Title: Booster type unit injector
Inventor: TAIRA SHIGEO
IPC: F02M57/02
Filed: 1988-05-10
Abstract: PURPOSE:To damp a plunger utilizing the fuel and prevent secondary injection due to the bouncing of the plunger by gradually releasing the fuel of a pressurization chamber to the low pressure side as the plunger is moved in the pressurization direction after the fuel pressure feed is completed. CONSTITUTION:When a plunger 3 is lowered, the fuel of a pressurization chamber 7 is fed to a nozzle via a pressure feed passage 19 and injected. When the upper end 11b of the first pressurization section 11 becomes lower than the upper end 16b of a fuel pressure feed chamber 16 as the plunger 3 is lowered, the fuel pressure feed chamber 16 is communicated to a cutoff chamber 15, the fuel pressure feed to the nozzle is completed. When the lower end 11a of the first pressurization section 11 becomes lower than the lower end 16a of the fuel pressure feed chamber 16 in this case, the pressurization chamber 7 is communicated to a group 17 via a communication path 14 and the second small-diameter section 12, fuel is released to the low pressure side via a return passage 22 and an orifice 21. The plunger 3 is damped while the fuel of the pressurization chamber 7 is prevented from becoming excessive, and secondary injection is prevented.

Filed: 1982-06-30
Abstract: PURPOSE:To prevent a filter from damage, by arranging separators so that the wavy shapes of the wave-shaped separators adjoining to each other through a filter paper cross each other, and increasing supporting points of the paper. CONSTITUTION:A separator S1 under a filter paper is bent to slant in the direction of its bent wavy-shape with respect to its longitudinal direction so that the slant is reverse to that of a separator S2 adjoining oppositely to the separator S1, and is assembled into a filter. Separators S are arranged so that the wavy shapes cross each other, and the wave crest of a separator S1 sticks oppositely to the wave crest of an adjoining separator S2. Thus, the filter paper F is oppositely supported at >=2 points because the wavy shapes of the adjoining separators are intersected with each other, and then the structure of the paper F is strengthened. Further, vent holes H provided to the separator S enable the passing of air between the upper and lower spaces of the separator S and equalize the resistance of air flow generating between two sides of the separator.

Abstract: PURPOSE:To eliminate the need for a cylinder and reduce the weight and volume and then uniformly supply liquid fuel to the fuel chamber of each unit battery by providing a fuel pump and an electromagnetic opening and closing valve while being linked directly with the laminated battery of a liquid static type liquid battery and a pressure regulating valve at the reverse side. CONSTITUTION:Since liquid fuel is stored in a fuel tank 1 and an electromagnetic opening and closing valve 3 is opened usually, the liquid fuel supplied by a fuel pump 6 is not supplied to a laminated battery 4, but it passes through a bypass. When the liquid fuel in the laminated battery 4 is consumed, the electromagnetic opening and closing valve 3 is closed. The liquid fuel is pressurized to the pressure preset by a pressure regulating valve 7 and supplied to the fuel chamber of each unit battery in the laminated battery 4. When the battery voltage is restored up to the normal value and the fuel concentration in the fuel chamber is restored to the preset value, the electromagnetic opening and closing valve 3 is opened and the supply of the liquid fuel is stopped. That is, since pressurized gas is not required for fuel supply, any high pressure cylinder is not required.
