Abstract: In a light source of a reflective type LED, a light-emitting element is mounted on the bottom surface of a concave reflecting mirror. Accordingly, light emitted horizontally from the light-emitting surface of the light-emitting element is also reflected by the reflecting mirror, so that all components of light emitting from the light-emitting element are concentrated on a region within a predetermined extent from an axis perpendicular to the light-emitting surface so as to irradiate the region. Thus, the end portion of the reflecting mirror provided in opposition to the light source need not be made close to the height of the light-emitting surface of the light-emitting element 2 in the light source. Hence, it is possible to obtain high external radiating efficiency even in the case where the reflecting mirror is provided far from the light-emitting element. Thus, the degree of freedom for designing the reflecting mirror increases, so that the reflective type light-emitting diode can be widely applied.

Abstract: A piston engine employing a flywheel rotor, in lieu of a crankshaft, driven hydraulically by the piston. One end of a plunger is connected to the piston, the other end being slidably disposed in an hydraulic cylinder. In the combustion mode, fuel and oxygen are injected and spark ignited, both by the same variable speed D.C. speed control motor. The piston-driven plunger displaces hydraulic fluid in the cylinder through a high speed orifice to impinge against spaced cavity surfaces formed along the periphery of the flywheel rotor, thereby spinning the rotor. A slide valve is disposed in the orifice and is hydraulically connected to the cylinder so that pressure changes in the cylinder reciprocate the slide valve to provide momentary delay, during pressure build-up, and then release of the cylinder fluid, thereby increasing the fluid velocity. Hydraulic fluid is recirculated during an exhaust stroke wherein the piston is returned by injected air pressure.

A second piston is powered to assume an axial position indicative of the quantity of fuel being delivered by the pump.

Abstract: The fuel feed device comprises a butterfly valve actuated by the driver and an auxiliary throttle member which opens automatically in proportion to the rate of air-flow in the intake passage of the engine. The pressure of the fuel which is delivered into the intake at a location downstream of the butterfly by an injector is adjusted by an unloading valve. The fuel pressure tends to open the unloading valve and the under-pressure which prevails in a control chamber tends to close it. The control chamber has a connection with a portion of the intake which is located downstream of the auxiliary throttle member. That connection is open when the under-pressure is moderate. The connection has also a branch connected to an additional air channel for cold running of the engine which is open when the temperature of the engine is lower than a predetermined value.

Abstract: In an internal combustion engine employing manifold fuel injection, the air flow rate through the induction manifold controls the motions of a slide in a metering and distribution valve assembly. The slide, in turn, controls the effective metering valve apertures of several individual openings, each leading first to an equal pressure diaphragm valve and, hence, to individual fuel injection nozzles.The system includes a differential pressure control valve, which maintains a constant pressure difference across the metering valve apertures in the metering and distribution valve assembly. The differential pressure control valve may be in parallel or series connection with the several equal pressure diaphragm valves. The system also includes a pressure control valve, responsive to engine parameters, which adjusts the resetting force acting on the control slide in the metering and distribution valve assembly.
