Patent

CA 2151049

A push-to-connect coupler (20) including an interlocking three-way valve (26) that enables coupling and uncoupling with respect to a mating nipple (21) only when the coupler is in a vent mode. The coupler is characterized by a unique integration of a manually operated three-way ball valve that vents the coupler down to atmospheric or reduced pressure prior to coupling or uncoupling and preferably to a recovery line, a push-to-connect sleeve locking mechanism which interlocks with the manually operated handle of the three-way valve and whose operation is visibly obvious to the user, and an internal valve mechanism (64) that prevents the free flow of media should the coupler become miscocked.
