ABSTRACT:
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.
