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.

Abstract: A connector assembly is disclosed for connecting a source of fluid, such as a refrigerant, with a container, such as in an air conditioning system. The assembly includes an elongated tubular body having a fluid passageway extending axially therethrough from an inlet to an outlet. A depressor is located in the passageway intermediate the inlet and outlet and is mounted for slidable movement between a normally valve closed first position and a valve open second position. A ball valve check assembly is located within the passageway in the tubular body between the inlet and the depressor. This assembly includes a spool having a spool passageway extending axially therethrough. The spool passageway has a first portion and a second portion with the second portion being located downstream from the first portion and being of a smaller diameter. A radially extending shoulder interconnects the first and second portions.

Abstract: A hose assembly is provided having an elongated tubular member having a nipple portion, a hose having an internal diameter corresponding essentially with the outer diameter of said nipple portion and a metallic shell which coaxially surrounds said nipple portion with the hose located therebetween. The shell has a radially inward flange at one end thereof which extends radially into an annular groove located in the tubular portion to prevent axial movement of the shell relative to the nipple portion. The nipple portion has a reduced diameter annular channel having a plurality of axially spaced circumferential barbs which extend radially outward from the channel with the outer diameter of the barbs being less than the outer diameter of the nipple portion.
