20190309666 | LUBRICATION OF BACKS OF CAMS BY OIL RECOVERY - A valve actuating device includes a camshaft, a cam, and a lubricant conducting device. The camshaft has an oil supply duct extending in a longitudinal direction of the camshaft and a discharge orifice extending in a radial direction of the camshaft and in fluid communication with the oil supply duct. The cam is fixedly mounted to the camshaft to rotate with the camshaft, the cam having a contact surface and a lateral wall facing in an axial direction of the camshaft towards the discharge orifice. The lubricant conducting device is arranged to direct oil over the lateral wall of the cam towards the contact surface. | 2019-10-10 |
20190309667 | Modular Assembly Having Press-Fit Fastener Holes - A modular assembly having a press-fit fastener hole. The press-fit fastener hole may include a plurality of lobe regions and a plurality of contact regions that may be spaced between lobe regions for a press-fit engagement with a fastener. The fastener may have a first diameter and the contact regions collectively may define an imaginary second diameter that is less than or equal to the first diameter. | 2019-10-10 |
