Latest Patents

Among his latest patents is a flow rate limiting device for an automatic shut-off liquid dispensing system. This invention features an automatic shut-off dual dispensing nozzle equipped with a flow rate limiting mechanism. The nozzle includes a valve that controls the flow of fuel through a passage leading from the nozzle inlet to the nozzle outlet, which is typically connected to a spout. This valve is responsive to a manually operable lever and a vacuum-operated release mechanism, which automatically shuts off the flow of fuel when the fuel level in a tank reaches a preselected level or when the flow rate exceeds a predetermined threshold.

Another significant patent is for a fuel dispensing nozzle designed for gasoline fuel pumping stations. This nozzle has an inlet for fuel supplied within a range of inlet pressures and an outlet for discharging fuel. The flow passage includes valving that selectively opens communication between the inlet and outlet based on the pressure differential across the valving. The valve member is actuated to control the flow, ensuring that the maximum predetermined flow rate is not exceeded.
