  • Patent number: 10927696
    Abstract: A gas turbine engine includes a compressor section having a first portion and an aft portion. A compressor case clearance (CCC) control system is configured to adjust an amount of bleed air delivered to the front portion and the aft portion based on an in-flight phase of an aircraft. In response to invoking a first mode, the CCC control system delivers air to both the front portion and the aft portion. In response to invoking a second mode, the CCC control system reduces the amount of air delivered to the aft portion prior to transitioning from the cruise phase to the descent phase. Accordingly, clearance areas within the compressor section can be selectively increased during specific portions of the flight to avoid contact between blade tips and the engine case.

  • Patent number: 10378553
    Abstract: An improved variable geometry diffuser (VGD) mechanism for use with a centrifugal compressor. This VGD mechanism extends substantially completely into the diffuser gap so that the VGD mechanism may be used more fully to control other operational functions. The VGD mechanism may be used to minimize compressor backspin and associated transient loads during compressor shut down by preventing a reverse flow of refrigerant gas through the diffuser gap during compressor shutdown, which is prevented because the diffuser gap is substantially blocked by the full extension of the diffuser ring. During start-up, transient surge and stall also can be effectively eliminated as gas flow through the diffuser gap can be impeded as load and impeller speed increase, thereby alleviating the problems caused by startup loads at low speeds. The VGD mechanism can be used for capacity control as well so as to achieve more effective turndown at low loads.

The second biasing apparatus provides a second biasing force to the damper block, biasing the damper block a second deflection distance in a direction toward the hot gas path and away from the outer shroud. The second deflection distance is greater than the first deflection distance.

  • Patent number: 9845723
    Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The inlet-adjustment mechanism includes a variable-geometry conical mechanism comprising a plurality of vanes that in the closed position collectively form a frusto-conical inlet member having a trailing edge inner diameter that is smaller than an inner diameter of the shroud surface of the compressor housing at the inducer portion of the compressor wheel such that an effective diameter of the air inlet at the inducer portion is determined by the trailing edge inner diameter of the variable-geometry conical mechanism. The vanes in the open position are pivoted radially outwardly so as to increase the trailing edge inner diameter of the inlet member and thereby increase the effective diameter of the air inlet at the inducer portion.

  • Patent number: 9488190
    Abstract: A pump for immersion in a fluid reservoir has an extensible body and a fluid conduit. The length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. The pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump has a bottom housing with a bottom inlet and at least two, preferably at least three, tangential fluid outlets that are upwardly angled towards the conduit. The outlets may be merged with the fluid conduit. An impeller within the housing is shaped to transfer fluid tangentially and upwardly within the housing to co-operate with the upward angle of the outlets. These features reduce fluid pressure loss and thereby increase fluid flow rate through the pump for a given input power.

  • Patent number: 9364779
    Abstract: The method and equipment relates to the measurement of deflections of filter sectors in a disc filter. The filter discs in the disc filter are constituted by a number of filter sectors, and the distance between a position fixed relative to the filter, most commonly the scraper itself, and the filter surface is conventionally measured by manual measurement methods. The equipment is instead used that has a measuring head with a quick-release coupling for its mounting fixed in the filter, and a position sensor in the measuring head that measures the distance between the measurement arrangement and the surface of the filter disc in order to form momentary measurement results. The momentary measurement results are transferred by a data transfer link from the measurement arrangement to a data collection unit PC that has a memory.
