  • Patent number: 10371019
    Abstract: A rear plate is provided which encloses an axial end opening of a housing body. A lock pin is configured to travel forward and backward in a slide hole formed in a first vane of a vane member, and an annular lock-hole-forming part is press-fitted to a retaining hole in an inner end surface of the rear plate, forming a lock hole in the rear plate. A projection having a flat distal end surface is formed at one circumferential end side of an inner peripheral surface of the lock-hole-forming part. Recesses that are continuous with the inner peripheral surface of the lock hole are formed on corresponding sides of the projection in the circumferential direction of the lock hole. This allows smooth engagement of the locking pin in the lock hole, and permits smooth supply and drainage of hydraulic pressure to and from the lock hole.

  • Patent number: 10174636
    Abstract: A compressor assembly, and more in general relates to a compressor for a gas turbine providing a solution that teaches to locate within a cavity formed by the outer casing of the compressor and the inner vane carrier a separator element, or membrane, such to divide the cavity into two sub-cavities. This advantageously results in a more flexible design with respect to the positioning of the flange blow-off extractor and to the cavity sizing, as the flange position is not necessarily the boundary for the flow anymore as it would be without the separator element.

    Abstract: An integrated single-piece exhaust system (SPEX) with modular construction that facilitates design changes for enhanced aerodynamics, structural integrity or serviceability. The SPEX defines splined or curved exhaust path surfaces, such as a series of cylindrical and frusto-conical sections that mimic curves. The constructed sections may include: (i) a tail cone assembly fabricated from conical sections that taper downstream to a reduced diameter; or (ii) an area-ruled cross section axially aligned with one or more rows of turbine struts; or both features. Modular inner and outer diameter inlet lips enhance transitional flow between the last row blades and the SPEX, as well as enhance structural integrity. Modular strut collars have large radius profiles between the SPEX annular inner diameter and outer diameter flow surfaces, for enhanced airflow and constant thickness walls for uniform heat transfer and thermal expansion. Scalloped mounting flanges enhance structural integrity and longevity.

    Abstract: A valve lift adjustment arrangement for a mechanically-controllable valve drive arrangement includes a bearing shaft, a first roller, a second roller arranged on the bearing shaft, a camshaft arrangement, a valve lift adjustment device comprising a rotatable eccentric shaft, an intermediate lever arrangement, and a device. The intermediate lever arrangement comprises an intermediate lever with a working curve. The intermediate lever is mounted via the first roller to be movable in a slotted-guide track and to be operatively connected to the camshaft arrangement and to the valve lift adjustment device. The device is configured so that the second roller is eccentrically mounted. The device comprises a tool engagement point which aligns the second roller and thereby the intermediate lever arrangement. The camshaft arrangement acts, via the first roller, on the intermediate lever arrangement. The rotatable eccentric shaft is acts, via the second roller, on the intermediate lever arrangement.

  • Patent number: 8887688
    Abstract: An oil distribution and cooling system for diesel engines of the design represented by the 6.4L POWER STROKE® engine. The stock oil cooler and cover are removed and a manifold is positioned in place of the removed stock oil cooler and cover. The block has oil in, oil out, coolant in and coolant out ports which align with those on the engine. Coolant is directed to an adapter plate and a relocated oil cooler which may be the removed cooler or a replacement, preferably of the oil-to-air type. Oil to be filtered and cooled is directed through the manifold to a filter and then to the cooler. Cool, clean oil is returned to the manifold for distribution to various engine locations.

  • Patent number: 8839514
    Abstract: A method for machining, in particular mechanical machining, of at least one exhaust-gas-conducting surface region of an internal combustion engine or crankcase part, in particular at least one cylinder barrel of a crankcase or at least one cylinder barrel of a cylinder sleeve, includes using a surface-condition-changing machining tool. The surface region is produced from a corrodible material and is brought into contact, during the machining through the use of the surface-condition-changing machining tool, with at least one tribochemically activatable substance being activated during the machining in particular as a function of a defined contact pressure of the machining tool and/or as a function of a defined machining temperature, and forms a corrosion-resistant surface as a triboreaction layer with the respective surface region, by tribochemical reaction. A crankcase and a cylinder sleeve formed in this way are also provided.
