Abstract
In order for a high-pressure cleaner having a reciprocating pump, on which there is positioned a pump head into which at least one piston, which can be moved back and forth in the longitudinal direction of the reciprocating pump, projects, the pump head comprising a suction connection, for feeding a cleaning liquid, and a pressure connection, for discharging the cleaning liquid, accommodating a plurality of regulating valves, being produced from plastics and being braced with the reciprocating pump by means of a clamping element, to be developed such that it can be produced more cost-effectively and assembled more straightforwardly, it is proposed that the clamping element has at least one U-shaped clamping bracket with a base part butting against the pump head and with two legs which are aligned substantially in the longitudinal direction of the reciprocating pump and the free ends of which butt against an abutment surface, produced from metal, of a piston guide of the reciprocating pump and can be connected releasably to the reciprocating pump.
