Definitions

  • both of the liquid supply passage means 28 and 36 in the delivery means 8 are arranged to jet liquid to their respective edged portions, the edged portions 26 a and 26 c respectively, in the embodi­ment shown in Fig. 6.
  • the liquid supply passage means 28 and 36 to jet liquid to these edges may be inclined at an angle ⁇ in the range of 10° to 60°, for example, the liquid supply passage means 28 and 36 intersecting and opening into the outer end face 8 a of the liquid delivery means 8.
  • the injection angles ⁇ of the supply passage means 28 and 36 with respect to the selected edged portions 26 a to 26 d may be selected to be either the same or different from each other.
  • edged portions 26 a to 26 e of the vibrating element 10 are shown as concentric V-shaped ridges having the same diameter in the illustrated embodiments so far described, they may be in the form of two or more annular steps having progressively decreasing or increasing diameters, or progressively decreasing and then progressively increasing diameters. What is important is that liquid be applied separately at two or more different edged portions (including the vicinity of the edges of the edged portions), regard­less of what configuration of edged portion of vibrating element may be employed.
