ABSTRACT:
A fluid flow regulator 10 comprises a body 11 defining three converging flow passages A, B and C between inlets 14, 13 and 12 respectively, and outlet 15, which is connectable to a suction source. Passages A and B each includes a valve. Turbine 16 in passage C drives actuating means periodically to operate the valves thereby to cause passages A and B periodically to be opened and closed in tandem. The regulator may be employed to suck predetermined quantities of fluid from two sources connected to inlets 14 and 13, respectively. Another embodiment serves as displacement apparatus for a submersible cleaner. With passage B open to admit water to drive a propeller 34 for displacing the apparatus and cleaner, passage A is closed to reduce suction at the cleaner. With passage B closed, passage A is open to transmit suction to the cleaner for it to be propelled by its own driving mechanism.
