摘要： A power generating assembly including an internal combustion engine and a combustion gas supply connected to the internal combustion engine in order to supply combustion gas. The combustion gas supply has an at least double-walled line at least in the region of the internal combustion engine, the line having an inner line volume for combustion gas and an outer line volume. The outer line volume is fluidically connected to an inert gas supply. The power generating assembly also includes a combustion gas pressure adjusting device that adjusts a combustion gas pressure in the inner line volume, and an inert gas pressure adjusting device that adjusts an inert gas pressure in the outer line volume. The combustion gas pressure adjusting device and the inert gas pressure adjusting device select the inert gas pressure and the combustion gas pressure such that the inert gas pressure is higher than the combustion gas pressure.

摘要： A device for mixing a gaseous fuel into an oxygen-containing gas flow of a gas-powered internal combustion engine includes a housing component having an inlet that connects to a gaseous fuel supply conduit and a slit that opens into an intake pipe. The slit has a longitudinal extension that is oriented approximately perpendicular to the axial direction of the intake pipe. A valve body is movable relative to the housing component. An annular gap between the valve body and an outlet opening of the housing component has a cross-sectional area that varies in accordance with changes in the position of the valve body relative to the housing component. The annular gap determines the flow-through cross-section of a passageway between the inlet and the outlet. Furthermore, a gaseous fuel flow exiting from the slit is directed approximately perpendicular to the axial direction of the intake pipe.

摘要： A guide portion slidably receiving a movable core is constructed by a large-diameter portion, a middle-diameter portion, a first small-diameter portion, a magnetism blocking portion, and a second small-diameter portion. A ring portion, which has an outer diameter greater than that of a coil assembly provided radially outside of the guide portion, is provided radially outside of the middle-diameter portion. When the guide portion attached with the coil assembly is attached to a support member corresponding to a mating member, the guide portion is attached to the support member by applying a rotational torque of to the ring portion in an axial direction of the guide portion according to a tool without an interference between the tool and the coil assembly. Therefore, an electromagnetic valve device for a gaseous fuel can be readily attached to the support member.

摘要： An electromagnetic pressure regulating valve includes a valve body and that causes the valve body to move to adjust an opening degree of a valve passage, thereby regulating secondary pressure p2 to target pressure. The valve body is slidingly supported by a bearing member, and a diaphragm seal and a low-pressure sealing member respectively seal both sides of the bearing member. The diaphragm seal receives the secondary pressure p2 from a pressure return chamber, connected to a secondary port, to cause the valve body to move toward a closed position. A back pressure chamber connected to a primary port is formed by a seal rod inserted in the valve body, and a buffer chamber connected to the secondary port is formed in a housing. A high-pressure sealing member seals between the buffer chamber and the back pressure chamber.
