Variable displacement turbocharger and assembly method of variable nozzle mechanism
It is provided with: a variable nozzle mechanism for regulating a flow of exhaust gas to a turbine rotor; a link mechanism for converting reciprocal displacement from an actuator that operates a variable nozzle mechanism into rotational displacement and transmitting the rotational displacement to an inner section of a bearing housing; and an engaging part for engaging an output section of the link mechanism and an input section of the variable nozzle mechanism, and the engaging part is constituted by a pin and a pin insertion slot where the pin is inserted, and a smooth surface is formed around an insertion position of the pin so as to guide a tip of the pin to the insertion position.
Bundle guiding device of compressor and bundle guiding method of compressor
A bundle guiding device includes an inner roller mounted on a front portion of a bundle in an insertion direction where the bundle is to be inserted into a casing and configured to roll on an inner peripheral surface of the casing, an outer roller mounted on a rear portion of the bundle in the insertion direction where the bundle is to be inserted into the casing and configured to travel on a rail member, and a position adjusting mechanism configured to adjust a position of the bundle in a horizontal direction orthogonal to the insertion direction by applying an adjusting force to a receiving portion, one of the position adjusting mechanism and the receiving portion being on the bundle, and the other of the position adjusting mechanism and the receiving portion being on one of a base surface and the rail member.
Exhaust-gas turbocharger
An exhaust-gas turbocharger (1) with a bearing housing (2), a shaft (3) mounted in the bearing housing (2), a compressor wheel (5) arranged on the shaft (3) and a turbine wheel (4) arranged on the shaft (3), a housing component (7) which surrounds the compressor wheel (5) or the turbine wheel (4), and a sealing ring (14) between the bearing housing (2) and the housing component (7), wherein the sealing ring (14) is, in order to impart its sealing action, compressed in a direction perpendicular to the shaft (3).
Crimpless piston-slipper assembly
A piston-slipper assembly and method for assembling a piston-slipper assembly for use in a hydraulic apparatus such as a piston motor or piston pump. The assembly contains a piston and a slipper, and at least one of the piston or the slipper includes a ball and the other includes a socket. The ball is retained in the socket without crimping, swaging or bending of the socket.
Threaded connectors between submersible well pump modules
An electrical submersible pump assembly has modules including a pump, a motor, and a pressure equalizer. A first adapter having threads is mounted to one of the modules. A second adapter is mounted to an adjacent one of the modules, the second adapter having a tubular body, a neck, and an external shoulder at a base of the neck. A collar is rotatably carried on the neck and in threaded engagement with the threads of the first adapter. A clamp secures around the neck between the external shoulder and the collar after the collar is fully engaged with the threads on the first adapter. A pair of flanges are mounted to and extend outward from the clamp. A motor lead locates between the flanges.
Modular ejector pump for a fuel delivery device
A modular ejector pump (1) for a fuel delivery device (39). The ejector pump (1) has a feed line (3) and a first nozzle (7). The feed line (3) is embodied to supply fuel (27) to the first nozzle (7). The ejector pump (1) furthermore has a second nozzle (9), which is arranged parallel to the first nozzle (7). The feed line (3) is embodied to supply fuel (27) to the second nozzle (9).
TURBINE ABRADABLE LAYER WITH COMPOUND ANGLE, ASYMMETRIC SURFACE AREA RIDGE AND GROOVE PATTERN
Turbine and compressor casing/housing abradable component embodiments for turbine engines, have abradable surfaces with asymmetric forward and aft ridge surface area density. The forward ridges have greater surface area density than the aft ridges to compensate for greater ridge erosion in the forward zone during engine operation and reduce blade tip wear in the aft zone. Some abradable component embodiments increase forward zone ridge surface area density by incorporating wider ridges than those in the aft zone.
Pump having an automated gas removal and fluid recovery system and method
A precision pump system having a motor driver for accurately and repeatedly delivering process fluid, (e.g., photo chemicals) using a pumping fluid with minimal process fluid loss to a fabrication process and whereby the motor driver can be easily and quickly replaced without interrupting the fluid flow path. This is accomplished with the use of a process fluid reservoir and a pumping fluid reservoir that are associated with the pump, either integrated with the pump or closely adjacent. In addition, this precision pump system can be remotely monitored, viewed and controlled over the Internet. In addition, trapped process fluid within a downstream filtering block can be recirculated to the process fluid reservoir when trapped gas in the filter is removed. Furthermore, a nitrogen gas source is connected to the process fluid reservoir via a valve in case a need to insert a gas is required.
INFUSION PUMP ASSEMBLY
A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.
Pump fittings and methods for their manufacture
A pump fitting has an inlet adaptor (10) for connection to an outlet (39) of a container (38) of fluid and including an inlet passage (10), an outlet passage (11) for fluid and a pump housing (12) between the inlet passage (10) and the outlet passage (11). The pump housing (12) contains a rotor (17) rotatably received in an interior surface of the housing (12). The rotor (17) includes a housing-engaging surface (23, 24) co-operating with the interior surface of the housing (12) to form a seal therebetween and also including at least one shaped surface (21, 22) radially inwardly of the housing-engaging surface and forming with the interior surface of the housing a chamber (25, 26) for conveying fluid from the inlet passage (10) to the outlet passage (11) on rotation of the rotor (17). A seal (28) is provided between the outlet passage (10) and the inlet passage (11), the seal (28) being urged into engagement with the rotor (17) to prevent fluid passing from the outlet passage (11) to the inlet passage (10) as the shaped surface rotates. The inlet passage (10), the outlet passage (11) and the housing (12) are formed as a one-piece molding.
