Abstract: An internal rotor for an electric motor has a laminated rotor core with a multiplicity of rotor plates, and multiple pockets in each of which pocket a rotor magnet is at least partially arranged. The rotor plates have first recesses for forming the pockets and at least a first rotor plate which has at least a second recess associated with a first recess. A sprung web-shaped clamping element is formed between the second recess and the associated first recess, and tensioned toward the second recess by the associated rotor magnet to apply a force to the associated rotor magnet toward the first recess in order to hold the associated rotor magnet in the pocket. A rotor plate holds a rotor magnet in a pocket of a laminated rotor core.

Abstract: The invention relates to a pump device for pumping a liquid, comprising a hydraulics housing (12, 212), in which a pump ring (14, 214), a pump ring support (16, 216) and an eccentric (18), which can be driven by a shaft (20), are accommodated. The hydraulics housing (12, 212) has an annular portion (22, 222) and a first and a second lateral section (24, 26, 224), the two lateral sections (24, 26,224) being arranged opposite each other. The pump ring (14, 214) is mounted between the two lateral sections (24, 26, 224) of the hydraulics housing (12, 212) at least in some portions. On a side facing away from the pump ring support (16, 216), two first projections (28, 228), which run in the axial direction of the shaft (20), are each in contact with one of the two lateral sections (24, 26, 224).
