Embodiment Construction

[0034] figure 1 An exemplary ventilation duct R is shown having a circular cross-section and having an actuator 1 mounted thereon and a device VS of the invention. RA denotes the outside of the duct, and HR denotes the hollow space formed in the ventilation duct R for transporting, in particular, air.

[0035]The actuator 1 shown has an actuation connection 2 cooperating with a flap arranged in a ventilation duct R (not shown in this figure) for setting the air flow. The actuator 1 also comprises a housing 3 having a bottom side US opposite the duct exterior RA. Arranged on the housing bottom side US and also spaced from the actuation axis SA of the actuation connection 2 is a receptacle A for a fixing element FE in order to prevent the actuator 1 from co-rotating with the actuation connection 2 . Thus, as a torque support, the fixing element FE fixes the actuator 1 against twisting.

[0036] VS denotes the device of the invention for securing the actuator 1 mounted on the ...

Abstract

The invention relates to a device for preventing an actuator applied to an outer side of a ventilating pipe from rotating during operation. The actuator comprises a control element for driving an adjusting connection that interacts with a flap arranged in the ventilating pipe, for adusting a gaseous volume flow. The actuator comprises a housing with a lower side located opposite the outer side ofthe pipe. A receiving element for a securing element for protecting against rotation of the actuator is provided on the lower side of the housing, at a distance from an adjusting axis of the adjustingconnector. The device is characterized in that it comprises a flexible strip that has an upper side and an opposing lower side for applying to the outer side of the pipe. The securing element is applied to or embodied on the upper side. The securing element geometrically matches the receiving element in such a way that it can be inserted into the receiving element, together with the flexible strip, with little play, such that the actuator is secured against movement about the adjusting axis. The flexible strip comprises an adhesive layer and / or a magnetic layer consisting of a magnetized ferromagnetic material on the lower side thereof.

Description

technical field [0001] The invention relates to a device for securing an actuator mounted on the outside of a ventilation duct against twisting during operation. The actuator has an actuating member for actuating an actuating connection which cooperates with a flap arranged in a ventilation duct to set the gaseous volume flow, in particular for heating, ventilation or climate of a building control. The actuator has a housing with a bottom side facing the exterior of the ventilation duct. On the bottom side of the housing and spaced from the actuation axis of the actuation connection is a receptacle for a fixing element, which is provided against twisting. Background technique [0002] Devices of this type are known, for example, from WO 2007 / 098620 A1, from CH 707 031 A1 and CH 695 358 A5. [0003] The actuator typically has an electric motor, a reduction gearbox usually connected downstream of the electric motor, and a gearbox side actuation connection for attaching the ...
