Abstract: A hub-driveshaft assembly comprises a hub and driveshaft with a flat portion having a width. The hub comprises a body having an axial bore therethrough, a set screw hole extending radially through a wall of the body and communicating with the axial bore, and an alignment feature positioned near an entrance to the axial bore, wherein the alignment feature substantially aligns the flat portion of the driveshaft with the set screw hole when the driveshaft is inserted into the axial bore. In another embodiment, the hub comprises an alignment feature to promote proper alignment of the driveshaft with respect to the hub when the driveshaft is inserted into the axial bore, wherein the alignment feature is eliminated under load. In yet another embodiment, the hub comprises an alignment feature that flattens in response to loading from the driveshaft.

Abstract: A distributor assembly has a distributor extending along a central axis between a first end and a second end opposite the first end. The distributor has a flow passage extending from the first end of the distributor and a plurality of feeder ports extending from the second end of the distributor to the flow passage and each feeder port is in fluid communication with the flow passage. Each feeder port extends along a central axis from a first end at the flow passage to a second end at the second end of the distributor and each feeder port comprises a first axial segment and a second axial segment, the first axial segment being connected between the flow passage and the second axial segment and the second axial segment being connected between the first axial segment and the second end of the distributor.
