Connector assembly for connecting a source of fluid with a container to be filled

A connector assembly for connecting a source of fluid with a container to be filled with fluid and comprising:

• an elongated tubular body having a fluid passageway extending axially therethrough from an inlet to an outlet so that fluid may enter said inlet and exit from said outlet;
• a depressor located in said passageway intermediate said inlet and said outlet and mounted within said passageway for slidable movement therein between a normally valve closed first position blocking the flow of fluid from said inlet to said outlet and a valve open second position when said depressor is displaced from its said first position toward said second positions;
• a ball valve check assembly located within said body passageway between said inlet and said depressor, said assembly including a spool having a spool passageway extending axially therethrough, said spool passageway having a first passageway portion and a second passageway portion with said second passageway portion being located downstream from said first passageway portion and being of a smaller diameter than said first passageway portion, a radially extending shoulder interconnecting said first passageway portion and said second passageway portion, a resilient ball member having a diameter greater than said second passageway portion but less than said first passageway portion located within said first passageway portion, and spring means for normally resilienting biasing said ball member against said shoulder for preventing passage of fluid through said spool passageway from said first passageway portion to said second passageway portion;
• said depressor having an actuator means extending therefrom toward said ball valve check assembly and extending into said second passageway portion for engaging said ball member and displacing said ball member against the resilient bias of said spring means when said depressor is displaced toward its second position to thereby open said ball valve assembly permitting fluid to flow from said inlet to said outlet;
• and, wherein said spool has a radially inwardly extending annular groove in its outer surface, a resilient O-ring carried in said annular groove for resiliently engaging the surrounding walls of said body passageway for maintaining a fluid tight seal therebetween.
