A conduit mounting system includes a plurality of modular components. Each modular component includes first and second transverse sides that are spaced apart and substantially parallel with one another and third and fourth longitudinal sides that are spaced apart and substantially parallel with one another. The third and fourth longitudinal sides extend between the first and second sides. Each modular component also includes a fifth side disposed between the first and second sides and between the third and fourth sides. The fifth side includes a conduit support surface disposed between first and second side contact portions. Each modular component also includes a flange having a first flange portion extending beyond a surface of the third side and a second flange portion extending beyond a surface of the first side contact portion of the fifth side. Each modular component further includes a groove having a first groove portion formed in the fourth side and a second groove portion formed in the second side portion.

Conduit mounting system

An adjustment device for changing the relative rotation between a cam and a crankshaft is provided. The adjustment device includes a driven device operatively connected to the crankshaft. The driven device has a first plurality of channels directed radially inward toward a central axis. The adjustment device also has a hub axially aligned with the driven device along the central axis and connectable to the cam. The hub has a second plurality of channels directed inward toward a point radially offset from the central axis.

Adjustable valve timing system

The present invention broadly applies to any fluid valve made up of a plurality of body components that create sealing lands where the body components are clamped together. The invention is further applicable to any such valves in which pressure differentials within the valve can cause fluid leakage in the region of these sealing lands. Fluid leakage is reduced by locating at least some of these sealing lands within a hollow clamp that holds the valve body components together. This clamping strategy that locates the clamping load where it is needed most is applicable to a wide variety of valves, but is particularly applicable to pressure control valves used in fuel injection systems that experience extremely high pressure differentials during their usage.

Valve assembly and fuel injector using same

The present invention relates to high speed control valves which are especially applicable for use in fuel injection systems. Producing a valve with a quick response time within acceptable packaging constraints and with a structure that allows the valve to be mass produced with consistent performance between valves is extremely problematic. By moving flow restrictions within the valve away from the valve seats, flow forces on the valve member can be reduced, while possibly also permitting a reduction in the necessary travel distance of the valve member to improve response time and other performance characteristics. The valve is particularly applicable in controlling hydraulic pressure applied to the closing hydraulic surface of a direct control needle valve in a fuel injector.

Three way valve and electro-hydraulic actuator using same

Particularly in the fuel injector art, two components may define a high pressure space that is sealed against leakage via a planar sealing land between the two components. If a leak develops in the planar contact area between the two components, it can act to wedge the two components apart, which tends to exacerbate the leakage problem, and so on. Since some leakage between the two components is almost inevitable for a variety of reasons known in the art, a strategy that arrests the leak before it can produce the component separating wedge affect would be beneficial. This can be accomplished by positioning a leak arrest volume, which may be vented, around a majority of the perimeter of the high pressure space. The usage of a leak arrest volume finds particular application in fuel injectors, especially a class of common rail fuel injectors that are maintained at high pressure during prolonged periods between injection events.
