<p>1,080,672. Dispensing liquids. W. D. HENDERSON. Jan. 27, 1965 [Jan. 27, 1964], No. 3704/65. Heading A4T. An additive such as a colouring agent is injected into petrol delivered through a meter 2 operating a counter 10, the additive being supplied by a pump 22 to a push-pull four-way valve 23 operated by a solenoid 25 controlled by an impulser 76 operated from the shaft of counter 10 so that the additive is injected through a pipe 16 and nozzle 14 into the petrol at a rate determined by the flow through meter 2. A valve 3 allows petrol without additive to be dispensed and a counter 77 measures the quantity of petrol with additive. A metering device 33 with piston 34 determines the quantity of additive supplied at each throw of the piston of valve 23.</p> |
