Abstract

The invention relates to an electromagnetic linear actuator (10) for moving a rod (300) along an axial direction (A) relative to a support structure (600). The electromagnetic actuator comprises an exciting coil (400) wound around a circumferential direction (C) perpendicular to the axial direction (A); a fixed core (500) located at a first axial end of the coil (400) and fixed to the support structure (600); a and rod-moving arrangement comprising a rod-moving core (100) arranged at a second axial end of the coil (400) and for attaching to the rod (300). The rod-moving core (100) is moving between an open position when the coil (400) is not energized and a closed position when the coil (400) is energized. The open position and the closed position are spaced apart in the axial direction (A) by a rod-moving distance (d_rod). The electromagnetic actuator comprises further a shock-absorbing arrangement comprising a shock-absorbing core (200) disposed between the fixed core (500) and the rod-moving core (100). The shock-absorbing core (200) is moving between a stop position, in which the shock-absorbing core (200) is retained by a retaining force for blocking the rod-moving core (100) to move in the closed position when the coil (400) is not energized and a release position in which the shock-absorbing core (200) enables the rod-moving core (100) to move to the closed position when the coil (400) is energized, the stop position and the release position being spaced apart in the axial direction (A) by a shock-absorbing distance (d_shock) The shock-absorbing distance (d_shock) is less than or equal to the rod-moving distance (d_rod).
