- the second contact element 104 carries a marking 106 in the form of an arrow.
- the first contact element 102 forms a fixing element 108 in the form of a screw dome 110 forming a nut element.
- the screw dome 110 can be provided with a second fixing element 112 in the form of a screw 114 cooperate, which passes through the slot 88 from top to bottom clearance and with the screw dome 110 for fixing the second plate portion 78 on the support means 100 and thus the plate 74 on the flow channel 44 cooperates.

- the first abutment element 102 is fluted so that it has a recess 116 on its upper side facing the second plate section 78 (FIG. 4).
- the amount of combustion air supplied to the heat exchanger 36 can be adjusted by means of the plate 74 and in particular of the first plate section 76. Because the first plate portion 76 partially engages the channel interior 70 of the flow channel 44, it blocks a portion of the total, enclosed by the channel wall 58 cross-sectional area in the flow channel 44. For this reason, the combustion air passable free cross-sectional area of the flow channel 44 is smaller than the entire of the channel wall 58 bordered cross-sectional area. Therefore, the first plate portion 76 is also referred to as the channel narrowing portion 118.
- the plate 74 and thus the channel constriction section 118 can be displaced relative to the flow channel 44 in the displacement direction 82.
- the plate 74 is locked by means of cooperating with the screw dome 110 screw 114 on the second plate portion 78 and in particular on the slot 88.
- the second plate portion 78 forms, together with the screw 114 and the screw dome 110, a locking device 120 of the high-pressure cleaning device 10, and the second plate portion 78 is also referred to as a fixing portion 122.
- the screw 114 can be released relative to the screw dome 110. In this case, the user is facilitated access to the locking device 120 in that it is arranged outside the flow channel 44.
- the plate 74 can be moved relative to the flow channel 44. For example, this may be done by a user gripping the plate 74 by hand to move it. On the other hand, for example, it is possible for a user of a user-friendly setting device 124 to move the plate 74.
- the adjusting device 124 comprises the projections 96 which form adjusting elements 126.
- An adjusting tool that can be assigned to the plate 74 can be applied to them, and has an engagement surface that is complementary to the wave profile 94.
- a tool which is also suitable for loosening the screw 114 in particular a Torx screwdriver.
- the tool can be passed from the top through the slot 88, so that its lower end engages in the recess 116.
- its attack surface can roll on the wave profile 94.
- the adjusting elements 126 form a linear drive for the plate 74 with the tool.
- the plate 74 can thus be moved in the direction of the front side 12 or the rear side 13. Because the adjusting elements 126 are arranged on the second plate section 78, this is also referred to as the adjusting section 128.
- a guide device 130 When moving the plate 74 relative to the flow channel 44, it is guided by a guide device 130.
- the plate 74 is displaced in the direction of the front side 12, so that the free cross-sectional area of the flow channel 44 is reduced, only the heat exchanger 36, a smaller amount of combustion air is supplied. If the plate 74 is displaced in the direction of the rear side 13, the free cross-sectional area of the flow channel 44 is increased, and the amount of combustion air supplied to the heat exchanger 36 is increased.
- the formation of the actuator 72 as a slidable plate 74 is advantageous over the actuators of conventional high-pressure cleaning equipment, because due to the displacement of the plate 74 relative to the flow channel 44, the change in the free cross-sectional area has a linear dependence on the displacement of the plate 74 relative to the flow channel 44.
- the markers 98 on the second plate portion 78 and the mark 106 on the second abutment member 104 cooperate to form a display 134 by means of which the position of the plate 74 and thus the channel constriction portion 118 relative to the flow channel 44 can be displayed. On the basis of this display, the free cross-sectional area of the flow channel 44 can be determined.
- the plate 74 assumes the desired position relative to the flow channel 44, i. the free cross-sectional area of the flow channel 44 is adjusted by means of the channel constriction portion 118 such that the desired amount of combustion air is supplied to the heat exchanger 36, a user can fix the plate 74 by means of the locking device 120 again.
- the edge 90 of the elongated hole 88 forms a first stop element 136 at the end facing the front side 12, and a second stop element 138 at its end facing the rear side 13.
- the flow channel 44 is not completely blocked by means of the channel narrowing section 118. In this way it is ensured that the heat exchanger 36 is supplied in any case a minimum amount of combustion air.
- the channel constriction portion 118 still remains partially positioned in the channel interior 70. This ensures that the channel constriction portion 118 is not unintentionally passed through the slot 68 when displaced relative to the flow channel 44. In this way, an otherwise required re-insertion of the channel constriction portion 118 into the slot 68 can be avoided.
