Abstract: An apparatus for and method of mounting a flange to an oil pickup tube uses a bracketed flange mounting (201, 203, and 205). The bracketed flange mounting includes a flange (203) with a flange extension (205) in connection with a bracket (201) that is mounted to an oil pickup tube (101) between its two ends. The bracketed flange mounting (201, 203, and 205) may couple to an engine crank case or oil pump inlet in the same way as prior assemblies without a bracketed flange mounting, thus no retooling of any other part of the engine is required.

Abstract: There is provided a hydraulic fuel system having an integrated and internally mounted oil circuit for providing high pressure in a hydraulically operated electronically controlled fuel injector fuel system. There is provide an internally mounted high pressure pump in a pump housing in the crankcase and connected to internally routed high pressure lines that deliver the oil to high pressure oil rails. There is provide an integrated low pressure oil reservoir in the crank case that comprises a low pressure oil cooler and reservoir. The oil cooler is preferably immersed inside the low pressure oil reservoir to optimize available engine space and improve heat transfer. There is also provided a high pressure pump filter that covers a high pressure pump inlet feed passage to prevent debris from passing into the high pressure oil pump and other components on the high pressure oil circuit.

Abstract: The present invention describes a filter screen for removing debris from the hydraulic actuating fluid in an internal combustion engine having a hydraulic pump for supplying hydraulic actuating fluid to hydraulically-actuated unit fuel injectors. An upper portion of a priming reservoir is mounted on a front cover of the engine. The front cover forms a lower reservoir portion. A screen assembly is positioned adjacent to an interface defining an entrance from the upper reservoir portion to the lower reservoir portion. The screen assembly includes a filter screen enclosing the entrance to force the actuating fluid to pass through the filter screen, thus retaining debris that exceed the mesh size of the filter screen.

Abstract: The present invention describes a filter gasket (50) for removing debris from the hydraulic fluid in an internal combustion engine (10). An upper reservoir structure (30) is mounted on a front cover (14) of the engine (10) at interface (46). The front cover forms a lower reservoir (16). The upper reservoir structure (30) forms an upper reservoir (35). A gasket (42) is disposed along the interface (46) to seal the upper reservoir structure (30) to the front cover (14). A screen assembly (70) is positioned adjacent to the interface (46). The screen assembly (70) includes a filter screen (76) connected to a plate member (56). The plate member (56) operatively engages the gasket (42). The plate member (56) forces hydraulic fluid to pass through the filter screen (76), thus retaining debris that exceed the mesh size of the filter screen (76).

Abstract: A diesel engine having a lubricating oil sump and a low pressure lubricating oil pump, is provided with a hydraulically-operated, electronically-controlled unit fuel injector operating system of the type having a unit fuel injector, a high pressure pump, a high pressure lubricating oil supply passage from said pump to said unit injector, a fuel supply to said unit injector, and an electronically controlled valve in said unit injector for controlling the application of the pressure of the lubricating oil to force said fuel to be expelled from said injector, wherein a priming reservoir is operatively connected to the low pressure lubricating oil pump and disposed upstream and above the high pressure supply pump and above the high pressure supply passage, preferably being disposed in the engine front cover and having a restricted return line to the oil sump for venting air from said reservoir, a siphon passage establishes fluid communication between said reservoir and said high pressure passage independently of

Abstract: A tandem fuel pump assembly for internal combustion engines includes a housing having a fixed spring retainer mounted thereinside which supports a diaphragm pump biassing spring thereabove to force a diaphragm defining the movable lower wall of a first pumping chamber to reduce the volume thereof and eject fuel from an outlet thereof preferably through a fuel filter to the inlet of a second piston pumping chamber. A second biassing spring supported below the spring retainer forces a pumping piston downwardly to reduce the volume of the second pumping chamber and thereby eject fuel therefrom to an engine fuel rail for injection into the engine therefrom.

Abstract: In an automatic tailgate of a dump truck a continuous single cable extends from a left side gate lever arm to a right side gate lever arm after passing below the dump body of the truck and being movably secured to the truck frame. When the dump body is in a dumping mode the continuous single cable will allow equalization of tailgate lifting forces.

Abstract: A grouser retainer that is positioned between a belt and a tire carcass provides an anchor for attaching one outboard end of a grouser to a tracked tire assembly. A pair of grouser retainers, one at each edge of the track or belt, are used to anchor each grouser as each grouser retainer is less than the full width of the tire tread.
