Linear movement actuator for e.g. air conditioning system, has position sensor for detecting stroke movement of operating unit in control position, where servo unit is controlled based on detected stroke movement of operating unit

摘要

The actuator has an operating unit (12) that is provided with a servo unit (22), where the operating unit is movable against an action of a spring unit (28) from a base position to a control position (31). A position sensor (33) is provided for detecting stroke movement of the operating unit in the control position, where the servo unit is controlled based on the detected stroke movement of the operating unit. The operating unit is retained in the base position by a force of the spring unit.
