摘要： A variable geometry device is provided for use in a turbine engine having a support housing, a rotor contained within the support housing and a pair of spaced walls forming an annular and radially extending passageway open at one end to the rotor. An annular recessed channel is formed in one of the support housing walls while a ring is mounted within the channel and movable between a retracted position in which the ring is nested within the channel and an extended position in which the ring protrudes transversely into and variably restricts the passageway so that the restriction of the fluid passageway is substantially proportional to the transverse position of the ring. A plurality of circumferentially spaced vanes are secured to the ring and these vanes extend transversely across the fluid passageway and are slidably received within slots formed in the other support housing wall. In addition, the face of the ring open to the fluid passageway is contoured by meridional constriction for maximum engine efficiency.

摘要： An apparatus for improving the efficiency of a turbo-supercharger at low load levels is disclosed. The apparatus includes an annular gas inlet housing which encircles the turbine of the turbo-supercharger and which housing includes an inlet for gases flowing toward the turbine. Arranged within the housing is a diaphragm, an outer periphery of which diaphragm is connected to the housing. Connected to the inner periphery of the diaphragm is a guide vane ring. Biasing springs, arranged within the housing, urge the diaphragm, and thus the guide vane ring connected to the diaphragm, toward the inlet.

摘要： 1,029,647. Turbines; centrifugal compressors. SULZER BROS. Ltd. April 6, 1965 [May 11, 1964], No. 14585/65. Headings F1C and F1T. A radial flow compressor or turbine has a diffuser the axial spacing between the walls 1, 2 of which is adjustable, a ring of stator vanes 5 on wall 1 extending into an annular recess in wall 2, filling elements 6 in the recess shaped to correspond approximately to the flow passages 3 between the vanes and relative to which the vanes slide when the spacing between the walls is adjusted, and sealing members 9 of selflubricating plastic material, such as polytetrafluoroethylene, forming seals between the vanes 5 and the filling elements 6. The sealing members 9 are pressed against the vanes 5 by rubber members 13, members 9, 13 being retained in position by T-pieces 11. Sealing members 9 are also provided between vanes 5 and the outer periphery of the annular recess, Fig. 4 (not shown). Vanes 5 and elements 6 are attached to walls 1, 2 by screws 7, 8 respectively, wall 1 being fixed and wall 2 movable.

摘要： 881,882. Centrifugal pumps and compressors. SULZER FRERES S.A. Dec. 8, 1958 [Dec. 23, 1957], No. 39514/58. Class 110 (1). A centrifugal pump or compressor comprises a first ring 4 concentric with the rotor shaft and forming a part of one of the walls of the diffuser of the pump or compressor, the flow cross-section of the diffuser being adjustable by varying the distance S between the diffuser walls by axial movement of the first ring 4, a second ring 13 concentric with but axially spaced from the ring 4 and restrained from axial movement, and at least three motiontransmitting members 12 extending between the two rings and arranged at the same angle of akew α in relation to the rotorshaft, the rings 4, 13 being relatively rotatable and the members 12 being arranged to convert relative rotation of the rings into axial movement of the first ring 4. As shown, the ring 4 is held against push members 11 and the members 12 by a spring 10 and the excess of the pressure between the diffuser walls over that behind the ring 4. Each motion-transmitting member 12 has two spherical ends, one located in a guide passage 14, and the other in a recess 16 in the ring 13. A space 19 containing the motion-transmitting members 12 is sealed off from the diffuser by metal bellows or other sealing members 20 and the first ring 4 has a sealing ring 7. The second ring 13 is rotated by a worm 17 engaging a toothed segment 18 and rotation of the ring will displace the members 12 as in the upper diagram of Fig. 2, which shows the mechanism with the skew angle α at a maximum. The arrangement described compensates for the increasing percentage reduction in flow cross-section for a given movement of the ring 4 as the distance between the walls decreases. An adjusting screw 22 may be provided for adjusting the effective length of the member 12.
