摘要： The invention concerns a magnetic-bearing cell (1) of rotationally symmetrical construction which includes a rotor (2) with two permanent ring magnets (5, 6) and a stator (3) with a damping disc (27) projecting into the gap (26) between the permanent ring magnets (5, 6) of the rotor (2). In order to increase the radial rigidity of the cell, the invention proposes that an additional permanent ring magnet (7) is attached to the shaft (4), so that a gap (31) is formed between the additional magnet and the neighbouring magnet, and that a ring disc (32) attached to the stator (3) projects into this gap (31), the ring disc (32) carrying, in the vicinity of the rotating permanent ring magnets (6, 7) on the rotor (2), a longitudinally magnetized stator permanent ring magnet (33).

摘要： The invention relates to a rotationally symmetrical magnetic bearing cell (1) with a rotor (2) arranged to rotate about the central axis (10) of the cell (1) and having a shaft (4) and at least two axially magnetised permanent magnet rings (5, 6, 30) fitted an axial distance apart on the shaft, and with a stator (3) having pole components (12, 13, 16, 17) and two annular coils (14, 15) associated with the rotor end faces. To improve the radial rigidity without increasing active control complexity, it is proposed that pole components (26, 27, 38) of magnetically conductive material be provided for the peripheral regions of the two axially outer permanent magnet rings (5, 6 or 5, 30) to direct the magnetic flux generated by the annular coils (14, 15) into two substantially independent magnetic flux circuits (28, 29).

摘要： The invention concerns a lubricating process and a lubricating device for a vertical shaft bearing. In order to prevent insufficient lubrication whilst a machine is starting, an oil supply (8) is established in a first chamber (6) at a rotational speed of the shaft which corresponds to the normal running of the machine. The oil from this supply (8) flows into a further chamber (9) when the machine slows down. During a subsequent re-starting phase of the machine, before the feed mechanism in the oil feed duct (4) of the shaft (1) comes into action, the oil in the further chamber (9) is fed to the bearing (3) to be lubricated.

摘要： A fluid flow regulating valve has a control element made of an electrically heatable, shape memory alloy which adjusts a closure element against the restoring force of a spring according to a temperature-dependent longitudinal change in its position in relation to the valve seat. In order to keep constant a state of a fluid (for example pressure, flow rate, mixture composition etc.), the control element is a thread (1) heated by a constant current up to a temperature within the phase transition range of the shape memory alloy (SMA) and the valve body (20) which surrounds the thread (1) is designed as a heat exchanger which in co-operation with the thread reacts in a special way to changes in the state of a passing fluid flow. Appropriately, the valve body contains a bore (24) for receiving the SMA thread (1), for guiding the fluid flows to be regulated and for carrying out the heat exchange between the SMA thread (1) and the fluid flows, as well as channels (27) or joints (28).

摘要： The invention relates to a process for starting a machine fitted with a rotor on magnetic bearings and a circuit for implementing said process; in order to automate this process, the procedure is such that the fact that an axial stop bears on the rotor at rest and the correct position of the rotor when running -- its unstable equilibrium -- is about half a possible total travel of the rotor away from the momentary rotor stop position is used as information in order to apply electric power to the deflection coil in such a way that the rotor assumes its correct position virtually independently of the offset and that initially one of the two possible rotor stop positions is assumed to be given and an attempt is made to stabilise the rotor at about half of the possible total travel of the rotor from the assumed rotor stop position.
