Abstract: An indicator device is for sensing a valve of a fluid machine including a casing having an interior chamber, a valve controlling flow into the interior chamber, and a rotatable shaft configured to displace the valve between open and closed positions when the shaft moves between first and second angular positions. A first indicator member, preferably a pinion gear, is coupled with the shaft such that angular movement of the shaft angularly displaces the first member. A second indicator member, preferably a rack gear, is coupled with the first member such that the angular displacement of the first member linearly displaces the second member. The second member linear displacement is generally proportional to angular displacement of the first member. Further, a sensor is configured to sense at least one of linear displacement and linear position of the second indicator member so as to sense the position of the valve.

Abstract: A fluid processing machine processes multiphase fluid streams including gas and liquid. A housing has an interior chamber, an inlet fluidly connected with the interior chamber and with a stream source, and first and second outlets. A separator disposed within the housing chamber is fluidly coupled with the inlet such that the stream flows thereto and separates the stream into gaseous and liquid portions. A compressor disposed within the chamber receives and compresses the gaseous portions from the separator for discharge through the housing first outlet, the compressor having an outer surface spaced from the housing inner surface to define a flow passage. A pump disposed within the chamber has an inlet fluidly coupled with the separator through the passage, is spaced vertically from the separator so that liquid flows by gravity from the separator to the pump, and pressurizes the liquid for discharge through the housing second outlet.

Abstract: A high pressure turbomachine includes a casing having an interior chamber and a generally annular wall section defining an opening into the interior chamber and having an outer circumferential surface. A closure device is engageable with the casing and includes a body having an inner circumferential overlap surface defining an opening. The closure body is configured to receive at least a portion of the casing annular wall section within the body opening such that the closure body overlap surface extends about the annular wall section outer surface to substantially close the casing opening. When the casing chamber contains high pressure fluid, the casing wall section expands radially outwardly such that the casing section outer surface pushes generally radially outwardly against the closure body overlap surface, the closure body being configured to either minimize or substantially prevent casing wall radial expansion.

Abstract: A control system is provided for load sharing between a plurality of compressors (8, 34). The control system determines the actual coefficients of export flow for the compressors (CEF actual1 , CEF actual2 ), compares the actual coefficients of export flow with a common or individual coefficients of export flow setpoints (CEF SP) generated by one or more central controllers (48, 50), and then generates control signals for adjusting the operating points of the compressors in order to load balance the compressors.

Abstract: A damper film bearing assembly (10) for supporting a rotatable shaft (11) of a turbomachine includes a housing (22) having a central bore sized to receive the bearing member, and an annular cavity (34) formed within the housing around the central bore. The annular cavity (34) includes an outer wall (36) that is concentric with the central bore. A bearing member (35) having an annular outer surface and an inner bearing surface is mounted within the cavity and engages the shaft (11) to support the shaft within the housing. A fluid film damper mechanism (55) acts between the annular outer surface (39) and the outer wall of the cavity (36) for damping radial movement of the bearing member within the cavity. A resiliently adjustable dead weight hanging spring support system (61, 62) acts between the housing and the bearing member to support the dead weight of the shaft within a vertically centered position within the central bore so that the fluid film damper means functions to maintain the shaft centered within the bore when vibrations occur during rotation of the shaft.

Abstract: A compressor piston (154) divides a first compartment (153) into two compression chambers (155, 156), while a hammer piston (285) divides a second compartment (284) into two drive chambers (286, 287), each of the compression chambers (155, 156) being connected to a respective one of the drive chambers (286, 287) to form a closed fluid system wherein reciprocation of the compressor piston (154) causes cyclic compression and expansion of the fluid in the compression chambers (155, 156) and thus in the drive chambers (286, 287), to effect a cyclic impacting of the hammer piston (285) with a bit adapter (27) connected to the drill bit (14). A mud motor (16) rotates a shaft (68) to drive an oscillator (172) which reciprocates the compressor piston (154). The oscillator (172) can comprise roller elements (191-198) in the compressor piston (154) in engagement with canted grooves (181-184) in the shaft (68).

Abstract: A bearing and/or seal assembly (10) where pressurized gas (e.g., air) may be arranged to produce a contact-free bearing and/or seal is provided. The assembly includes a permeable body (12) including structural features (13) selectively engineered to convey a pressurized gas (Ps) from an inlet side (20) side of the permeable body to an outlet side (22) of the permeable body to form an annular film of the pressurized gas relative to the rotatable shaft. Disclosed embodiments may be produced by way of three-dimensional (3D) Printing/Additive Manufacturing (AM) technologies with practically no manufacturing variability; and may also cost-effectively and reliably benefit from the relatively complex geometries and the features and/or conduits that may be involved to, for example, form the desired distribution pattern or impart a desired directionality to the pressurized gas conveyed through the permeable body of the bearing and/or seal assembly.
