Disconnect valve assembly for connecting a source of fluid with a container to be filled
First Claim
1. A disconnect valve assembly for connecting a source of fluid with a container to be filled with fluid and comprising:
- a tubular body having a fluid passageway extending 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;
a ball-valve check assembly located within said passageway between said inlet and said depressor, said assembly including a stem body slidably mounted within said fluid passageway and having a stem passageway extending therethrough between a stem inlet and a stem outlet, said stem 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 smaller diameter than said first passageway portion, a radially extending valve seat interconnecting said first passageway portion and said second passageway portion, a 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 located in said first passageway portion for normally resiliently biasing said ball member against said valve seat for preventing passage of fluid through said stem passageway from said first passageway portion to said second passageway portion;
said depressor being carried by said stem body and mounted thereon for relative movement with respect thereto downstream from 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 upon relative movement of said depressor and said stem body toward each other for displacing said ball member against the resilient bias of said spring means to thereby open said ball valve assembly permitting fluid to flow from said inlet to said outlet;
means for imparting slidable movement of said stem body in a first direction and in an opposing second direction; and
means for limiting movement of said depressor in said first direction whereupon further movement of said stem body in said first direction causes relative movement of said depressor and said stem body toward each other for displacing said ball member toward said ball valve assembly.

Abstract
A disconnect valve assembly is used to connect a source of fluid with a container to be filled. The valve assembly includes a tubular body having a fluid passageway extending therethrough from an inlet to an outlet. A depressor is located in the passageway intermediate the inlet and the outlet. A ball-valve check assembly is located in the passageway between the inlet and the depressor. This assembly includes a stem body slidably mounted within the passageway. The stem body has a stem passageway extending therethrough including a first passageway portion and a second passageway portion located downstream from the first passageway portion and being of smaller diameter than the first passageway portion. A valve seat interconnects the two portions. A resilient ball member is located in the first passageway portion and a spring serves to normally bias the ball member against the valve seat to prevent passage of fluid therethrough. A depressor is carried by the stem body in a telescoping arrangement therewith. The depressor carries an actuator rod that extends into the stem body for engaging the ball in the ball-valve check assembly. The depressor has a skirt portion having an annular flange which extends radially outward therefrom.
