  • Patent number: 11506156
    Abstract: An air intake assembly has an inlet member, a fluid reservoir, and an outlet. The inlet member defines a generally vertical oriented first fluid channel. The first fluid channel has a vertically extending portion, an upper inlet end, and a lower end. The fluid reservoir has an upper region that defines a second fluid channel. The fluid reservoir is attached to a lower end of the inlet member such that the first fluid channel vertically extending portion is substantially perpendicular to the second fluid channel. The fluid reservoir has an outlet defined by an aperture in a lower region of the fluid reservoir which forms a liquid collector. The trapdoor is pivotably attached to the fluid reservoir adjacent to the outlet. The rigid trapdoor is configured to open when exposed to a predetermined open force value to allow liquid to escape the liquid collector.

  • Patent number: 9657783
    Abstract: A clutch module for a dual clutch transmission (DCT) is designed to improve circumferential fluid distribution to reduce or eliminate an unpleasant noise during engagement. In some embodiments, the reaction plate is restrained in a position offset 1-3 degrees from perpendicular to the housing axis. Consequently, 0.2-0.7 mm of clearance remains on one radial side of the clutch when all clearance has been removed on the other radial side of the clutch. Relative rotation between the hub and the housing pushes fluid from the tight side toward the loose side. In an alternative embodiment, the piston is designed to orient the pressure plate non-perpendicular to the housing axis.
