Abstract: Chemical injector comprises injector structure for injecting a solution from a reservoir into a flowing stream, usually water. The reservoir is at atmospheric pressure, and a chemical solution is withdrawn therefrom by Venturi action, with flow rate being controlled by passage size. Alternatively, an injector pump can positively pump the reservoir solution into the flow stream when the flow rate is too low for Venturi action. A flow control valve is also connected to a bottom portion of the piston of the pump to control the amount of chemical solution flowing from the reservoir to the flowing stream.

Abstract: A container for storing and dispensing a liquid product includes a pump operated by a reciprocable control member and associated with a pneumatic servo system. The actuation is achieved by supply of gas pressure, for example, from a reservoir of gas at a pressure of the order of 5 bars, and this is used to actuate the control member of the pump, for example a stepped piston incorporating a pressure multiplying effect. Much higher operating forces on the reciprocable control member can be achieved with this system than were possible by purely manual operation of the valve control member.

Abstract: A device for mixing and dispensing a flow of liquid concentrated beverage ingredient from a constant volume pump with a pressurized diluent supplied from a source at a preselected flow rate through a flow control device. Diluent flow and liquid concentrate flow intersect and converge into a common fluid passageway which, in turn, flows into a fluid chamber formed by a housing. A tubular spout containing first and second restrictive orifices extends into the chamber formed by the housing and is sealed thereto by a pair of seal rings. The tubular spout can be rotated to a first or second position dependent upon the consistency of the liquid concentrate desired to be dispensed, thereby selectively permitting fluid to flow through the first orifice or both orifices. The unmixed diluent and liquid concentrate in the fluid chamber flow through the orifices and are mixed therein resulting in a homogeneous and uniformly mixed beverage.

Abstract: The invention relates to an apparatus for dosing a liquid product into water, particularly for dosing a liquid detergent product into the water stream fed to domestic washing machines. The apparatus is driven by the water pressure and therefore consists of two hydraulic pressure chambers into which the water is alternately directed. In these chambers two rigidly connected pistons are moved. The pistons are connected to the housing by membrane seals. On one side of the apparatus a pumping part with a pumping chamber is located, into which one of the pistons can move. The pumping chamber is provided with a non-return valve for unidirectionally controlling the flow of the liquid product from a reservoir and with another non-return valve for unidirectionally feeding the liquid product into the water stream in the common outlet pipe. The pistons are connected to an electrically controlled valve assembly for alternatively directing the water stream to one of the two hydraulic pressure chambers.
