  • Publication number: 20200325943
    Abstract: A driveline component with a shaft, a friction clutch and a centrifugal valve. The shaft has a supply passage and a feed passage that intersects the supply passage. The centrifugal valve has a valve seat, which is formed on the shaft and intersects the feed passage, a valve element and a flyweight that is pivotally coupled to the shaft. The valve element is received in the valve seat and is movable between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is displaced from the valve seat. The flyweight has a weight and a cam and is configured so that radially outward rotation of the weight in response to centrifugal force causes the cam to drive the valve element toward the first position.

  • Publication number: 20200164392
    Abstract: An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

  • Patent number: 10476351
    Abstract: A drive module with a housing, an electric motor coupled to the housing, a differential assembly, a transmission, and a filter-strainer assembly. The housing has an exterior wall member that defines an internal cavity and a suction tube. The internal cavity at least partly forms a lubricant sump with a sump outlet. The suction tube is spaced apart from and does not intersect the internal cavity such that the suction tube is not in direct fluid communication with the internal cavity. The differential assembly and transmission are received in the internal cavity and the transmission transmits rotary power between the electric motor and the differential assembly. The filter-strainer assembly is coupled to the housing and has a filter-strainer inlet, which is coupled in fluid communication to the sump outlet, and a filter-strainer outlet, which is directly coupled in fluid communication to a suction tube inlet of the suction tube.
