摘要: 888,138. Low-temperature seal. ROLLSROYCE Ltd. Oct. 27, 1960 [Nov. 3, 1959], No. 37273/59. Classes 122 (1), (3) and (5). [Also in Group XXXII] A sealing device for use at low temperatures comprises a resilient V-section member 10, e.g. of rubber or P.T.F.E., provided between its limbs with bimetallic spring 13 arranged to urge the 10 towards portion force which increases decreasing temperature. The is made from length strip material formed plurality integral V-shaped portions 14, being bent along adjacent longitudinal centre line form component 18 contact 11, 12 has coefficient expansion greater than that 17 so that, as temperature decreases, bows exerts on lips.
