20130167792 | SELF-LUBRICATING BALANCE SHAFT WITH FLOW CONTROL - A mass compensating shaft drive for compensating forces or moments of inertia of a reciprocating piston internal combustion engine is provided having a balance shaft supported by at least one journal in a housing of the internal combustion engine. A rolling bearing is located between each of the at least one journals and the housing. The balance shaft includes an oil gallery that is adapted to be connected to a source of pressurized lubricating oil. A check valve is located between the oil gallery and each of the at least one bearing journals, with the check valve being arranged to open upon at least one of a lubricating oil pressure or a centrifugal force generated through rotation of the balance shaft exceeding a predetermined closing force for the check valve. | 07-04-2013 |
20150027271 | ROCKER SHAFT WITH DIAMOND-LIKE CARBON COATING - A rocker shaft for a valve train of an internal combustion engine, including: a substantially cylindrical outer circumferential surface; and a layer of amorphous hydrocarbon deposited on the substantially cylindrical outer circumferential surface. The rocker shaft is arranged to engage a rocker arm such that the rocker arm is at least partially rotatable about the rocker shaft. A method of forming rocker shaft for a valve train of an internal combustion engine, including: forming a substantially cylindrical outer circumferential surface; and depositing a layer of amorphous hydrocarbon on the substantially cylindrical outer circumferential surface. The rocker shaft is arranged to engage a rocker arm such that the rocker arm is at least partially rotatable about the rocker shaft. | 01-29-2015 |
20150055907 | BEARING ASSEMBLY WITH A RETAINING RING AND METHOD THEREOF - A bearing assembly, including a housing with a first circumferentially disposed groove; a bearing including an outer race with a second circumferentially disposed groove; and a retaining ring disposed within the first and second circumferentially disposed grooves. A method of retaining a bearing, including: locating a first portion of a ring within a groove in an outer race; installing a housing radially about the race to contact the race; locating a second portion of the ring within a groove in the housing; bringing temperature of the housing and the race to a first level; fixing, with contact between the race and the housing, the race with respect to the housing; increasing the temperature of the housing and race to a second higher level; creating a radial gap between the housing and the outer race; and fixing, with the retaining ring, a position of the race with respect to the housing. | 02-26-2015 |
20150083062 | OUTER HOUSING FOR A HYDRAULIC LASH ADJUSTER WITH TAPERED OIL FEED ANNULUS - A hydraulic lash adjuster is provided. The hydraulic lash adjuster includes an outer housing having an annular body with an open first axial end, a closed second axial end, a radially inner wall defining an axial bore, and a radially outer wall. The radially outer wall includes a first annular groove located adjacent to the first axial end, and a second annular groove located adjacent to the second axial end. A first port is located in the first annular groove, and a second port is located in the second annular groove. A radially outer surface of the first annular groove tapers radially inwardly between a first axial end and a second axial end. | 03-26-2015 |
20150083063 | SWITCHABLE HYDRAULIC LASH ADJUSTER WITH EXTERNAL SPRING AND SOLID STOP - A valve train of an internal combustion engine with a switchable hydraulic lash adjuster (SHLA) is provided, including a cylinder head having a boss, with an opening defined in the boss. The SHLA is located in the opening, and the SHLA includes: an outer housing having an inner bore, an inner housing movably located in the inner bore of the outer housing, and including a spring retainer at an outer end thereof, and a plunger assembly with a hydraulic lash adjuster mechanism movably located in a bore of the inner housing. A lost motion spring is located between the spring retainer and a spring seat located around the boss. This arrangement reduces the overall packaging length of the SHLA in that only a fraction of the lost motion spring's installed height has an influence on the overall length of the SHLA. | 03-26-2015 |
