Abstract: A high-pressure cleaning appliance is provided, including a heatable heat exchanger for heating a fluid that can be dispensed by the high-pressure cleaning appliance, a motor having a drive shaft that defines a drive axis, a pump unit, a fan for generating a combustion air stream and having a fan housing, and a fuel pump. The high-pressure cleaning appliance includes a first securing device having at least one securing element and a securing element receptacle integrally formed on the fan housing and associated with the at least one securing element, and the first securing device can be transferred from an unsecured position, in which the fuel pump can be coupled to the drive shaft and released from it, to a secured position by inserting the at least one securing element into the securing element receptacle to prevent the fuel pump from being released from the drive shaft.

Abstract: In a closure device for the fluid delivery line of a high-pressure cleaning apparatus having arranged in the fluid delivery line a closure member which is pressed with a closing force against a valve seat and thereby closes the fluid delivery line, and which is liftable off the valve seat by a mechanical actuating element displaceable by a hand lever and extending in a sealed manner out of the fluid delivery line, when the hand lever is moved in the direction of an open position, in order to reduce the holding forces when the hand spray gun is open, it is proposed that downstream of the valve seat in the fluid delivery line a displaceably mounted piston extend in a sealed manner out of the fluid delivery line and upon being pushed out of the fluid delivery line cooperate with the hand lever in such a manner that the hand lever is moved in the direction towards its open position.

Abstract: A holding device for sealed insertion of cables (18) through enclosure walls, having a holding plate with several cable lead-through openings (13), which can be mounted on the enclosure wall also having cable lead-through openings, and an elastic sealing plate (11), which in the mounted state is located between the holding plate (10) and the enclosure wall. The sealing plate (11) has pre-manufactured cable perforation points (14) in true alignment with the cable lead-through openings (13). Furthermore, the holding plate has flexible holding tabs (15) extending sideways into the cable lead-through openings (13), and each of the tabs is deflected toward the enclosure wall if a cable (18) is inserted into the appropriate cable opening (13) and, if tensile strain is placed upon the cable (18), digs into the cable in the opposite direction, whereby the deflection toward the wall remains.
