摘要: An axially expanding spacer (10) has respective first and second spacer rings (11,12) with complementary helical ramped faces (16,17) and abutment faces (18,19). By relative rotation of the spacer rings (11,12), the height of the spacer (10), between annular faces (14,15) can be expanded or contracted. Compression springs (20) between the abutment faces (18,19) urge the spacer (10) to its “expanded” configuration.
