Adjusting element device

Abstract

A device to be used with an adjusting element comprising a rod piston ( 3 ) displaceable with the aid of a motor ( 4 ) in a piston tube ( 2 ). The motor ( 4 ) is rotatably arranged at the adjusting element ( 1 ) through a worm gear ( 6 ), either directly or through a motor attachment ( 5 ), wherein the motor ( 4 ) extends in an extension plane in parallel with the piston tube ( 2 ), said worm gear ( 6 ) having a throat formation ( 7 ) for axial fixation of the position of the motor ( 4 ) in the adjusting element ( 1 ) while a free rotation of the motor ( 4 ) is practicable through 360° in order to make possible, in applications with limited space, an eligible position fixation of the motor ( 4 ) in a predetermined angle in relation to the adjusting element ( 1 ).

1. A device to be used with an adjusting element comprising a rod piston ( 3 ) displaceable in a piston tube ( 2 ) with the aid of a motor ( 4 ), characterized in that the motor ( 4 ) is rotatably arranged at the adjusting element ( 1 ) through a worm gear housing ( 6 ), either directly or through a motor attachment ( 5 ), wherein the motor ( 4 ) extends in an extension plane in parallel with the piston tube ( 2 ), said worm gear housing ( 6 ) having a throat formation ( 7 ) for axial fixation of the position of the motor ( 4 ) in the adjusting element ( 1 ) while a free rotation of the motor ( 4 ) is practicable through 360° in the extension plan in order to make possible, in applications with limited space, an eligible position fixation of the motor ( 4 ) at a predetermined angle in relation to the adjusting element ( 1 ). 
     
     
       2. A device according to  claim 1 , characterized in that the throat formation ( 7 ) of the worm gear housing ( 6 ) can be fixed perpendicular in relation to the adjusting element ( 1 ) in a gear housing ( 10 ) at the attachment portion ( 9 ) of the adjusting element. 
     
     
       3. A device according to  claim 1 , characterized in that the throat formation ( 7 ) of the worm gear housing ( 6 ) has a circumferentially surrounding groove ( 8 ) for cooperation with at least one locking pin ( 14 ) at the fixation of the adjusting element ( 1 ) at the throat formation ( 7 ) and which locking pin ( 14 ) at the same time extends through bores ( 15 ) in the gear housing ( 10 ) of the adjusting element ( 1 ). 
     
     
       4. A device according to  claim 1 , characterized in that the attachment portion ( 9 ) of the adjusting element ( 1 ) has a rotatable, rear attachment ( 11 ) the position of which can be locked. 
     
     
       5. A device according to  claim 4 , characterized in that the rear attachment ( 11 ) of the adjusting element ( 1 ) has a fixation throat ( 12 ) provided with a groove, which can rotate in a recess ( 17 ) in a gear housing ( 10 ) and the position of which can be locked, while at the same time the attachment ( 11 ) can be axially locked in this recess by at least one locking pin ( 13 ) cooperating with the groove ( 16 ) of the throat ( 12 ) and bores ( 18 ) in the gear housing ( 10 ) in association with the recess ( 17 ).
