  • Patent number: 10378673
    Abstract: An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

  • Patent number: 10329970
    Abstract: A modified rocker assembly having an offset end is designed for engine heads having an obstruction preventing use of a symmetric switching rocker arm. The modified rocker assembly has an obstructed side and a non-obstructed side and has an outer structure with a first end, and an inner rocker structure fitting within the outer structure, the inner structure also having a first end. The modified rocker assembly has an axle pivotally connecting the first ends of inner structure to the outer structure, such that the inner structure pivots within the outer structure around the axle. At least one torsion spring on one side of the axle rotationally biases the inner structure relative to the outer structure. The outer structure is offset on the obstructed side as it extends from the second end toward the first end, creating the first offset portion to provide additional clearance on the obstructed side.

  • Patent number: 10330187
    Abstract: A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a sump and a motor. The hydraulic control unit housing has an accumulator housing portion that houses a biasing assembly and a piston. The sump is defined in the hydraulic control unit housing and at least partially occupies a common space with the accumulator housing portion. The motor is configured to pump fluid into an accumulator chamber of the accumulator housing portion. The fluid pumped into the accumulator housing portion at least partially collapses the biasing assembly and introduces a pre-charge into the hydraulic control unit. The biasing assembly is configured to expand and urge the piston in a first direction resulting in fluid being communicated from the hydraulic control unit and into the limited slip differential.
