An actuation force can be transmitted to the valve element (14) by the armature pin (8). The invention is characterized in that the armature pin (8) is partly introduced into a depression (24) of the magnet armature (10), and the armature pin (8) and the magnet armature (10) are connected together in a contact region (48) in a force-fitting manner by means of an interference fit (20). The armature pin (8) has a changing outer diameter (47), in particular a continuously changing outer diameter, along the contact region (48).

Abstract: The invention relates to an electromagnetically actuatable inlet valve (24) for a high-pressure pump, in particular of a fuel-injection system. The inlet valve (24) has a valve member (34) which can be moved between an open position and a closed position. Provided is an electromagnetic actuator (60), by means of which the valve member (34) can be moved, wherein the electromagnetic actuator (60) has an armature (68) which acts at least indirectly on the valve member (34), a solenoid coil (64) which surrounds the armature (68), and a magnetic core (66), against which the armature (68) comes to rest, at least indirectly, when current is applied to the solenoid coil (64). The armature (68) is displaceably guided in a carrier element (78) and the carrier element (78) and the magnetic core (66) are interconnected and surrounded by a housing (69, 70, 71). The region of the connection (90) between the carrier element (78) and the magnetic core (68) is arranged in an inner chamber (91) of the housing (69, 70, 71).

Abstract: The invention relates to a solenoid valve having an actuator body (17), in which a magnet coil (15) that interacts with a magnet core (16) is arranged and which interacts with an armature (14) that can be moved relative to the magnet core between two end positions and is acted upon by the spring force of an armature spring (13) in a movement direction pointing away from the magnet core (16). The magnet core and the armature have stop surfaces (18a, 18b) which are interrupted by a recess (29) that receives the armature spring. According to the invention, a solenoid valve is provided which is improved with respect to the function of the solenoid valve and the stress on the stop surfaces (18a, 18b) that causes wear. This is achieved in that the magnet core (16) and/or the armature (14) have/has a design (30, 31), in particular a spherical or toroidal design, which reduces the stress on the edges in the region of the stop surfaces (18a, 18b).
