Claim 6:
7. A hose nozzle for spraying fluids, the hose nozzle comprising:
a handle;
a body;
a nozzle head;
a fluid flow pathway extending through the handle, body and nozzle head, the nozzle head comprising:
a faceplate comprising a central pivot axis and an upstream faceplate face, the upstream faceplate face comprising an upstream sealing surface and defining two or more entry openings, wherein the faceplate is rotatable about the central pivot axis to two or more user-selectable rotational orientations, the two or more entry openings are disposed around the central pivot axis such that an intervening portion of the upstream sealing surface is disposed intermediate each of the two or more entry openings; and
a seal member defining a seal opening that comprises a portion of the fluid flow pathway, wherein the faceplate is rotatable to the two or more user-selectable rotational orientations such that the seal opening is in fluid communication with a selected entry opening and a corresponding user-selectable spray pattern pathway, the corresponding user-selectable spray pattern pathway comprising a portion of the fluid flow pathway;
the seal member having an arcuate shape,
the seal member comprising a first wing member and a second wing member extending away from the seal opening,
the seal member having a downstream seal face and an upstream seal face, the downstream seal face comprising a downstream sealing surface, wherein the seal member is devoid of indirect and direct contact with a spring such that no spring induces movement of the seal member; and
the downstream sealing surface being planar.
