An actuating device includes at least one magnetic drive () with a solenoid coil () accommodated in a housing (). The solenoid coil generates heat during operation affecting the performance of the device. The heat is dissipated at least partially into the environment as power loss via the housing (), is disclosed. For improved heat dissipation, parts () of the device are formed of at least one special plastic material, which has a thermal conductivity coefficient of 0.25 to 1.25 W/(m·K) or W/m/K (i.e., watts per meter per Kelvin).

Actuating device

A device has a sensor () for detecting a contamination in the form of metal particles in a fluid, and is at least partially encompassed by a partition wall (). Partition wall () is at least partially penetrated via a receiving opening () by the sensor device () arranged in its functional position and comprising its sensor () detecting the metal particles. The sensor () can be removed from the partition wall () into an inoperative functional position, in particular for maintenance or replacement purposes. The sensor () interacts with a closing device () such that upon removal of the sensor () to its inoperative functional position, the closing device () closes the receiving opening (). In the opposite direction, when the sensor () is brought into its functional position, this receiving opening () is released.

Sensor apparatus for metal particles in fluids

A pneumatic suspension system for a vehicle is provided comprising a mounting arrangement for mounting a portion of the vehicle on a chassis; the mounting arrangement including at least one pneumatic spring to be arranged and coupled between the portion of the vehicle and the vehicle chassis. A vehicle state control system is provided that provides a pressure set value in the pneumatic spring and a pressure controller is arranged to a valve device alternatively for pressurizing or depressurizing the each pneumatic spring. The valve device comprises at least a first valve having a valve outlet coupled to the spring terminal and a valve inlet communicatively coupled to the pressure terminal. A support structure () distinct from the sealing edge () is provided arranged to providing supporting contact to the sealing face to counteract deformations of the sealing face.

An electromagnet, in particular a switching magnet, has a field winding () located on a coil former (), and has a pole piece () forming a part of the magnetic return path. A pole core () and an axially movable magnetic piston () are provided within the coil former (). The pole piece () forms an aperture opening () for the magnet piston () on the area opposite the pole core (). The magnet piston () is borne for its movement in its guide in the pole core (). The pole piece () has a flange part () at least partially engaged over the coil former () at its axial end, and has a bush part () which extends axially from it. Within the coil former (), the pole piece forms a hollow cylinder engaged over a longitudinal section of the magnet piston (). Between the inner wall of the hollow cylinder and the circumference of the magnet piston (), a parasitic air gap () is formed.

Electromagnet

A safety apparatus for avoiding a possible fire risk in an operating magnet supplied with electric current has at least one coil former () arranged in a housing (). A coil winding () is fitted on the coil former and has an operating part () at least partially guided in the coil former (). At least parts of the operating magnet are equipped with active and/or passive safety mechanisms of the apparatus to effectively counteract the risk of fire. The safety mechanisms are no longer arranged remote from the actual event, for example in the form of a fuse in the electrical supply circuit, but rather are directly at the location of the event where the possible fire or scorching situation can directly occur.
