摘要： A fluid machine (16) in communication with a thrust bearing fluid source (410) includes a housing (110) having a bearing portion (420) receiving fluid from the fluid source. A bearing chamber (422) is formed in the bearing portion (420). An extension (452) of a rotor (450) is positioned within the bearing chamber (422) so that a first pocket (460) is disposed adjacent to a first side (454) of the extension (452) and a second pocket (464) is disposed adjacent to a second side (456) of the extension. An extension lateral side (458) is adjacent to the bearing chamber lateral side (430). The extension (452) comprises a first channel (482) extending from a first half (481) of the extension lateral side to the first pocket (460). The extension (452) comprises a second channel (482') extending from a second half (481') of the extension lateral side opposite the first channel (482) to the second pocket (464). The bearing chamber (422) receives fluid from the bearing channel (431) which is communicated to the first (482) and second (482') channels and the pockets (460, 464).

摘要： A turbine and method of operating a turbine includes a housing (202) having an inlet (24), a volute (232) and an outlet (30). The inlet (24) is coupled to the volute (232) through a primary fluid path (240) and a secondary fluid path (242). The turbine further includes an impeller (228) rotatably coupled to the housing (202) and a hydraulically actuated valve assembly (204) disposed within the secondary fluid path (242) selectively communicating fluid from the inlet (24) to the volute. The turbine includes a hydraulic actuator coupled to the valve assembly (204) moving the valve assembly (204) from a first position communicating fluid from the inlet into the volute to a second position blocking flow from the inlet to the volute.

摘要： A throttle housing (12) having an inlet end (14) and an outlet end (16) includes a shuttle housing (30) disposed within the throttle housing (12). The shuttle housing (30) has a first end cap (36) at a first end (32) and an orifice array (38) therethrough. The shuttle housing (30) comprises a shuttle housing therein. The shuttle (40) has an opened position and a closed position relative to the shuttle housing (30). The shuttle (40) defines a varying control volume (50) between the end cap (36), the shuttle (40) and the shuttle housing (30). The control inlet (62) fluidically communicates a control fluid to the control volume (50) to control the position of the shuttle (40) in the shuttle housing (30).
