In a compressor, in particular for exhaust gas turbochargers, the compressor housing rear wall of the compressor housing enclosing the compressor wheel is mounted on a stator housing for mounting the drive shaft. The compressor housing rear wall is divided into a central disk and at least one outer ring, at least one vibration-damping and structure-borne sound-damping separating ring surrounding the central disk peripherally connecting the two adjoining housing wall portions together. Between the separating ring and the housing wall portions one or two metal bushings are inserted in which the housing wall is held frictionally and/or in form-locking manner.

The invention relates to turbine wheels and in particular an improved way to form the connection between non-metallic turbine wheels and a metallic shaft. The resulting structure provides a secure connection therebetween, reduces tension loads otherwise placed on the non-metallic turbine wheel allowing higher rotational speeds and provides bearing and sealing areas.

Improved connection structure for joining ceramic and metallic parts of

Disclosed are means and method for forming elastic connection between ceramic and metallic structural elements. The means comprises a ceramic structural element; a metallic structural element having thermal and elastic properties different from those of the ceramic structural element; and a connecting element connecting the ceramic and metallic structural elements and comprising an insulating resilient body of ceramic material having a thermal conductivity of between about 0.02 and 0.25 W/cmK at a temperature difference between the ceramic and metallic structural elements of from about 100 to 1500 Centigrade degrees, an elastic modulus of between about 5000 and 150,000 N/mm.sup.2 and being substantially free of plastic deformation.

Element and method for connecting ceramic and metallic parts

An operative member for a quick shut-off apparatus for steam turbines formed of a non-arcing solid material having a predetermined characteristic value determined by the breaking elongation, breaking stress, modulus of elasticity and specific weight, such as an extruded polyamide.

Operative members for use in a quick shut-off apparatus

Advance diffuser for an axial blower having an impeller of large diameter received in a substantially circular housing and an axis extending in a given direction, includes a suction box formed with an intake opening through which a medium is drawable by suction in a direction substantially perpendicular to the given direction of the blower axis, a plurality of swirl vanes mounted on respective, mutually parallel shafts in the suction box, the suction box having a pair of mutually opposing parallel walls wherein the shafts are rotatably mounted, a pair of casing surface sections mutually connecting the parallel walls and tangentially merging with and surrounding the substantially circular outline of the impeller housing, the suction box having another wall facing toward the impeller and formed with a suction opening, the parallel shafts whereon the swirl vanes are respectively mounted being disposed along an arc surrounding part of the suction opening, the arc having end points mutually connectible by a secant to the circular outline of the impeller housing.
