a stop member located on the eductor;
at least one passage in the stop member for passing over the guide member; and
a 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 one of the passages is aligned with the guide member.
4. The dispenser of claim 1 wherein the eductor is composed of first and second parts, only one of which is rotatable.
5. The dispenser of claim 3 wherein the first part of the eductor is rotatable and extends from the body member.
6. The dispenser of claim 4 wherein the second part of the eductor is nonrotatable and the first and second parts of the eductor provide a fluid passage with the product passage.
7. The dispenser of claim 5 further including a dilution adjustment member connected to the rotatable eductor for fluid communication with the fluid passage.
8. The dispenser of claim 1 further including a vent passage in the body and a seal constructed and arranged to selectively seal both the product passage and the vent passage.
9. The dispenser of claim 6 wherein the dilution adjustment member includes a multiplicity of different sized passages.
10. The dispenser of claim 1 further including an elongated spout connected to the body, the spout adapted to be hung on a bucket.
11. The dispenser of claim 9 further including a flexible tube member connected to the eductor and the spout.
12. The dispenser of claim 1 further including a spray nozzle connected to the eductor.
13. The dispenser of claim 1 further comprising an actuator coupled to the body to selectively cause slideable movement of the eductor.
14. 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 having a bore adapted to be connected to a source of pressurized water;
a product passage communicating with the bore;
an eductor slideably and rotatably received in the bore, the eductor having a first sliding position in which chemical concentrate cannot be dispensed to into a stream of water and a second sliding position in which chemical concentrate can be dispensed into the stream of water, depending upon the rotational position of the eductor; and
an interlock between the body and the eductor, the interlock allowing rotation of at least a portion of the eductor in the first sliding position of the eductor and preventing rotation of the portion of the eductor in the second sliding position of the eductor.
15. The dispenser of claim 13, wherein the interlock comprises:
a guide member positioned in the bore;
a stop member located on the eductor;
at least one passage in the stop member for passing over the guide member; and
a 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 one of the passages is aligned with the guide member.
16. The dispenser of claim 13 wherein the eductor is composed of first and second parts, only one of which is rotatable.
17. The dispenser of claim 13 further comprising an actuator coupled to the body to selectively cause slideable movement of the eductor.
18. A method of dispensing different concentrations of chemical concentrate into a stream of water from a concentrate container at different flow rates while preventing a change in concentration of flow rate while dispensing, the method comprising:
providing a dispenser having a rotatable and slideable eductor to control flow rate and chemical concentration;
rotating at least a portion of the eductor to select at least one of the flow rate and the chemical concentration to be dispensed into the stream of water;
sliding the eductor from a non-dispensing position to a dispensing position; and
engaging an interlock with the eductor while the eductor is in the dispensing position to prevent rotation of eductor.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
