Definitions

  • the present invention relates to a pressure control device for a suction cleaner, comprising a valve provided on a suction tube and adapted to be opened to allow atmospheric air to flow into said suction tube.
  • Pressure controls of this kind are previously known which comprise a movable slide cooperating with an opening in the wall of the suction tube. By manual displacement of the slide the opening is uncovered in order to reduce the suction power as required.
  • the object of the present invention is to simplify the control of the pres­sure reduction valve in order to facilitate the cleaning operation.
  • the device illustrated in the drawings comprises a suction tube 10 con­nected to a partially shown suction hose 11 which in turn is to be connected to a suction cleaner (not shown).
  • the suction tube 10 is connected to a handle 12 which is formed as a pistol-butt.
  • a valve means 13 is provided which is made as a slide movable in the longitudinal direction of the suction tube and cooperating with an opening 14 in the tube wall.
  • the slide 13 is connected by means of a tension bar 15 to a control means 16 provided in the handle 12 and made as a trigger.
  • the control means 16 is provided with a catch mechanism 17 of a known type.
  • the valve is opened by squeezing the control means 16 against the action of the spring 18 whereby the device takes the position shown in Figure 2. In this position, the control means 16 is hitched by the catch mechanism 17 whereby vacuum cleaning can take place at a reduced suction power. When higher suction power is required, the control means 16 is squeezed again whereby the catch mechanism 17 is released and the valve returns to the closed position in Figure 1 as a consequence of the actuation by the spring 18.
