摘要

Abstract invention patent: "sealing device in the parade to system of passive joints of a motor pump group tree primary school".The present invention relates to a device for tightness in the parade passive (20, 40) to the primary motor pump group which comprises a series of bimetallic thermal devices (21,41) which have a first position, said cold position, when the temperature of such devices is less than the said bimetal temperature limit, and a second position, that position hot.When the temperature of the bimetal device is higher than the temperature limit; a sealing ring (23) which presents a position when the bimetal thermal activated devices (21.41) are in its hot position and presents a inactive position when the devices are in their position cold thermal bimetal; means of locking / unlocking (25) adapted to stopThe said sealing ring (23) in its inactive position when the bimetal thermal devices (21,41) are in position and for releasing the cold said sealing ring (23) when the bimetal thermal devices (21,41) are in its hot position; elastic means (24) adapted to force said sealing ring (23) in the activated position when the locking / unlocking means (25) are destravados.
