摘要： The invention concerns a safety device (1) for an actuator comprising a connection means (2) allowing a connection to a releasable holding means (5). The connection means (2) is fixed via a sacrificing means (3) to a supporting means (4), and a resilient means (7) is acting between the supporting means (4) and a supporting portion (8). An extension means (9) is fixed to the supporting means (4) via the connection means (2). The sacrificing means (3) has a mechanical strength such that the sacrificing means (3) breaks when subjected to a force exceeding a predetermined force, such that the extension means is no longer fixed to the supporting means and that a re-connection of the supporting means (4) and the releasable holding means (5) is made impossible. The predetermined force is lower than the mechanical strength of the extension means (9) and the supporting means (4). A linear actuator (13) comprising the safety device (1) is also provided.

摘要： A device for changing a pitch of a blade of an impeller/propeller is disclosed. It comprises at least one linear actuator. A first bearing is mounted to a non rotary mechanical element with the first portion, and a second bearing is mounted to the second portion, allowing a relative axial movement between the first bearing and second bearing. The first bearing is mounted between a supporting structure of the rotor shaft and the non rotary mechanical element, allowing a relative rotation between the supporting structure and the at least one linear actuator. The second bearing is mounted between the second portion and a lever means having a rotary point at the supporting structure. When operating the at least one linear actuator, the second portion is moved axially, leading to an angular movement of the lever means causing a change of the pitch of a blade, and when operating the at least one linear actuator, a force is generated that acts upon the non rotary element, so that the rotor shaft is unaffected by the force. Also, a fan comprising the device is disclosed.

摘要： The invention concerns a valve actuator (1) comprising a housing (2) and a nut and screw arrangement. A first portion (5) of the nut and screw arrangement is operated by an electric motor (7), which is fixed to the housing (2). A means (8) is in contact with a second portion (6) of the nut and screw arrangement, and a resilient means (9) is acting between the means (8) and the housing (2). A relative rotation between the threaded nut (3) and the threaded screw (4) leads to a translation of the means (8) and an energizing or de-energizing of the resilient means (9). A locking means (10) locks the resilient means (9) in an energized state by locking the relative rotation of the nut and screw arrangement. When the locking means (10) are released, the resilient means (9), when de-energizing, acts on the means (8), leading to a translation of the means (8).

摘要： The invention refers to an influencing mechanism to be used in a stop valve and/or regulating valve, comprising a spring (3, 26) and a releasable holding means for controlling the movement of a spindle (1, 22), associated with the valve in a first end position, where the spring (3, 26) is in a compressed state. The releasable holding means is electro-mechanical and fluid-free, and is arranged to cause the spring to expand to an uncompressed state in a constrained, controlled manner, for causing the spindle (1, 22) to move in a controlled manner to a second end position, and alternatively to release the spring, when the spring is in its compressed state, for allowing the spring to expand in a non-constrained manner to an uncompressed state, thereby releasing kinetic energy stored in the spring in its compressed state for causing the spindle to move in an unconstrained manner to the second position.
