摘要： An oil control ring assembly having a sealing ring and a scraping is disposed within a groove in a piston. The scraping ring assembly has a scraping end portion and spaced apart ends defining a gap. The sealing ring has a sealing end portion and mated spaced apart radially stepped ends defining a stepped gap. The sealing end portion is connected to the scraping end portion and the stepped gap on the sealing ring is offset from the gap on the scraping ring. A spring applies a radial force to the scraping ring which urges the end portion of the scraping ring into engagement with the cylinder wall and a reaction force moment about the end portion forces the end portion of the of the seal ring into contact with an upper surface of the groove. The oil control ring assembly simultaneously provides for side and gap sealing.

摘要： A bypass restrictor arrangement is provided for use in a distribution valve to control the rate of bypass flow thus effectively reducing cavitation in a fuel system at the end of the injection stroke. Others primarily rely on operation at low system pressure or they rely on a relief valve to maintain a predetermined pressure level in the bypass passage. In the subject arrangement, an orifice is located in a bypass port of a rotor prior to the bypass fluid communicating with a low pressure chamber. Furthermore, the low pressure chamber is maintained at a predetermined pressure level by a relief valve. This arrangement ensures that the rate of fuel flow during bypass is controlled while also flushing and/or controlling the size of any entrained air bubbles or voids thus increasing the efficiency of the fuel system.

摘要： An apparatus and method for filtering particulate from an internal combustion engine by use of monolithic particulate trap systems having porous walls (2c, 24c). The porous walls (2c, 24c) filter the particulate. The filtered particulate on inner surfaces of the porous walls is periodically removed or regenerated via back flow of previously filtered exhaust gas. The back flow is caused by creating a pressure difference across the porous walls. The back flow of the previously filtered exhaust gas is simultaneously or sequentially coupled with high velocity through flow of exhaust gas in the channels. In addition, the particulate trap system can be an adsorber-catalyst particulate trap system for filtering particulate and reducing NOx via an adsorber-catalyst trap systems to achieve the EPA 2007 standards.

摘要： The design and construction of past piston assemblies having a wrist pin bolted to a connecting rod had excessive structural components requiring more complex machining procedures and tooling. Additionally, the loading and bolting patterns allowed the wrist pin to flex about the central axis of the piston assembly causing ultimate failure of the design. The present invention overcomes these problems by providing a piston assembly utilizing a bifurcated connecting rod and a piston having a pair of outer legs and a central leg. The outer legs and the central leg contact a wrist pin in three locations substantially distributing the forces across the wrist pin uniformly. A connecting means centrally connects the piston assembly shortening the overall length of the piston assembly. This results in a simplified forging or casting process, a more easily machinable piston, and a higher reliability design with improved load capacity.

摘要： In the use of fuel injection pumps, a distributing rotor is often utilized to sequentially deliver fuel from an inlet to a combustion chamber on an engine in combination with one or more reciprocating high pressure pistons. Due to the positioning of the various passages through which the fuel is directed, cavitation of the pump is often experienced which has a very serious effect on the life of the components within the pump. The fluid distribution apparatus of the present invention provides a single delivery passage between the pumping chambers of the reciprocating pistons and the distributing rotor. With this arrangement, fluid that is communicated from the bore to the pumping chambers in response to the intake stroke of the pistons is directed back through the same passage during the pressurization stroke of the pistons. The positioning of the single delivery passage prevents the fuel injection pump. The positioning of the single delivery passages prevents the fuel injection pump from experiencing the severe cavitation that is common with previous designs and thus the fore-shortened life of the pump components.
摘要翻译：在使用燃料喷射泵时，通常使用分配转子来将燃料从一个入口到发动机上的一个燃烧室依次传送到一个或多个往复运动的高压活塞。由于燃料被引导通过的各种通道的定位，经常经历泵的空化，这对泵内部件的寿命具有非常严重的影响。本发明的流体分配装置提供往复式活塞的泵送室和分配转子之间的单个输送通道。利用这种布置，在活塞的加压冲程期间，响应于活塞的进气冲程从孔传递到泵送室的流体被引导回通过相同的通道。单个输送通道的定位防止燃料喷射泵。单个输送通道的定位防止燃料喷射泵经历与先前设计相同的严重空化，从而使泵部件的寿命缩短。

摘要： Previously disclosed distributor fuel injection pumps for internal combustion engines offer the advantages of reduced size, weight, and cost of a fuel injection system. However, these pumps have not been able to provide relatively high fuel injection pressures which could improve fuel combustion for better fuel economy and lower noxious emissions. In contrast, the subject distributor fuel injection pump generates relatively high fuel injection pressures in a relatively compact arrangement. A semi-spherical nutator member freely rotatably mounted on an oblique journal of a drive shaft imparts high speed harmonic motion to at least one reciprocating pump plunger for pressurizing the fuel. A relatively large semi-spherical bearing interface between the nutator member and a pump housing accommodates very high pumping reaction loads. A distributor rotor for sequentially delivering the pressurized fuel to more than one engine combustion cylinder is rotatively driven by a planetary gear reduction mechanism coupled to the drive shaft. Very little force is required to adjust either the timing or quantity of fuel injection which are adjustable by angular movement of at either a normally stationary planetary ring gear or a fuel metering collar, respectively.
