    摘要: The pressure relief valve has a spring pressure-loaded diaphragm closing body (13), which in the closed position sealingly engages on a centrally positioned valve seating surface (10) surrounding a first valve opening (8). Its spring pressure loading takes place by means of a counterpressure body (13) positioned centrally over it. The valve seating surface (10) is surrounded by a channel-like valve chamber (11) in the valve housing body (2) and on which is provided on the overpressure side at least one second valve opening (9). To be able to dissipate high overpressures, the counterpressure body (30) is surrounded by a diaphragm support ring (17) held on the valve housing (6) and which has a circumferential recess (19), whose depth measured perpendicular to the diaphragm closing body (13) determines the maximum deflection of said body (13), so that when the valve is completely opened the diaphragm closing body (13) is supported in an area between the valve seating surface (10) and its outer edge.

    摘要: A mixture delivery device for introducing a reducing agent into an exhaust gas system of an internal combustion engine in which, a urea-water solution is introduced into a region of the exhaust gas system, upstream of a catalytic converter, through the introduction of compressed air, in order to bring about the reduction of nitrogen oxides in the exhaust gas of the internal combustion engine. The mixture delivery device includes a mixture carrying line, with a first section that extends laterally to the exhaust gas flow and a second section that extends concentrically to a longitudinal axis of the exhaust gas system. The mixture carrying line is inserted into the exhaust gas system, wherein the urea-water solution is injected in the form of a cone into the exhaust gas upstream of the catalytic converter via blow-out openings embodied radially in the second section. The mixture delivery device is particularly suited for delivering a urea-water solution upstream of the catalytic converter in the exhaust gas system of a mixture compressing, spontaneously igniting internal combustion engine.
