Abstract: An actuation linkage assembly may include a first lever arm connected to one end of a shaft, a second lever arm connected at one end to another end of the shaft, a transition linkage connected to the other end of the second lever arm, and a bracket connected to the transition linkage. The transition linkage is configured to connect the bracket on a driver ring and to the shaft to transfer rotational motion about the axis of the shaft, from a linear motion received by an actuator, to a linear motion through the bracket causing rotational motion of the driver ring. The actuation linkage assembly is configured with high mechanical advantage. The actuation linkage assembly can be part of a movable inter-stage vane guide assembly in a compressor such as for example a centrifugal compressor, which may be part of a chiller such as in a HVAC system.

Abstract: An interstage throttle for a centrifugal compressor includes a flow guide plate, a throttle ring, a drive ring, and linkage assemblies. The flow guide plate includes guide vanes that form channels that direct working fluid in between stages of the compressor. The linkage assemblies connect the drive ring to the throttle ring such that rotation of the drive ring moves the throttle ring in an axial direction. Teeth of the throttle ring partially block the channels when the throttle ring is in an extended position. A method of operating a centrifugal compressor includes directing the working fluid discharged from the first stage to a second stage via channels in a interstage throttle. A centrifugal compressor includes a first stage with a first impeller, a second stage with a second impeller, and an interstage throttle fluidly connecting the first stage to the second stage.

Abstract: Systems and methods to clamp an impeller on a shaft in a centrifugal compressor. The embodiments as disclosed herein may include clamping individual impeller independently to the shaft, which may reduce the tolerance stack-up effect of a plurality of impellers. The impeller can be clamped to the shaft by positioning, for example, a relatively stiff support (e.g. a shaft locknut) on a front side of the impeller. The impeller can also be clamped to the shaft by a relatively flexible support to compensate for e.g. thermal expansion/contraction of the impeller. The embodiments as disclosed herein are particularly suitable for a multi-stage impeller.

Abstract: A terminal assembly configured to conduct current from an external power source to a hermetical motor-compressor unit. The terminal assembly includes a terminal board, at least one opening defined through the thickness of the terminal board, at least a conductive pin received in the opening, and an insulator having a convoluted contour. The insulator may be disposed over the conductive pin and spaced away from the terminal board.
