| 20090324391 | Rotary separator and shaft coupler for compressors - A separator is for a turbomachine, preferably a compressor including a casing, a primary compressor shaft with an impeller disposed within the casing, and a drive shaft connectable with the compressor shaft. The separator includes a coupler having a central axis and being configured to connect the drive shaft with the compressor shaft such that the rotation of the driver shaft rotates the coupler and connected compressor shaft. A separation surface extends circumferentially about the axis so as to at least partially define a flow passage for a fluid stream, the separation surface being disposed either generally within or generally about the coupler. The separation surface is connected with the coupler such that rotation of at least one of the two shafts rotates the separation surface generally about the axis so that liquid within the fluid stream contacting the separation surface is separated from the fluid stream. | 12-31-2009 |
| 20090322033 | Shaft isolation seal - A seal assembly is for a compressor including a casing having first and second chambers and a shaft extending through the casing between the two chambers. The seal assembly includes a main body disposed about the shaft and between the two chambers and having a central axis, an inner surface spaced radially outwardly from the shaft to form a seal chamber. Annular sealing members are connected with the main body and extend radially from the body inner surface toward the shaft, the sealing members preventing flow between the first and second chambers through the seal chamber. A separator is coupled with the shaft adjacent to the main body and has separation passages fluidly connecting one of the two chambers with the seal chamber, each passage extending radially with respect to the shaft axis so as to direct liquids and solids contacting the passage inner surface away from the seal chamber. | 12-31-2009 |
| 20090321343 | Dual body drum for rotary separators - A drum is for a rotary separator including a shaft rotatable about a central axis. The drum includes an inner drum member having inner and outer circumferential surfaces and being disposed generally about the shaft such that a first flow passage is generally defined between the inner drum member inner surface and the shaft. The inner drum inner surface is configured to separate liquids from a fluid flow contacting the surface. An outer drum member has inner and outer circumferential surfaces and is disposed generally about the inner drum member such that a second flow passage is generally defined between the outer drum member inner surface and the inner drum member outer surface, the second flow passage being generally coaxial with the first flow passage. Further, the outer drum inner surface is also configured to separate liquids from a fluid flow contacting the surface. | 12-31-2009 |
| 20090304496 | ROTARY SEPARATOR DRUM SEAL - A seal assembly for a compressor includes a static member fixedly disposed within a compressor casing and having an end surface and a rotatable separator coupled with a compressor shaft and spaced from the static member. The separator has an axial end with a radial end surface located adjacent to the static member end surface such that a clearance space is defined therebetween. The separator has a plurality of openings extending inwardly from the end surface and spaced about the shaft axis such that land surface sections are defined on the end surface. The land surface sections or/and the openings are configured to prevent fluid flow radially inwardly through the clearance space. The static member has two annular walls receiving an end portion of the separator, with annular ridges providing labyrinth seals disposed against inner and outer surfaces of the separator, and an annular deflector with an angled deflector surface. | 12-10-2009 |
| 20090238699 | CONTROL VALVE ASSEMBLY FOR A COMPRESSOR UNLOADER - A closing element is for a valve assembly of a compressor unloader, the compressor including a casing with a compression chamber, the unloader including a housing defining a chamber. The valve assembly has a base between the compression and unloader chambers, a passage connecting the two chambers, a seat about the passage, and a stem bore within the base having a control chamber. The closing element includes a main body movably disposed within the stem bore and having a sealing surface disposeable against the valve seating surface to obstruct the valve passage and a control end surface within the bore control chamber A sealing member disposed about the main body prevents flow between the control chamber and the valve passage. The main body and/or the sealing member is configured such that the main body is radially moveable to align the body sealing surface with the valve seat. | 09-24-2009 |
