In order to reduce the friction of a dry-running solenoid valve (1) with a valve housing (2), in which an electric coil (3) and a magnet armature (5) are arranged, and with a valve element (8) which can be actuated by the magnet armature (5) in an axial actuating direction for opening and closing the solenoid valve (1), in which the coil (3) generates a magnetic flux which, when the solenoid valve (1) is actuated, flows via a magnetically conductive valve housing outer wall (2c) of the valve housing (2) to the magnet armature (5), it is provided according to the invention that a magnetically conductive flux element (12) be provided in the valve housing (2) and introduce at least 80%, preferably at least 90%, and particularly preferably 100%, of the magnetic flux flowing over the valve housing outer wall (2c) into an armature end face (5B), facing the coil (3), of the magnet armature (5).

In order to provide a solenoid valve (1) with a valve housing (2), in which an electric coil (3) and a magnet armature (5) are arranged, and with a valve element (8) which can be actuated by the magnet armature (5) in an axial actuation direction for opening and closing the solenoid valve (1), wherein a valve lift of the valve element (8) can be limited in a simple manner, it is provided according to the invention that the coil (3) be arranged on a coil carrier (4), wherein an end section (4a), axially facing the magnet armature (5), of the coil carrier (4) is designed as an end stop for the magnet armature (5) in order to limit an axial movement of the magnet armature (5), and that the coil carrier (4) be formed from a plastic, wherein the coil (3) is at least partially integrated into the coil carrier (4).

Systems and methods for supplying lubricating oil to a high-pressure fuel pump of an engine fuel system. In one embodiment, a system may include a plurality of channels routing lubricating oil to a gear system and drive shaft of a pump without flowing an entire volume of the lubricating oil through a cavity of the drive shaft.

An injector component of an injector for introducing a fluid is described as including a base body, a coating on at least one first end face of the base body, the coating having a maximum, which lies on an outer half of the base body, and an outer lateral surface of the base body does not have any coating.

A valve including a magnet actuator (22) which has a magnet coil (6), a magnet armature (10) that moves in a stroke-like manner, and a pole core (20), wherein the magnet armature (10) and the pole core (20) together limit a working air gap (28), and the magnet armature (10) can at least indirectly contact the pole core (20), wherein the valve also has a valve element (14) which can be moved between an open position and a closed position, and which is at least indirectly in mechanical contact with the magnet armature (10). A separate magnet armature insert (8) arranged in the magnet armature (10) and/or a separate pole core insert (24) arranged in the pole core (20) is provided in the contact area of the magnet armature (10) on the pole core (20), in order to achieve a separation of the mechanical and magnetic forces.

An injector component of an injector for introducing a fluid is described as including a base body, a coating on at least one first end face of the base body, the coating having a maximum, which lies on an outer half of the base body, and an outer lateral surface of the base body does not have any coating.

A valve is provided, in particular an injection valve, having a valve seat and a valve needle which extends along a closing direction for the most part, the valve seat having a valve-seat surface, and a valve-closing element is mounted on an end of the valve needle facing the valve seat, the valve-closing element being able to be moved between an open position and a closed position, and the valve-closing element together with the valve-seat surface forming a sealing seat in the closed position, the valve-closing element having a greater core hardness and/or surface hardness than the valve-seat surface.

The present invention relates to a seat plate for an injector, comprising: a planar main body having a first flat side and a second flat side; a passage, which extends through the planar main body from the first flat side to the second flat side; and an indentation region in the first flat side, which indentation region surrounds an opening of the passage.
