摘要

The functional component (1, 2, 3) housing is made from two assembled shells (4, 5), at least one of which has an inner wall (7) forming supports (8, 9, 10, 12, 13) and apertures (11) providing access for maintenance or fixings, and an outer protective wall (6). At least one of the two shells, which is exposed to a hostile environment, is made from a more robust material than the other.
