摘要： A fuel injection valve for internal combustion engines with a valve body (1) at the combustion chamber side of which there is an annular pressure chamber (25) connected to a supply channel (5) and bounded by an elastic valve member (11) which bears under its own tension via a valve sealing surface (27) on a fixed valve seat (29), from which it can be lifted by pressure in the pressure chamber (25). The aperture cross-section thereby controlled is downstream of at least one injection aperture (31) into the combustion chamber of the internal combustion engine. Here, the centre of the elastic valve member (11), which takes the form of a diaphragm, is secured against the valve body (1) and its radially outwardly directed edge region forms the elastic sealing surface (27) which can be elastically raised from the valve seat (29).

摘要： The invention relates to a fuel injection valve comprising a valve body (1) and a bore (3) configured as a blind bore, whose bottom area faces the combustion chamber. A conical valve seat (9) is formed on said bottom area and accommodates at least one injection opening (11). A piston-shaped valve member (5) is disposed in the bore (3). Said valve member can be displaced in the longitudinal direction against a closing force and is provided with a valve tip (7) which rests against the valve seat (9) when the valve member (5) is in the closed position. A first cone surface (30) and a second cone surface (32) are configured on the valve member tip (7), said second surface being disposed so as to face the combustion chamber relative to the first cone surface. The cone angle ( alpha ) of the first cone surface (30) is smaller than the cone angle ( gamma ) of the valve seat (9), which in turn is smaller than the cone angle ( beta ) of the second cone surface (32). An annular groove (35) is formed between the first (30) and the second cone surface (32), and an additional continuous annular groove (42) that at least partially overlaps the injection openings (11) in the closed position of the valve member (5) is formed on the second cone surface (32), thereby evenly providing all injection openings (11) with fuel even if the valve member (5) is misaligned.

摘要： A fuel injection nozzle for internal combustion engines has a holder (11) with a projecting fixed nozzle needle (15) with the end section (17) bearing a valve cone (18) of which an annular valve diaphragm (31) acts in the manner of a valve. The outer edge section (41) of the valve diaphragm (31) is clamped against the holder (11) by a union nut (32), whereby the edge (49) surrounding the aperture (39) is spring-loaded against the valve cone (18). In order to keep the stresses during the bending-generated movement of the valve diaphragm (31) low over their entire range, the valve diaphragm (31) has a bulge (40) against the direction of movement. The bulge (40) preferably consists of an annular region (42) with a steep inclination (α) adjacent the clamped outer edge section (41) and an annular region (43) extending to the aperture (39) with a shallow inclination (β). The bulge (40) may also be cone or dome shaped. To limit the travel of the valve diaphragm (31) there is a travel abutment disc (33) which is clamped to the holder (11) together with the valve diaphragm (31) by the union nut (32). The shape of the injection jet is influenced by the shape of the end section (17) of the nozzle needle (15) and the through aperture (51) in the travel abutment disc (33).
