摘要： An injection valve for fuel injection devices for internal combustion engines which serves to inject fuel into the intake pipe. The injection valve consists of a valve body with a valve seat cooperating with the sealing part of a valve needle. The valve needle is guided by guide sections in a guide bore of the valve body. The guide section immediately adjoining the sealing part simultaneously serves as a metering section for metering the fuel. For this purpose axially extending surfaces are disposed on the metering section, which form throttling metering openings together with the guide bore. By metering the fuel upstream from the valve seat, impairment of the fuel metering because of deposits formed by reaction of harmful materials from the intake pipe is avoided.

摘要： An injection valve for preparing fuel injected into an intake tube of an internal combustion engine and an injection valve for performing the method are proposed. The injection valve includes a movable valve element, which cooperates with a fixed valve seat, downstream of which the fuel reaches fuel guide bores inclined relative to the valve axis and this fuel discharges into a preparation bore at a distance (a) on the bottom from the wall. The fuel flowing via the fuel guide bores at first exits freely from the discharge openings of the fuel guide bores into the preparation bore and subsequently arrives at the wall of the preparation bore, from where it flows in the form of a film, distributed over the wall, toward the open end of the preparation bore and is ejected into the aspirated air of the internal combustion engine.

摘要： A fuel injection system for internal combustion engines is proposed which serves the purpose of fuel injection into the air intake tube of the engine. The fuel injection system includes a fuel injection valve, which is supported upstream of a throttle valve in a holder body disposed coaxially in the air intake tube. A fuel supply line leads to the fuel injection valve, extending in a downwardly directed manner toward the fuel injection valve and away from a deaeration chamber. A fuel return line leads away from the fuel injection valve, extending in an upwardly inclined direction to discharge into the regulating chamber, disposed at a higher level, of a pressure regulating valve. A fuel feed line originating at a fuel supply pump terminates in an upwardly directed manner into the dearation chamber, which communicates via a dearation nozzle with the regulating chamber, so that vapor bubbles can escape upstream of the injection valve into the return side of the injection valve.

摘要： A fuel injection valve is proposed for fuel injection systems of internal combustion engines, which serves to supply fuel into the intake tube of the engine. The injection valve includes a movable valve element which cooperates with a fixed valve seat, downstream of which are provided horizontal fuel guidance bores which discharge tangentially into a spin chamber. The spin chamber is disposed so that it widens conically in the flow direction. The fuel guidance bores simultaneously serve as metering bores. The spin chamber causes an axial speed component to be imparted to the fuel entering via the fuel guidance bores. As a result, the dwell time of the metered fuel within the spin chamber is short, and even in the case of quite short injection pulses, the fuel is still sufficiently well prepared.

摘要： An electromagnetically actuatable valve, especially an injection valve for fuel injection systems which supply internal combustion engines with fuel, is proposed in which the fuel injection valve encompasses a valve chamber and a core upon which a magnetic coil is mounted by means of a carrier body. Fuel supply openings discharge into a flow passage provided around the magnetic coil. Vapor bubbles dissolved in the fuel may be flushed out of the flow passage via a first restriction into fuel return openings which communicate with a fuel return line. On the other hand, the fuel may flow from the flow passage into the collecting chamber which houses a valve component and a valve seat. Vapor bubbles which may appear near the valve component may be flushed out via a second restriction which is provided in the interior of a core to reach the fuel return openings. Thus, disturbances with fuel injection, especially during the "hot start" of the internal combustion engine, are avoided.

摘要： An electromagnetically actuatable valve which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing as well as a magnetic coil with poles serving as the core, with which an armature cooperates, which is connected to a valve element the sealing element of which cooperates with a valve seat in a valve seat body. The valve element protrudes without contact through a throttle bore in the valve seat body with a throttling element and is held in a sealing manner on the valve seat by the armature when the magnetic coil is excited. When the magnetic coil is not excited, the valve element is moved by the pressure forces of the fluid in the opening direction of the valve and is centered by the fluid flow.

摘要： A flow rate meter is proposed which serves to ascertain the quantity of a flowing medium particularly the quantity of air aspirated by an internal combustion engine via an air intake tube. The flow rate meter includes a measuring device pivotable in a flow channel about a support shaft downstream of which measuring device the flow channel is suddenly enlarged at several zones in order to reduce the measurement error at a maximal flow rate of the medium.

摘要： A fuel injection valve which serves to inject fuel into the intake tube of internal combustion engines. The fuel injection valve includes a valve seat disposed in a valve housing, downstream of which valve seat a preparation bore is provided in a nozzle body, which terminates in the fuel flow direction at a sharp-edged nozzle body end embodied by a first conical zone. The first conical zone protrudes into a cylindrical guide conduit of a front attachment. The cylindrical guide conduit discharges via a first guide conduit end into a conically widening guide conduit, which leads via a second guide conduit end into the intake tube of an internal combustion engine.
