    Abstract: A FLUID INJECTION SYSTEM COMPRISING A TUBULAR MEMBER (12), A VENTURI (14), FIRST AND SECOND VOLUMES ARRANGED TO CONTAIN FIRST AND SECOND FLUIDS RESPECTIVELY. THE VOLUMES BEING SEPARATED BY A BLADDER (30), THE TUBULAR MEMBER (12) ON A HIGH PRESSURE SIDE OF THE VENTURI (14) BEING IN FLUID COMMUNICATION WITH SAID FIRST VOLUME AND A METERING LINE (40) EXTENDING FROM THE TUBULAR MEMBER ON A LOW PRESSURE SIDE OF THE VENTURI AND BEING IN FLUID COMMUNICATION WITH SAID SECOND VOLUME. IN USE A PRESSURE DIFFERENTIAL IS CREATED ACROSS THE VENTURI (14) SO THAT THE FIRST VOLUME IS INCREASED BY FLUID PASSING FROM THE FLUID LINE (12) INTO THE FIRST VOLUME AND BY MOVEMENT OF THE BLADDER THE SECOND VOLUME IS CORRESPONDINGLY DECREASED BY FLUID PASSING THEREFROM WHEREIN BYPASS CONDUIT MEANS (50) IS PROVIDED.

    Abstract: The present invention relates to a fluid injection system comprising a tubular member (12) arranged to form part of a fluid line through which, in use, fluid flows under pressure, a venturi (14) contained within the tubular member (12), first and second volumes arranged to contain first and second fluids respectively, said first and second volumes being separated by a pressure responsive means such as a bladder (30), the tubular member (12) on a high pressure side of the venturi (14) being in fluid communication with said first volume, and a metering line (40) extending from the tubular member on a low pressure side of the venturi and being in fluid communication with said second volume, the arrangement being such that, in use a pressure differential is created across the venturi (14) so that the first volume is increased by fluid passing from the fluid line (12) into the first volume and by movement of the pressure responsive means, the second volume is correspondingly decreased by fluid passing therefrom through the conduit into the fluid flowing through the fluid line, wherein bypass conduit means (50) is provided between the high pressure side of the venturi and the line (12) on the low pressure side of the venturi (14) so as to provide an alternate flow of fluid in the line and modify through volumetric displacement the rate of flow of the second fluid.
