Abstract
The invention relates to a rotating regulating device, especially for a valve comprising a pivotable or rotatable valve body. Said device comprises at least one actuating device for rotating a regulating element which can be connected to the valve body in a moveable manner. The aim of the invention is to improve one such rotating regulating device in such a way that in its precise and reproducible, and can be especially automatically actuated. In order to achieve this, the regulating element is a rotating collar which is rotationally positioned in relation to a bearing collar, and the actuating device comprises at least one mechanism which converts a linear movement into a rotational movement.
Claims27
A rotary adjusting device comprising:
- an operating element coupled to an electro motor and operable to linearly translate in response to rotation of said electro motor;
- an adjusting element coupled to said operating element, wherein said adjusting element comprises a rotary sleeve mounted so that it can rotate relative to a bearing sleeve;
- at least one transmission adapted to translate a linear motion into a rotary motion, wherein the rotary sleeve and the bearing sleeve each have at least one guide slot in their circumferential surfaces, one of which runs essentially in a straight line and the other essentially diagonally to the longitudinal direction of the sleeves;
- and
- a meshing element, such as a meshing pin, which engages both slots and runs perpendicular to the longitudinal direction of the rotary adjusting device.
A rotary adjusting device comprising:
- an electro motor;
- an operating element coupled to said electro motor and operable to linearly translate in response to rotation of said electro motor;
- an adjusting element coupled to said operating element and operable to rotate in response to linear translation of said operating element;
- a transmission coupled to said operating element and said adjusting element, wherein said transmission is operable to convert linear translation of said operating element into rotation of said adjusting element, wherein said transmission further comprises:
- a pin coupled to said operating element and arranged perpendicular to the longitudinal axis of said operating element;
- and
- a first slot disposed in a rotary sleeve of said adjusting element, wherein said slot runs diagonally to the longitudinal axis of said adjusting element, wherein said pin is engaged with said first slot.
