verriegelungsvorrichtung for linearaktuatoren

摘要

Locking device for linear actuators, in particular for fluid actuated adjusting devices, with a to form a seat (30) axially displaceably mounted piston rod (10), the an axially extending hollow space (11), in the fixed in the axial direction of the distributed connection means (12) and in the piston rod (10) to the shape of the end devices (12) corresponding positive locking elements (22) to an expansion sleeve (20) are arranged radially displaceable, wherein the positive locking elements (22) an actuating means in the form of an axially displaceable clamping cone (40) which is assigned to the positive locking elements (22) is displaced radially, characterized in that, on the expansible sleeve (20) a to the clamping cone (40) of complementary counter cone (23) is formed, via which the positive locking elements (22) out of engagement with the shape of the end devices (12) are held.
