摘要： The invention proposes 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. An electromagnetic actuator (60) is provided, 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 magnet 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 magnet coil (64), wherein the armature (68) is movably guided in a carrier element (78), and the carrier element (78) and the magnetic core (66) are interconnected. The carrier element (78) and the magnetic core (66) are interconnected by a sleeve-shaped connection element (90) which is integrally bonded in a first connection region (92) to the carrier element (78) and/or the magnetic core (66), and interlockingly engages the carrier element and/or the magnetic core in a second connection region (94) offset relative to the first connection region (92) in the direction of the longitudinal axis (91) of the connection element (90).

摘要： The invention relates to an electromagnetically actuatable expansion valve for a refrigerant, said valve comprising a valve body (1) with a bore (2), in which a substantially cylindrical valve slide (3) is arranged such that it can be displaced axially in order to connect a supply line (4) to a discharge line (5). According to the invention, the discharge line (5) is formed by a hollow cylinder (6) which is inserted in the bore (2) and the end of which facing the valve slide (3) forms a valve seat (7) that can be closed by means of a separate valve closure element (8).
