摘要:
A separable gasket for use in sealing the interface between a gear housing and an engine block as well as the interface between an air compressor and the gear housing includes a first gasket portion constructed and arranged for sealing the interface between the gear housing and the engine block and a second gasket portion constructed and arranged for sealing the interface between the air compressor and the gear housing. A third gasket portion in the form of a perforated score line is positioned between the first gasket portion and the second gasket portion. In the event the air compressor requires servicing, the present invention enables the second gasket portion to be manually flexed and ultimately separated from the first gasket portion so that a replacement gasket can be assembled when the air compressor is reassembled to the gear housing. By separating the second gasket portion from the first gasket portion, the servicing of the air compressor does not necessitate any disassembly of the gear housing from the engine block nor any replacement of the first gasket portion.

Apparatus and method for adjusting a gear in a gear train assembly. A first gear with a first rotational center and a second gear with a second rotational center are coupled to an engine. A third gear with a third rotational center is provided to form a first mesh with the first gear. The first mesh has a predetermined minimum backlash. The third gear also forms a second mesh with the second gear. The third gear includes an adjustable positioning mechanism which allows the rotational center of the third gear to be adjusted along a predetermined adjustment path that is substantially tangent to the first mesh. The adjustment mechanism of the third gear allows the minimum backlash of the first mesh to be maintained while the second mesh is adjusted to likewise achieve a generally minimized backlash.

In an internal combustion engine, a barring adapter member is mounted on an auxiliary engine component, such as an air compressor shaft which is geared to the engine crankshaft. The barring adapter member is configured to receive a barring tool, permitting manual rotation of the air compressor shaft for desirably positioning engine crankshaft-driven components during engine repair or adjustment. In an arrangement according to the invention, the air compressor gear is enclosed by a gear casing, but the adapter is accessible through an aperture closeable by a removable cap. The barring adapter member facilitates barring the engine from a convenient position and is particularly advantageous in an engine designed to eliminate most externally-exposed rotational shaft seals and associated external pulleys conventionally used as barring locations.

One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.

A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

A ceramic-metal composite structure which minimizes tensile ceramic loads and accommodates differences in thermal expansion characteristics between a metal member and a ceramic member without reliance on precise feature control for either member. The composite includes a mechanical retainer which allows a loose fitting relationship between the metal and ceramic members. The ceramic member is secured within a receiving bore in the metal member by the retainer in a manner which eliminates the need for precise machining of the ceramic and metal members. The metal member may be configured to accept either an internal or an external mechanical retainer element. The composite ceramic-metal structure of the present invention finds particular utility in forming a durable wear-resistant interface in internal combustion engine actuator or actuating components, such as compression brake master pistons.

An improved two-piece connecting rod (800) that connects a reciprocating piston with a crankshaft in an internal combustion engine. The connecting rod (800) has a shank portion (810, 860), a cap portion (820, 870) and projections (830, 880, 882) extending from one or both of the shank (810, 860) and cap portions (820, 870). When the shank (810, 860) and the cap (820, 870) are connected, the projections (830, 880, 882) mate with the opposite side with an interference fit, thereby resisting relative motion between the shank (810, 860) and the cap (820, 870) along the split-line (A′).
摘要:
An engine system with a gear train to provide engine timing is disclosed. A technique to minimize backlash and noise caused by the gear train is included. An anti-backlash gear assembly useful to reduce backlash in the gear train is also disclosed. One disclosed gear assembly has at least two gear wheels with the circular thickness of the teeth of one gear wheel being less than the circular thickness of the other gear wheel. A gear assembly is also disclosed that has a bias torque of at least about 100 foot-pounds. A device carried on an anti-lash gear assembly to generally align teeth of the assembly for installation is also provided.
