This invention concerns a boiler fitted with a burner suitable for wall heaters or built-in kitchen heaters in which a mantle-shaped heat exchanger made of pipe elements connected in parallel and/or series divides the boiler chamber into a combustion chamber and an exhaust chamber. The heat exchanger has openings for hot flue gases distributed over its mantle. The burner head disposed in the combustion chamber is suitable for burning oil and has a flame tube with an axial flame opening and a flame baffle element disposed at a distance from the flame opening which is constructed so that the flame is diverted into the space between the flame tube and the heat exchanger. In addition, a fire chamber mantle can be disposed between the heat exchanger and the flame tube to protect the heat exchanger from direct contact with the flame.

The compressor according to claim 6 further comprising a hall effect magnetic sensor proximate to the rotor for detecting a change in polarity of the magnetic field of the rotor as a corner of the square cross-sectioned shaft rotates past the sensor. 8. The compressor according to claim 6 wherein the magnets are positioned on the shaft to define a continuous cylindrical surface. 9. The compressor according to claim 8 wherein edges of each magnet are positioned adjacent to the edges of magnets having opposite polarity. 10. The compressor according to claim 8 wherein edges of the magnets defined by the cylindrical surface thereof and the flat surface thereof abut the edges of magnets of opposite polarity. 11. A method of starting a multi-stage centrifugal compressor with an integral high-speed motor, wherein the motor has a stator and a rotor rotationally supported therein defining a gap therebetween and wherein the rotor is supported at each end by hydrodynamic oil bearings, wherein the method is comprised of the steps of: a) injecting pressurized air within the gap at a position between the ends of the rotor as the rotor begins to rotate to minimize the entry of oil from the bearings into the gap and b) when the rotor reaches a rotational speed sufficient to centrifugally expel oil outwardly from the rotor ends and away from the gap, discontinuing the injection of air. ric manner in relation to the housing, so that during operation each point on the displacement body executes a circular or elliptical movement, depending on a configuration of a guiding device, said movement being limited by cylinder walls of the feed chamber, and so that a curvature of the strips is dimensioned such that it almost touches inner cylinder walls and outer cylinder walls of the feed chamber on in each case at least one sealing line per strip, said sealing line advancing continuously during operation, and, in order to guide the displacement body in relation to the housing, an eccentric arrangement is provided which essentially consists of a drive shaft and of an eccentric disk arranged thereon, characterized in that one feed chamber is configured for compressing a working substance and the other opposite feed chamber for expanding said working substance, the feed chambers each have an inlet and an outlet, the inlet of any one feed chamber is separate from the outlet of the other opposite feed chamber, the feed chambers and the strips engaging in them consisting essentially of successive circular arc segments, radii of the circular arc segments in the compression-side feed chambers and strips essentially decreasing in size, when viewed in a direction of rotation, and radii of the circular arc segments in the expansion-side feed chambers and strips essentially increasing in size, when viewed in the same direction of rotation. 2.
