Patent number: 4593729Abstract: A slide rack is pivotally supported at one end thereof on a plunger coaxially with an operating lever. On the other hand, a trigger which is urged in a direction away from the slide rack by a release spring has one end thereof pivotally supported on an intermediate portion of the operating lever, and the other end of the trigger is releasably engageable with a rack portion of the slide rack.For automatic shut-off fuel supply, the operating lever is pulled up and the fore end of the trigger is held in a rack portion of the slide rack to maintain a valve open position. As soon as a fuel tank is filled, the plunger is slided downward, whereupon one end of the slide rack is shifted downward with the other end slided along a lever guard. By this sliding movement, the trigger is released from the rack portion of the slide rack to return the operating lever automatically into a valve closing position.Type: GrantFiled: October 19, 1984Date of Patent: June 10, 1986Inventor: Shigenori Tamra

Patent number: 4559982Abstract: A pressure actuated poppet valve for a fuel dispensing nozzle is disclosed having a piston therein movable between a first and a second position. In the first position, the piston holds a plurality of coupling or latching balls in coupling engagement with an axially movable stem so that upon a user pulling the actuator handle or lever of the dispensing nozzle, the poppet valve is opened for the dispensing of fuel. When the dispenser goes off such that there is no fuel pressure in the hose upstream from the nozzle, a spring within the poppet valve pushes the piston from its first to its second position, thus permitting the coupling balls to move clear of the stem, allowing the poppet valve to close, and preventing opening of the poppet valve upon the subsequent actuating of the nozzle handle.Type: GrantFiled: December 27, 1983Date of Patent: December 24, 1985Assignee: Husky CorporationInventor: Arthur C.
