Actuator for use in e.g. motor vehicle area, has housing partially enclosing rigid guideway, in which actuating unit is inserted or engaged, where actuating unit is formed in longitudinal extension in dimensionally-stable manner

摘要

The actuator has a housing (1) and an actuating unit formed movably relative to the housing, where the unit is wire-like, longitudinally designed. The housing partially encloses a rigid guideway (2), in which the actuating unit is inserted or engaged. The actuating unit is formed in a longitudinal extension in a dimensionally-stable manner, so that an actuating force is formed between the unit and housing in a longitudinal direction and against the direction of the unit. An energy unit is provided to supply or eliminate electrical, magnetic and/or thermal energy for producing the force.
