• an interceptor member,
• an actuating means,
• a drive unit operated by a power supply, and
• a guiding arrangement, said guiding arrangement being arranged to guide said interceptor member between a first position and a second end position, said actuating means being arranged to displace said interceptor member in a movement between said first and second positions in relation to said housing member by being driven by said drive unit, and said housing member comprising a front plate and a rear plate enclosing said interceptor member in said first position and partially enclosing said interceptor member in said second position, wherein said guiding arrangement has a first guiding member and a second guiding member which are arranged to interact with each other to provide a parallel movement of said interceptor member in relation to said housing member, said first guiding member being a torque transferring, rotatable element having a base body arranged to extend transverse to the direction of displacement of said interceptor member and having at least two fixedly attached toothed wheels, said second guiding member comprising at least two toothed guiding surfaces fixedly arranged to said interceptor member interacting with said toothed wheels, characterized in that said first guiding member is movably arranged in between one plate of said housing member and said second guiding member, to follow the movement of said interceptor member.
