  • Patent number: 9951688
    Abstract: A low pressure shaft is provided for interconnecting a fan or low pressure compressor of a gas turbine engine with a low pressure turbine of the engine. The shaft has an aft section whose diameter expands progressively with distance along the rearward direction of the engine. The shaft further has an annular joint portion at the rear end of the aft section for joining the shaft to a drive arm of the low pressure turbine. The rate of expansion of the diameter of the aft section decreases with distance along the rearward direction of the engine.

  • Patent number: 9932981
    Abstract: The present invention is directed to a pump and motor assembly assembled in a waterproof enclosure with external threaded connections for pump suction and discharge. The motor can be directly connected to a flexible coupling to a bi-rotational internal gear pump, having self-adjusting mechanical seals and cast iron housing. The pump and motor assembly can be mounted on a sliding base for easy access. Flex hoses can be used to connect pump suction and discharge to couplings attached to the pump enclosure. A discriminating leak detector can be installed at the low point of the pump enclosure to detect and annunciate the presence of oil and/or water.

  • Patent number: 9816512
    Abstract: A product usable with a turbocharger may include a compressor wheel having an inducer section and an exducer section. Air may be collected by the inducer section and expelled by the exducer section. A cover may define a diffuser and a collection volute. The diffuser may lead away from the exducer section to the collection volute. The cover may define a collection cavity opening to the collection volute through a port and extending in an axial direction. The cover may define an inlet passage around the inducer section and the cover may include a dividing wall separating the inlet passage from the collection cavity.
