摘要： The invention relates to a fuel injection valve for internal combustion engines and a method for producing the same. The inventive valve comprises a valve base body (2). A piston-shaped and axially moveable valve element (12) is arranged in said base body and in a bore (21), against the force of at least one closing spring (27, 28). The valve element controls the opening of at least one injection channel (19) at the end facing the combustion chamber and can be moved in the axial direction by means of the fuel pressure onto a pressure shoulder (10) when an opening pressure is reached, whereby said shoulder is configured on the valve element (12). The at least one closing spring (27, 28) is arranged in spring chamber (30) against an initial tension. Said spring chamber is embodied in a valve holding body (1). The at least one closing spring (27, 28) rests on an adjustment pin (31, 31) and thereby faces away from the combustion chamber. The opening pressure which is detected by means of the initial tension pertaining to the at least one closing spring (27, 28) can be adjusted by displacing the adjustment pin (31, 32) in the axial direction using an adjustment tool (49) which can be introduced through an adjustment bore (52). The position of the adjustment pin (31, 32) in the spring chamber (30) is subsequently fixed by caulking (Fig.1).

摘要： The fuel injection valve has a valve body (2), containing a piston valve element (12), displaced axially against at least one closure spring (27,28), within a valve bore (21), for controlling at least one fuel injection channel (19), in response to the fuel pressure acting against a pressure shoulder (10) of the valve element. The closure spring is contained in a spring space (30) and acted on by a setting bolt (31,32), displaced axially for determining the opening pressure of the injection valve. An Independent claim for a manufacturing method for a fuel injection valve is also included.

摘要： Fuel injection valve for internal combustion engines with a valve-holding body (1), in which a piston-shaped valve member (12) is arranged, which can be moved axially against the force of at least one closing spring (27,28) and, over part of its length, is guided in a hole (21) and which, at its combustion-chamber end, controls the opening of at least one injection passage (19), and with a spring space (30), which accommodates the at least one closing spring (27,28) and is formed in the valve-holding body (1) further away from the combustion chamber than the guided portion of the valve member (12). The valve member (12) being acted upon by the at least one closing spring (27,28), which is in each case supported at the opposite end from the combustion chamber by a piston-shaped adjusting stud (31,32), and with a pressure shoulder (10), which is formed on the valve member (12). At least one adjusting hole (52), which is formed as a through-hole in the wall of the spring space (30) and through which an adjusting tool (49) that can be used to adjust the axial position of the adjusting stud (31,32) can be introduced. The method for the production of a fuel injection valve, in which, before being fixed the adjusting studs (31,32) are adjusted by means of an adjusting tool (49) until the desired opening pressure of the valve member (12) has been achieved by means of the preloading force, obtained by displacement of the adjusting stud (31,32), of the closing spring (27,28) in contact there.

摘要： The spring chamber (30) in the valve retaining body (10) is filled with leaked oil, which when a predetermined level is exceeded, is diverted into a return line (70) in the valve retaining body. The leaked oil is fed to the spring chamber through an annular gap between the valve stem and its bore (25). The leaked oil is diverted into the return line through an annular space (41) provided in the cover (40).

摘要： The valve member (5) works in conjunction with a valve seat surface (9) on the valve body (1) for control of an injection cross-section. At least one valve string (37) acts on the valve member and is inserted in a spring space (35) in a valve holding body (21) tensioned axially with the valve body. The spring space at its end remote from the combustion chamber is closed by a cover (43). The cover is fixed by means of a border connection on the valve holding body. Between the cover and the valve holding body having the spring space a sealing ring (62) is fitted. The cover is cap-shaped and with its inner peripheral surface encloses around the upper end of the cylindrical valve holding body turned away from the combustion chamber. At the open end of the cover, a ring bulge (64) is provided at the outer cover surface of the cover.
