Abstract (en)
[origin: WO2013053670A1] The invention relates to a piston pump for a high-pressure cleaning device, comprising several pistons (18) that can be moved back and forth. Said pistons each plunge into a respective pump chamber (52) and are movably retained on a piston guiding part (22). The piston guiding part (22) has a bearing wall (26) on which several guiding elements (24) are arranged, which guiding elements (24) each guide a respective piston (18). In order to be able to produce the piston pump more economically, the bearing wall (26) is curved.
