Abstract: The invention relates to a method of closing a bore (3) in a metal sintered component (2), whereby, prior to sintering a preform (1) to obtain the sintered component (2) or before a step of calibrating the sintered component (2), a closing body (5) is pushed into the bore (3), and the closing body (3) has an external diameter that is either of an identical size to or at least partially larger than the internal diameter (9) of the bore (3).

Abstract: A stator arrangement for an axial-flow machine includes a stator having stator teeth circumferentially distributed concentrically and axially separated from a rotor by an air gap. The stator teeth have two axially-opposite end portions and a tooth core therebetween. Each tooth core is wound with at least one coil winding. The first end portion facing the rotor forms a tooth tip having a tip cross-sectional area larger than the core cross-sectional area. The second end portion, turned away from the rotor, forms a tooth root, having a root cross-sectional area, which is joined to a reflux plate. The tooth tip of each stator tooth as well as the reflux plate respectively has at least one recess for at least one tooth securing device, and each stator tooth is securely joined by the at least one tooth securing device to the reflex plate in at least axial direction.

Abstract: A pump arrangement includes an axial-flow machine and a drive to convey fluid mounted in a housing. The axial-flow machine is formed by at least one first rotor having permanent magnets, a shaft connected to the first rotor and a stator arrangement with stator teeth distributed concentrically around the shaft axis circumferentially and axially separated from the first rotor by an air gap. The stator teeth have axially-opposite end portions and a tooth core therebetween wound with at least one coil winding. The second end portion, turned away from the first rotor, of each stator tooth forms a tooth root joined to a back plate. The first rotor is an eccentric disk and on the side away from the stator arrangement has an eccentric cam, radially spaced from the shaft axis, and rotatably and torque-transmittingly connected to the drive. An axial-flow machine and a compressor includes the pump arrangement.
