<p>A flow selectable fluid mixing device having a main manifold member (10) with a main fluid path (13) and a venturi creating conical secondary fluid path (14) and a rotatable manifold member (12) mounted on the main manifold member (10). The rotatable member (12) has valve gate means (19) which rotates within the main fluid path (13) of the main manifold member thereby controlling the fluid through that path. The rotatable member (12) also has an auxiliary fluid supply orifice (27) alignable with a venturi orifice (28) which is in fluid communication with the secondary conical fluid path (14) of the main member (10). The auxiliary fluid supply orifice (27) is in a fixed position with the valve gate means (19) such that three qualities of flow are selectable as the rotatable member (12) is rotated. </p> |
