Abstract: A fuel-injection valve comprises an electromagnetically actuated armature attached to the needle-like stem of a valve head. In order to promote control of fuel flow under varying conditions the valve opens by moving the valve head downstream from its valve seat and the stroke of the valve head is limited by a mechanical stop situated downstream of the valve seat.

Abstract: A dishwashing machine including upper and lower dish supporting racks and a liquid wash spray assembly having a rotating arm for spraying water upwardly on the lower dish load and an extendable top wash tube which sprays liquid at an intermediate level between the upper and lower dish supporting racks in the machine. A liquid diverting system provides means for automatically alternating the flow of water between the rotating spray arm and the extendable top spray tower. Water is directed continuously to a jet port on the spray arm which insures that the arm will continue to rotate independent of the liquid diverting system when the water is diverted to the top spray tower. The spray arm and tower each deliver effective water flow on an alternating basis while the overall flow rate and the total water consumption is reduced.
