Abstract An outer valve jacket having an open end accommodates an electromagnetic actuator inwards of the open end. The electromagnetic actuator comprises a solenoid-energized iron core and an armature reciprocable towards and away from the open end, the latter enclosing at least part of a valve housing and a valve needle in the valve housing. The valve needle is coaxially reciprocably connected with the armature and axially movable in the valve housing between a valve opening and a valve closing position. The valve housing is secured in the open end of the outer jacket in such a way that a circumferential portion of the jacket is radially inwardly upset and accommodated in at least one circumferential groove in the valve housing, the latter having an outer diameter substantially equal to the inner diameter of the outer jacket.
An electromagnetically actuable injection valve, particularly for internal combustion engines, comprising an outer jacket having an open end and a thin wall in the region of said open end; an electromagnetic actuator inwards of said open end and comprising an armature reciprocable towards and away from said open end; a valve housing in said outer jacket and extending at least in part inwards of said open end; a valve member in said housing and reciprocable with said armature between a valve opening and a valve closing position; and connecting means connecting said valve housing with said outer jacket and comprising two circumferentially parallel grooves provided in an outer circumferential surface of the valve housing and two parallel radially inwardly upset sections of said outer jacket in the region of said open end and accommodated in said two parallel grooves.
