Electromagnetically actuated valve, having • a valve body in which an inlet and an outlet are formed, • a valve seat which surrounds a main nozzle and which is arranged in the valve body between the inlet and the outlet in terms of flow, • an armature which is arranged in the valve body for movement merely in a linear manner along a spatial direction, • a coil which, when current flows through, generates a magnetic field for movement of the armature along the spatial direction, • a preloading device, • a sealing nipple in which a pilot-control bore is arranged, • a nipple guide in which the sealing nipple is accommodated and which is arranged in the valve body for movement merely in a linear manner along the spatial direction between a closed position and an open position, wherein nipple guide and armature are movable relative to one another to a limited extent, • wherein, in the closed position, the sealing nipple closes off the main nozzle in such a way that only the pilot-control bore connects inlet and outlet and, in the open position, the sealing nipple is spaced apart from the valve seat, • wherein the preloading device exerts a force on the armature that preloads the latter into a rest position, in which rest position the armature transmits the force to the sealing nipple, wherein the force pushes the sealing nipple into the closed position and the armature closes off the pilot-control bore, • wherein the armature has a driving element which, with movement of the armature from the rest position into an intermediate position, comes into engagement with the nipple guide after opening of the pilot-control bore, and • wherein, with further movement of the armature from the intermediate position, the driving element pulls the nipple guide from the closed position into the open position, characterized in that • the main nozzle is formed in a tube which forms the valve seat at a longitudinal end and on whose outer surface the nipple guide is arranged in a linearly movable manner. • a valve body in which an inlet and an outlet are formed, • a valve seat which surrounds a main nozzle and which is arranged in the valve body between the inlet and the outlet in terms of flow, • an armature which is arranged in the valve body for movement merely in a linear manner along a spatial direction, • a coil which, when current flows through, generates a magnetic field for movement of the armature along the spatial direction, • a preloading device, • a sealing nipple in which a pilot-control bore is arranged, • a nipple guide in which the sealing nipple is accommodated and which is arranged in the valve body for movement merely in a linear manner along the spatial direction between a closed position and an open position, wherein nipple guide and armature are movable relative to one another to a limited extent, • wherein, in the closed position, the sealing nipple closes off the main nozzle in such a way that only the pilot-control bore connects inlet and outlet and, in the open position, the sealing nipple is spaced apart from the valve seat, • wherein the preloading device exerts a force on the armature that preloads the latter into a rest position, in which rest position the armature transmits the force to the sealing nipple, wherein the force pushes the sealing nipple into the closed position and the armature closes off the pilot-control bore, • wherein the armature has a driving element which, with movement of the armature from the rest position into an intermediate position, comes into engagement with the nipple guide after opening of the pilot-control bore, and • wherein, with further movement of the armature from the intermediate position, the driving element pulls the nipple guide from the closed position into the open position, characterized in that • the main nozzle is formed in a tube which forms the valve seat at a longitudinal end and on whose outer surface the nipple guide is arranged in a linearly movable manner.
