  • Patent number: 3937198
    Abstract: A vacuum controlled valve either in series or parallel with the customary bleed orifice in the vapor flow path from the fuel tank to the charcoal canister of an automobile evaporative control system opens when the engine is operating to direct fuel vapor flow from the tank to the fuel-air inlet induction conduit, thereby to prevent excessive fuel vapor pressure in the tank that would otherwise be released to the atmosphere via the customary pressure vented closure cap for the fuel tank filler spout.

  • Patent number: 3937195
    Abstract: A fluidic implementation of a constant mass airfuel ratio fuel-injection system which may be utilized, for example, in an internal combustion engine. The system includes a fluidic mass air flow sensor that produces a pressure oscillation in direct proportion to the mass air flow to the engine. The frequency of this oscillation is utilized to control a fuel flow metering device which delivers a fixed amount of fuel per oscillation cycle. In one preferred embodiment, the metering device may comprise a fixed displacement piston pump. In an alternative embodiment, the metering device comprises a constant pulse-width fluidic amplifier.

  • Patent number: 3935852
    Abstract: A module for use in the ignition system of a spark ignited engine combines in one unit a spark plug connector or cap and an ignition coil for converting low voltage current changes into the high voltage pulses required for firing the associated plug, the module, therefore, eliminating the need for a separate high-tension conductor of substantial length between the ignition coil and the spark plug. The module is mounted to an engine shroud directly outboard of the spark plug so as to electrically cooperate with the plug while nevertheless not relying on the plug for its structural support.

  • Patent number: 3933133
    Abstract: An improved fuel injector for a turbine, the injector comprising a conical cup adapted to be rotated and a means for depositing fuel on the internal surface of the cup. When the cup is rotated the fuel is caused to be spread uniformly over the internal surface of the cup as a thin film due to centrifugal force. An air blast is provided externally of the cup and parallel thereto, whereby the fuel reaching the lip of the cup is atomized and directed outwardly at a controlled spray angle. During turbine ignition an air blast is not utilized, thereby allowing a constant spray angle of 180 degrees and permitting the accurate fixed location for the ignition system.
