Definitions

  • the invention relates to a hand-held spray gun for a high-pressure cleaning device with a feed line for a cleaning medium under high pressure and with an outlet opening which is connected to the feed line via a throttle point with a variably adjustable cross-section, an actuating element for changing the cross-section of the throttle point and above on the hand-held spray gun the outlet opening is arranged a display which indicates the position of the actuating element relative to the hand spray gun and wherein the actuating element is a sleeve surrounding the outlet opening and rotatable about its longitudinal axis.
  • This object is achieved in that an actuating element for changing the cross section of the throttle point and a display are arranged on the hand spray gun, which indicates the position of the actuating element relative to the hand spray gun.
  • the change in position of the actuating element is therefore used to make a display on the hand spray gun itself, on which the operator can read the respective throttling effect.
  • This throttling effect is a measure of the amount of liquid dispensed on the one hand and a measure of the temperature of the dispensed liquid on the other hand, so that the user can be given information about both the amount of dispensed liquid and its temperature by means of a corresponding double scale. No complicated measuring devices are necessary for this, but an appropriate display can be made solely by the respective position of the actuating element.
  • the display on the hand spray gun is arranged above the outlet opening, since the operator can see such an display particularly well in this area.
  • the actuating element is a sleeve surrounding the outlet opening and rotatable about its longitudinal axis.
  • the sleeve carries a transparent window through which a part of the hand spray gun receiving the outlet opening is visible. It can be, for example, a flow channel through which the cleaning liquid flows.
  • the hand spray gun has a transparent window through which the sleeve is visible.
  • the window and the scales or marking elements interacting through this visible part carry the operator with the desired information about the quantity dispensed and the temperature. It is particularly advantageous if two scales are provided, namely a scale for the quantity dispensed and a scale for the temperature, so that the operator can simultaneously read these different values, which are influenced in the same way by the position of the actuating element.
  • a slide is arranged displaceably along the bore, which narrows the flow channel to different degrees in different positions in the bore and by means of the actuating element is displaceable in the bore.
  • the actuating element is a sleeve, it is advantageous if it carries a slideway which is eccentric to its axis of rotation and on which the slide rests. In this way, a structurally particularly simple, non-bulky and nevertheless easily operable setting for the throttle in the hand-held spray gun is obtained, which at the same time enables the desired display of the values achieved by the setting.
  • the hand-held spray gun 1 which is only partially shown in the drawing, comprises a handle part 2 and a housing 3 in which there are flow fittings.
  • a supply line for a cleaning medium in the form of a flexible high-pressure hose opens into the handle part 2, this is not shown in the drawing. It leads to a flow channel 4, which is arranged in the interior of the housing 3 and ends in a step-widening manner in an outlet opening 5, onto which, for example, a spray lance (not shown in the drawing) can be screwed.
  • a sleeve 6 is arranged on the flow channel 4 so as to be rotatable about its longitudinal axis. It carries on its inside a slide 7 which is eccentric to its axis of rotation and against which a slide 8 bears on both sides (FIG. 3) and which seals it in a bore 9 passing through it in a direction transverse to the longitudinal direction of the flow channel 4 and is mounted for longitudinal displacement.
  • the slide 8 passes through the flow channel 4
  • the latter has a part 10 completely filling the bore 9 and an adjoining circumferential groove 11, ie in the region of the circumferential groove 11 there is between the slide 8 and the inner wall of the bore 9 an annular space 12 surrounding the slide 8.
  • the flow channel 4 can be completely blocked, namely when the part 10 of the slide 8 with a large diameter is inserted into the flow channel 4.
  • a complete opening of the flow channel 4 is obtained, however, when the area of the annular space 12 is inserted into the flow channel 4, with intermediate positions of the slide 8, there is a stepless cross-sectional narrowing of the flow channel 4 between these two extreme values.
  • the slide 8 is displaced simply by rotating the sleeve 6 and the eccentric slideway 7 connected to it.
  • the front end 13 of the sleeve 6 engages under a cylindrical cap 14, which is rotatably mounted on the flow channel 4 and has a rectangular recess 15 in its top, in which a transparent window 16 is located.
  • the front part of the sleeve 13 arranged below the cap 14 can be seen through this window 16; the sleeve 13 carries in this area a marking element 17, which is recorded on the outside of the sleeve in a helical manner and concentric to the axis of rotation of the sleeve 13 and which passes through the window 16 is visible through it and, when the sleeve 6 is rotated relative to the flow channel 4, shifts in the central region of the window 16 in the longitudinal direction of the flow channel 4.
  • Scales 18, 19 are recorded on the window 16 on both sides of the center, between which a transparent area 20 remains, through which the marking element 17 can be seen.
  • the two scales are arranged in opposite directions, one scale indicates the amount of liquid dispensed, the other the temperature, both sizes are opposite. This enables the operator to read directly on the two scales how large the amount of liquid currently dispensed is and what temperature it is. These values can be adjusted in a precisely observable manner simply by turning the sleeve.
