Abstract: An improved fuel injector for an internal combustion engine generating very fine atomization of fuel even at the initiation of a valve opening event and including a cylindrical valve element terminating in a semi-spherical end portion which engages a valve seat to close the injector. The fuel quantity is controlled by maintaining the valve in an opened operative positions for a predetermined variable period of time. Fuel atomization in the form of very small particles is generated by providing an annular chamber upstream of the valve seat, this annular chamber being very narrow and short as to form an insignificant volume of fuel even when the valve is closed and the fuel motionless.

Abstract: In association with an internal combustion engine having an intake manifold with an inlet opening at one end, an air pump of the type including an impeller on a rotatable shaft and a discharge opening, with the air pump mounted directly to the manifold so that the manifold's inlet opening and the pump's discharge opening are registered thereby allowing air to flow from the pump directly into the manifold interior.

Abstract: An electric shift mechanism for an automotive transmission mechanism is disclosed in which a manual selector lever is universally mounted on a support adapted for sequentially pivoting north-south and east-west swingable rockers about associated intersecting axes. A gate limiting plate formed with a predetermined shift pattern is mounted on the support intermediate the rockers. The lower end of the lever has a ball follower for pre-loaded travel on a single cam track supported longitudinally on the east-west rocker. The cam track is contoured to simulate shift effort stability and feel of conventional manual gear shifting operations. The rockers allow crossover movement from a neutral lever position to preselect a desired gate for reciprocal fore and aft travel of the ball follower to selected transmission shift positions.

Abstract: A disc brake is provided which comprises a self-contained wheel bearing including a casing with an axle structure extending into the casing and a bearing structure within the casing rotatably supporting the casing on the axle structure. The casing is connected to a wheel and forms the wheel hub. The axle structure is connected to a steering knuckle which has brake cylinder structure thereon. A brake plate having brake piston structure operatively engages the brake cylinder structure. Brake pads are provided in operative relationship to a brake disc which is slidably mounted on the bearing casing.

Abstract: A steering knuckle is provided which has a unitary sheet metal construction. A steering arm is integral with the steering knuckle. Brake cylinder structure adapted to operatively receive brake piston structure is carried by and extends outwardly from the steering knuckle.
