Embodiment Construction

[0022] exist figure 1 The gas metering valve 1 according to the invention shown in , has a housing 2 in which a gas channel 13 is arranged, through which the metered fuel gas flows. Fuel gas passes through the gas inlet 12 into the gas metering valve 1, flows through the gas channel 13 and through the gas outlet 14 into the intake duct 15 leading to the dual fuel engine 17 ( image 3 ) of the combustion chamber 16. In the region of the gas outlet 14 there is a valve seat 5 which has a plurality of circular, concentric slits 8 which can be selectively closed and opened by the closing body 6 . The closing body 6 has a corresponding number of concentric rings 25 which are connected to one another by radial segments distributed around the circumference and which, for closing the valve, are pressed against the concentric slits 8 of the valve seat 5 and seal against said slits. .

Abstract

The invention relates to a gas metering valve (1) for a dual fuel engine (17), which has a displaceable closing body (6) which, in a position of resting against a valve seat (5), closes the gas metering valve (1) and, in a position of being lifted off from the valve seat (5), opens the gas metering valve (1). The gas metering valve (1) is actuatable in a gas operating mode, in which the gas metering valve (1) meters combustion gas via a gas channel (13) into an intake manifold (15) of the dual fuel engine (17), and in a liquid fuel operating mode, in which the gas metering valve (1) remains sealingly closed against the pressure prevalent in the intake manifold (15). The valve seat (5) is movably situated along a valve seat guide (4), the valve seat (5), owing to the combustion gas pressure in the gas channel (13), in the gas operating mode being pressed away from the closing body (6) against a stop (20) in the gas metering valve (1) and is kept in its operating position, and the valve seat (5) in the liquid fuel operating mode being sealingly pressed by the pressure from the intake manifold (15) against the closing body (6).

Description

technical field [0001] The invention relates to a gas metering valve for a dual-fuel engine, which has a displaceable blocking body, which closes the gas metering valve in a position against a valve seat and is activated from The gas metering valve is opened in the raised position of the valve seat, wherein the gas metering valve can be operated in a gas operating mode and in a liquid fuel operating mode, in which the gas metering valve Fuel gas is dosed via the gas channel into the intake manifold of the dual-fuel engine, and in the liquid fuel operating mode the gas metering valve remains tightly closed against the pressure prevailing in the intake manifold. Background technique [0002] Gas metering valves of this type are used, for example, as intake manifold boosters for large gas engines, which can be operated in two operating modes, i.e. on the one hand with fuel gas (gas operating mode) And on the other hand it operates on liquid fuel (liquid fuel operating mode). ...
