摘要： A method and apparatus for metering fuel to an engine wherein a continuous supply of fuel is provided by a pump (14) to a fixed capacity chamber (11) and gas under pressure is admitted periodically to said chamber to maintain in the chamber a pressure not greater than the fuel pressure, so that fuel will flow into the chamber as long as there is a pressure differential between the gas in the chamber and the fuel supply. A delivery port (20) in said chamber is open for substantially the duration of the period that gas is admitted to the chamber so that the fuel in the chamber at the time of admission of gas thereto, and fuel entering the chamber during the period of admission of gas, is delivered from the delivery port (20) to the engine. The pressure differential between the fuel supply and the gas in the chamber is controlled in accordance with the fuel demand of the engine to control the quantity of fuel delivered each cycle to the engine. A preferred form of each of a fuel referencing regulator (34), a fuel pressure regulator ( 16) and a metering and injection unit (25) are also disclosed.

摘要： An electromagnetic actuator, particularly for a valve for controlling the injection of fuel or fuel oil is described and comprises: a fixed permanent magnetic core, and an electrical control winding which is disposed in the magnetic field generated by the core and is movable relative to the core when an electrical current flows through the winding, in which the winding is intended to be connected to a movable member actuable by the device, in a manner such as to bring about movement of the movable member between a rest position and at least one operative position. The winding is also arranged to act on the movable member by exerting a resilient force which can hold the member in the rest position or return the member to the rest position.

摘要： A fuel injection nozzle for a combustion engine not only has a valve for alternately opening and closing the nozzle, but also has a part which undergoes alternating stroke movement, either longitudinally or transversely. The alternating stroke movement changes the opening angle of the nozzle opening. The alternating stroke movement is in a frequency range of approximately 5 to 20 kiloHertz.

摘要： An atomizing nozzle device comprises a housing in which an inner chamber is defined. Fluid is introduced into the chamber and is discharged therefrom through an orifice of a metallic screw cap of the device. Within the chamber a stem is arranged, which stem is connected to a closing head cooperating with the orifice through a rod. A spring acts on the stem for causing the head to close the orifice and consequently prevent the discharge of fluid from the device. A solenoid coil is provided and supplied with a current through a current path in which a switch contact is established through the cooperating closing head and the end cap. By the supply of an energizing current to the solenoid coil, the stem is caused to move causing the closing head to move relative to the orifice for opening the orifice and consequently discharging fluid from the nozzle device. By the movement of the closing head relative to the cap, the current supply to the solenoid coil is interrupted resulting in that the spring forces the closing head to close the orifice. Through the establishment and interruption of the current path to the solenoid coil, a self-controlled vibrating-type nozzle device is provided.
