Embodiment Construction

[0021] As shown in FIG. 1 , the cylinder head 10 has a camshaft 14 held in contact with the cylinder head 10 by a plurality of shaft mounting means of the invention embodied as camshaft covers 22 . As fully described below, the oil required for the operation of the camshaft 14 is provided to the mounting device 22 through lubricant supply conduits formed in the cylinder head 10 .

[0022] 2 and 3 show the lubricant supply duct 54 formed in the cylinder head 10 . Lubricant flowing up through conduit 54 enters a lubricant inlet 58 formed in camshaft cover 22 . It should be noted that the cover 22 has a mounting base 30 which allows the cover 22 to be fixed to the cylinder head 10 by means of screws 38 . The cover 22 has a cap-shaped bearing body 26 with a semicircular hole 50 formed therein. Bore 50 cooperates with bore 52 formed in cylinder head 10 to define a bearing surface surrounding a portion of camshaft 14 . The portion of the camshaft 14 that is surrounded by the cams...

Abstract

A shaft mounting arrangement for an internal combustion engine includes a bearing body having a mounting base for engaging an engine structure and a semicircular bore provided by a lubricant distribution passage. A flow regulator integrated as part of the liquid choke is located in the lubricant distribution channel. Because the flow restriction is integrated, a separately machined flow restrictor can be eliminated.

Description

technical field [0001] The invention relates to shaft mounting devices for use in internal combustion engines. The device of the present invention provides both lubrication and fixation to the rotating shaft within the engine, with the flow of lubrication being controlled by an integrated flow restrictor contained within the bearing body portion of the shaft mounting device. Background technique [0002] Modern pressure-lubricated multi-cylinder internal combustion engines have a large number of bearings, which must be supplied with lubricant by means of a centrally located oil pump. As part of the engine development process, the amount of lubricant reaching each bearing must be carefully metered to ensure that all bearings are adequately lubricated without scheduling too much lubricant. [0003] Overfeeding lubricant to engine bearings is disadvantageous for at least two reasons. First, an oversized oil pump uses too much energy, which reduces fuel economy. Second, exces...
