Abstract: A fuel injection nozzle in which the needle valve has been improved so that all similarly constructed nozzles will exhibit exactly the same flow cross section with a fully opened valve, and so that, with a constant injection pressure, the fuel quantity injected will not vary between the various nozzles serving the engine. The needle valve is provided with a cyclindrical section, which together with an edge region of the nozzle body defines the narrowest flow cross section obtainable with a spray-forming portion of the needle valve at a fully opened position of the needle valve.

Abstract: The subject apparatus includes an egg receiver, an egg weighing device having an egg carrier, a conveyor belt for transporting a weighed egg, an ejector for ejecting weighed eggs from the conveyor and a collector of the weighed eggs. The improvement has an electronic weighing device having a vertically moveable lifting frame with a receiver cooperating with the egg-carrier. The lifting frame includes an interconnected lifting arm synchronously moveable with a conveyor horizontally moveable to and fro and a linking element along the collector having a vacuum control suction cup controlled by a pair of bellows cooperating synchronously with the egg carrier to receive an egg.
