1. A valve, comprising:
- a valve body connected to a spout and having an axial bore, a fluid inlet and a fluid outlet;
wherein the valve body is linked to a trigger assembly and connected to a flexible hose which in turn is connected to a hose take-up assembly, the hose take up assembly comprising a one-piece pulley having a groove and a housing for rotatably guiding the pulley, the hose being placed in a portion of the groove and the pulley being of sufficient weight to assist gravitationally in pulling the trigger assembly towards an end of the spout;
a chamber in the valve body which can be brought into fluid communication with the fluid inlet and outlet;
a slidable member positioned in the axial bore and the chamber, the slidable member having a fluid passage therein;
biasing means constructed and arranged in conjunction with the slidable member to bias the slidable member towards a first outward position, the slidable member being held at the first outward position by the biasing means in the absence of the opposing force;
wherein when the slidable member is in the first outward position, a first low flow can be produced through the valve, when the slidable member is in a second partially outward position a higher flow can be produced through the valve and when the slidable member is in a third, further inward position flow through the valve is stopped.

Abstract
A three position valve suitable for use in a trigger nozzle assembly is disclosed which is suitable for use in kitchen utensil rinsing areas has a valve housing with a bore, a fluid inlet and a fluid outlet. A biased slidable member is positioned in the bore and provides for fluid flow between the fluid inlet and outlet when the valve is in a first position. High flow and stop flow positions are also provided upon compression of the trigger. The valve can be employed in conjunction with a combined spray and aerator head, as well as a hose take-up assembly.
