ABSTRACT:
The invention relates to a sliding regulator, having a sliding slot which is closed without leaks against dust, etc., even in the immediate surrounding of the sliding member. According to the invention, this is achieved by a rubbery-elastic sealing lip associated with the sliding slot, which consists of a string of aligned lamellae attached to each other so as to form a flexible barrier against penetration of unwanted matter. The lamellae barrier deforms as the sliding member slides through it, so that the interface between the two remains substantially constantly sealed.
