Abstract
Proportional electromagnetic actuator comprising: a magnetic casing; an electromagnetic plunger movable relative to the casing and having a first axial half; a first radial gap and a second radial gap which are each formed radially between the plunger and the casing, and which are positioned axially at the first axial half of the plunger. These gaps (26; 28) are formed by concentric annular chamfers (32; 34). A three-way valve for turbojet oil, which is actuated by an electromagnetic actuator with double chamfered gaps.
