Abstract

An actuator unit (1) of a cam shifting system, which actuator unit is mountable on an internal combustion engine or a component thereof and has at least one actuator pin (5) for moving shifting cam units of the cam shifting system into different axial positions by means of at least one shift groove formed on the periphery of the shifting cam units and cooperating with the actuator pin (5). The actuator pins (5) are spring-loaded in a direction toward the shifting cam unit, operable by a solenoid unit, and slidably supported in a housing (2) of the actuator unit (1). The housing (2) of the actuator unit (1) is provided with at least one enlargement in each inner surface facing an actuator pin (5).
