Compression unit for e.g. cable and/or pipe passage, has bolt to press rectangular and triangular parts for moving along contact surfaces against each other, where movement is controlled by cooperating grooves and parts

摘要

The unit has two rectangular compression parts (1), and two triangular compression parts (2, 3) inserted in triangular areas, which are formed between the rectangular compression parts. Inclined contact surfaces are formed between the rectangular and triangular compression parts, such that the unit is controlled. The distance between the rectangular compression parts is increased or decreased. A bolt is provided to press the parts (1, 2, 3) for moving along the surfaces against each other. The movement is controlled by cooperating grooves and parts.
