Abstract (en)

[origin: WO2016075118A1] The invention relates to an electromagnetic actuator (2) including a magnetic housing (20), a coil (22) that is rigidly connected to the housing and is capable of being connected to an electric circuit, a magnetic core (26) that is arranged in the coil and can move along a central axis (X2) defined by the coil and according to the strength of the current flowing in the coil, and a shunt (28) that is arranged in the coil and includes a magnetocaloric material (29) the magnetisation of which is temperature-dependent. The shunt is arranged in the coil along the central axis along a length (L) so as to create an air gap (E) between the shunt and the magnetic core. The actuator further includes means (31) for attaching the shunt to the housing that are designed to adjust said length.
