Abstract: 1,215,115. Resetting counters. LJUNGMANS VERKSTADER AB. 3 June, 1969 [10 June, 1968], No. 28011/69. Heading G4D. At the beginning of a self-service fueldispersing operation the application of fluidpressure to a control valve causing resetting of the register before fuel is delivered. The control valve comprises a spool-type slide 15 in a cylinder 14. The first application of fluid-pressure passes fluid through a part (34, Fig. 3, not shown) to the underside of a piston 11 which lifts a rack 4 to rotate the spindle 1 of the usual register through a oneway drive, so zeroizing the register. At the same time a plate 20 is swung to the left so that piston 15 can rise to engage pin 18 with abutment 35. Further parts are then rendered effective so that piston 11 is driven down to original position, at which time plate 20 is rocked further to the left. Piston 15 is then free to rise to its uppermost position in which pressure fluid passes through a part (41, Fig. 5, not shown) to the dispensing nozzle, driving the register in known manner. When dispensing ceases the drop in fluid pressure allows the piston 15 to fall under the action of spring 42 and plate 20 resumes original locking position.
