HOSE CLAMP WITH TENSION MAINTAINING LOOP

摘要

A hose clamp or clip (10) is typically adapted to secure a flexible hose of an automotive cooling system to say a water pump or radiator inlet/outlet port. The clamp (10) comprises a band (11) typically fabricated from stainless steel or zinc plated carbon steel. Attached to the overlapping portion of the band (11) is a screw housing (12) within which a screw (13) is situated. The band (11) comprises a deviation (14) in the form of a protruding loop. Where the band (11) is fabricated from sufficiently resilient material, deviation (14) provides a sufficient degree of resilience to allow expansion/contraction of the band (11). However, should band (11) not be formed of sufficiently resilient material, an additional spring (15) can be provided. Spring (15), typically fabricated from spring steel, is "C" shaped and comprises a pair of opposed edges (20) which press against the band (11) at opposing identations (18). The invention is particularly advantageous in applications where the clamped fittings undergo thermal expansion/contraction.
