Title (DE) KOLBENPUMPE FÜR EIN HOCHDRUCKREINIGUNGSGERÄT
(EN) PISTON PUMP FOR A HIGH-PRESSURE CLEANING DEVICE
(FR) POMPE À PISTONS POUR APPAREIL DE NETTOYAGE HAUTE PRESSION
Abstract: front page image
(DE)Kolbenpumpe für Hochdruckreinigungsgerät mit mehreren hin und her bewegbaren Kolben (18), die jeweils in einen Pumpraum (52) eintauchen und an einem Kolbenführungsteil (22) verschiebbar gehalten sind. Das Kolbenführungsteil (22) weist eine Tragwand (26) auf, an der mehrere Führungselemente (24) angeordnet sind, die jeweils einen Kolben (18) führen. Um die Kolbenpumpe kostengünstiger herstellen zu können, wird die Tragwand (26) gewölbt ausgeführt.
(EN)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.
(FR)Pompe à pistons pour appareil de nettoyage haute pression, comportant plusieurs pistons (18) à mouvement alternatif, chacun plongeant dans une chambre de pompe (52) et étant maintenu coulissant sur un élément de guidage de piston (22). L'élément de guidage de piston (22) comprend une paroi portante (26) sur laquelle sont disposés plusieurs éléments de guidage (24) qui guident chacun un piston (18). L'invention vise à rendre la production de la pompe à pistons plus économique. A cet effet, la paroi portante (26) est cintrée.
