Abstract:
1. A system for dispensing a predetermined liquid material from a source container in failsafe controlled manner comprising: a housing for receiving a pressurized fluid stream, said housing having an inlet, an outlet, and an intermediate portion extending therebetween, said intermediate portion having formed therein an admission port for admission of the predetermined liquid material therethrough; a selectively operable valve assembly seated in displaceable manner within said intermediate portion of said housing to selectively activate a flow path between said inlet and said outlet, said valve assembly alternatively opening and closing said admission port responsive to said flow path activation for selective access of the predetermined liquid material into said housing, said valve assembly being operably actuated responsive at least in part to the pressurized fluid stream in said flow path; whereby admission of the predetermined liquid material into said housing is keyed by introduction of the pressurized fluid stream into said flow path with a portion of the pressurized fluid extending from said flow path to pass through a clearance between displaceably opposed surfaces of said valve assembly and intermediate portion.
