Abstract: A discharge tip for a fuel injection nozzle comprises a hollow body having a bore closed at one end and open at the other with the closed end being of reduced size relative to the open end and terminating in a partispherical tip exceeding a hemisphere connected with the remainder of the body by an annular necked down surface portion coaxial with the bore and intermediate the ends thereof and having a plurality of radially directed discharge passages in the partispherical portion of the tip with at least one of the orifices disposed in the portion of the partispherical tip outside the hemispherical portion which is concentric with the axis of the elongated bore.

Abstract: A new monovalve internal combustion engine of a design specially adapted for screw machine manufacture and including a valve support requiring no lubrication, a combination pull rod and fuel conduit secured to a reciprocating member of a two stage injection pump with the pull rod and both pumps operated by a single compound cam arrangement, a fuel injection nozzle concentric with the valve and with the combustion chamber and having no flexible connections, a fabricated piston rod assembly wherein the crankshaft bearing of the piston rod is greater than the throw of the crankshaft, a fluid seal between the piston and the cylinder against compression losses, a compression chamber which ensures an increasing turbulence of the charge in the cylinder with a maximum at top dead center, and a novel air blower and cleaner system including an arrangement for increasing the volumetric efficiency of the engine and the efficient purging of exhaust gases.

Abstract: 858,492. Filters. ROOSA, V. D. Feb. 6, 1959 [Feb. 20, 1958], No. 4232/59. Class 46. A filter, especially for liquid fuels, may be disassembled by manually turning a cap 11 having axially and non-rotatably mounted therein (by peening 71 and head - fitting socket 49 respectively) a bolt 13. Such turning releases the lower end of the bolt from the threaded bore 26 of the hub portion 17 of a base 10 whereupon a cartridge 12 consisting of imperforate outer cylinder 34, imperforate conduit 40, centrally-apertured end-plate 35, perforate end-plate 36 and paper element 43, may be lifted off the base. On removal of the cartridge a valve 58 is raised by a spring 60 to cover holes 55 in the hub 17 which normally permit filtrate to flow from conduit 40 to outlet passage 30. Unfiltered fuel introduced at 21 passes upwards through plate 36 and upwards through the folds of paper 43, filtrate flowing radially inwards under plate 35 and then through a spider 37 into conduit 40 and also between hubs 68 and 47 into the cap interior. Rubberlike members 52, 53 are bonded to the endplates of the filter cartridge.

Abstract: A form-sustaining disposable liquid fuel filter cartridge permanently confining a filter element has spaced apart noncoaxial ported resilient abutments on a flat wall of the cartridge housing facing in a common direction to provide a tripod mount for the cartridge and self-adjusting seals for the inlet and outlet passages provided by the ported abutments when the cartridge is mounted on its flat supporting base by a resilient sheet metal spring clamp exerting a biasing force offset from each of the abutments. The rectangular high capacity filter element within the cartridge is accordion pleated and longitudinally corrugated to bias the edges of the element against the walls of the cartridge to which the edges are bonded when the filter element is packed during assembly and to provide enlarged nonclogging entrance openings for the element. Filter elements may be placed in series in a single cartridge for dual filtering of the fuel and an automatically pierced initially sealed ported abutment used to keep contaminants out of the downstream side of the filter element before use.
