Abstract
A dispenser for mixing and dispensing a liquid chemical concentrate with a dilutent from a container. The dispenser includes two slideable eductors one of which is also rotatable. Both a high and low flow rate can be obtained with simultaneous adjustment of concentration of the chemical concentrate. The dispenser has a high degree of accuracy of the amount of dilution of the chemical concentrate as well as positive positioning of the high and low flow rate.
Claims65
A dispenser for dispensing different concentrations of chemical concentrate into a stream of water from a concentrate container at different flow rates comprising:
- a body member having a through bore with an inlet end adapted to be connected to a source of pressurized water at one end and an outlet at the opposite end connected to the inlet housing;
- a valve member slideably positioned in the through bore of the body member;
- an eductor slideably and rotatably received in the body member, the eductor in contact with the valve member and in fluid communication with a source of chemical concentrate;
- a trigger member connected to the body member and eductor to cause slideable movement of the eductor;
- the eductor and valve member constructed and arranged to provide control of both different concentrations of chemical concentrate and different flow rates of water and chemical concentrate.
A dispenser for dispensing different concentrations of chemical concentrate into a stream of water from a concentrate container at different flow rates comprising:
- a body member having a through bore with an inlet end adapted to be connected to a source of pressurized water at one end and an outlet at the opposite end;
- a product passage and a vent passage communicating with the through bore;
- an eductor slideably and rotatably received in the through bore;
- and
- a valve member positioned in the through bore for regulating the flow of water through the through bore and the eductor.
