Publication number: 20040216785Abstract: A valve assembly (10) comprises a vortex chamber (14) with an axial outlet port (20), a main inlet port (16) for a fluid to be controlled, and a substantially tangential inlet port (25); the fluid enters through an inlet chamber (13) in which is a mechanical valve (26) movable so as to obstruct fluid flow into the vortex chamber (14). A duct (24) links the inlet chamber (13) to the tangential inlet port (25) of the vortex chamber. The position of the mechanical valve (26) affects the flow of fluid through the duct (24), so the vortex chamber (14) amplifies the effect of the mechanical valve. Further movement of the valve (26) closes off flow altogether (40). The assembly may include a weir (36) in the outlet, to separate gas and liquid phases.Type: ApplicationFiled: October 14, 2003Publication date: November 4, 2004Inventors: Michael Joseph Bowe, John William Stairmand

Patent number: 6655401Abstract: A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.Type: GrantFiled: September 25, 2001Date of Patent: December 2, 2003Assignee: Hydro Systems CompanyInventors: William F.

Patent number: 6619318Abstract: A dispenser for dispensing at two flow rates eductively draws a chemical fluid such as a concentrated cleaning solution for diluting with a motive fluid such as water. Using eduction rather than gravity feed provides a consistent dilution ratio over a range of pressures of the motive fluid. A chemical reservoir contains the chemical fluid and a bottle insert assembly for interfacing to the dispenser. The bottle insert assembly seals an opening to the reservoir when the reservoir is not inserted in the dispenser, preventing leaks. Also, the bottle insert assembly includes dual pickup tubes, each with a purge accumulator, to allow dual rate flow at the same or different dilution ratios as well as drawing back unused chemical fluids from the dispenser to avoid carryover or contamination.Type: GrantFiled: September 25, 2001Date of Patent: September 16, 2003Assignee: Hydro Systems CompanyInventors: Mark D.
