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. (FIG. 1)
