    (54) Fluid control devices


    (57) A fluid control device comprising a pivotable member (8) which has a planar major face (22) and is mounted so as to enable pivotal motion about an axis (11) parallel to the major face. The pivotable member including a fluid jet channel (29) which directs a fluid jet towards a fluid receiving channel (37) defined in a receiving member (7).
    The pivotable member is pivotally rotated about the axis by means operable to pivot the pivotable member. This means may be an electromagnet (14) disposed with its poles (20,21) adjacent and parallel to the major face of the pivotable member.
    The motion of the pivotable member alters the relative positions of the fluid jet channel/channels and the fluid receiving channel/channels and thereby the quantity of fluid received by the fluid receiving channel/channels.
