separated.
