Abstract (en)

A motor pump for high-pressure washers having a structure of the type that comprises a rotating plate (11) that is inclined with respect to its axis (13) and on which at least two pistons (15,16) push, the pistons (15,16) being arranged parallel to the axis (13) in radially spaced positions. The rotating plate (11) is associated for joint rotation with a motorized support (12), which is arranged opposite the pistons (15,16) and on which the plate (11) can oscillate freely in order to vary its inclination, with respect to the rotation axis (13), between preset values that determine the axial movement of the pistons (15,16), elastic elements (14) for contrasting the variations in inclination induced by the pistons (15,16) being functionally interposed between the plate (11) and the support (12). <IMAGE>
