摘要： High pressure fluid systems, such as those found in common rail fuel systems for engines, often need a low pressure containment system to appropriately address the possibility of fuel leakage around the engine. In addition, such high pressure systems also often require flow to go from one location, such as the common rail, to another location, such as a fuel injector, while undergoing a direction change because of spacial constraints around the engine. The present invention utilizes an elbow component with valve surfaces on its two faces that are oriented at about 90° with respect to one another. When the elbow component is fastened to the head with first fasteners and fastened to a flow limiter housing in another direction with second fasteners, a quill tube is compressed between the valve surface on the elbow component and a similar conical seat on a fuel injector in one direction while also compressing a short tube and flow limiter between the other valve surface of the elbow component and the common rail. The low pressure containment system is sealed with O-rings. The high pressure connection can be serviced without dismantling other engine components.

摘要： A fuel injection shutdown system for a fuel injected internal combustion engine having mechanical fuel injectors with a return spring and lifter bodies slidably disposed in lifter guides comprises a slot formed in the lifter guides to receive a hydraulic cartridge and a slot in the lifter bodies which registers with the slots in the lifter guides, but are longer, the hydraulic cartridge extends into the slots in the lifter bodies, as the lifter bodies are reciprocated by an injection cam and the hydraulic cartridge does not contact the slots in the lifter bodies and the hydraulic cartridges have a stop pin slidably disposed therein and have a hydraulic duct which when filled with pressurized hydraulic fluid causes the stop pin to extend from the hydraulic cartridge contact the top of the slot in the lifter body and hold the lifter body off the cam preventing the fuel injectors from injecting fuel into the engine in two engine revolutions and stopping the engine to prevent harm to the engine.
