An electromagnetic linear actuator having a stationary annular assembly with a magnetic outer shell and a magnetic inner core. Monostable or bistable control components may be mounted interchangeably between the outer shell and inner core. An assembly which is moveable in the axis of the annular assembly includes two magnetic plates which face the extremities of the annular assembly and a rod which is mounted so that it can slide inside the core. The first core is made of a material chosen for its frictional characteristics. The actuator may be used to control the valve of a regulator in the fuel supply circuit of a satellite engine.
