摘要: A probe is used to detect axial movement of a rotating part such as a shaft. The probe includes a probe tube portion that protrudes into an annular groove on the rotating part. When the rotating part moves axially, one or the other side surfaces of the groove contacts the probe tube. This contact leads to a changed state of the probe, that is sensed by a sensor.

摘要: A system or method for sensing rotational parameters of a rotating machine. A rotating element is mounted on a shaft of a rotary machine. The rotating element has predetermined magnetic permeability. An insert is disposed on the first rotating element and characterized by a second magnetic permeability different from that of the rotating element. A sensor is mounted opposite the first rotating element and separated from the rotating element by a gap. The target element has an axis substantially parallel with and offset from the axis of the rotating element. The sensor is disposed in substantial alignment with the target element at least once per rotation when the rotating element is rotating. The sensor is configured to generate an output signal in response to a sensed deviation in a magnetic field induced by the rotation of the target element in proximity to the sensor.

摘要: A system for stabilizing the flow of fluid in a variable capacity compressor having a diffuser, the capacity of which can be varied by changing the relative position of fixed diffuser surface and a movable diffuser surface. The system includes an annular push ring connected to the movable diffuser surface by a plurality of pins. The annular push ring is axially displaceable and rotatably fixed. Axial displacement of the annular push ring axially displaces the movable diffuser surface. The system also includes a drive ring mounted on a nozzle base plate for driving the annular push ring. The drive ring is axially displaceable and rotatable. Rotation of the drive ring axially displaces the drive ring, the push ring, and the movable diffuser surface.
