TEMPERATURE-SENSITIVE ACTUATING APPARATUS FOR A SERVO APPARATUS

摘要

A temperature-sensitive actuating apparatus (1) for a servo-apparatus (2) contains in a housing (6) of the servo-apparatus (2) an actuating element (5) which has a length changing with temperature and is of a metal having a shape memory for a servo-element (7). The actuating apparatus also comprises a heating apparatus (18). To give more latitude to the construction and arrangement for the actuating apparatus (1) and the heating apparatus (18), the actuating apparatus (1) comprises a connecting member (3) attachable to the exterior of the housing (6) of the servo-apparatus (2) and containing the heating apparatus (18). When the connecting member (3) is attached, the larger part of the actuating element (5) is introduced into the connecting member (3) out of the servo-apparatus (2) through a wall (10) of the housing (6) of the servo-apparatus (2) in a capillary tube (4) substantially thermally insulated from the interior of the housing (6) of the servo-apparatus (2).
