Abstract
A dispenser for mixing and dispensing a liquid chemical concentrate from a container with a dilutent. The dispenser includes a two piece slideable eductor assembly, 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. The dispenser also provides for proper selection of concentrate during operation and has a lock-in feature during operation.
Claims17
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;
- a guide member positioned in the through bore;
- a stop member located on the eductor;
- at least one passage in the stop member for passing over the guide member;
- and
- at least one stop surface for engaging the guide member, the guide member, the stop member and the stop surface constructed and arranged to stop axial movement of the eductor, yet allow axial movement when the passage is aligned with the guide member.

- an eductor slideably and rotatably received in the through bore;
- a guide member positioned in the through bore;
- a stop member located on the eductor;
- at least two passages in the stop member for passing over the guide member, one of the passages including a stop surface;
- at least one stop surface for engaging the guide member, the guide member, the stop member and the stop surface constructed and arranged to stop axial movement of the eductor in one phase, allow a first axial movement when one of the passages is aligned with the guide member in a second phase, and allow a second axial movement when another of the passages with the stop member is aligned with the guide member in a third phase.
