Abstract
The invention relates to a valve for opening and closing a flow path, comprising a drive motor, comprising a valve disk, comprising a valve tappet and comprising a transmission device for converting rotational movement of the drive motor into translatory movement of the valve disk, wherein the valve disk is connected to the valve tappet and is able to be moved by way of movement of the valve tappet, wherein the transmission device is formed from flexible elements and at least one toothed segment which is mounted so as to be rotatable about an axis of rotation, wherein only tensile forces are able to be transmitted by the flexible elements, and wherein the toothed segment is able to be at least partially wrapped around by the flexible elements by way of rotational movement.
Claims9
A valve for opening and closing a flow path, comprising:
- a drive motor;
- a valve disk;
- a valve tappet, the valve disk is connected to the valve tappet and is moved by way of movement of the valve tappet;
- a transmission device further comprising:
- a plurality of flexible elements and at least one toothed segment which is mounted so as to be rotatable about an axis of rotation, the transmission device able to convert rotational movement of the drive motor into translatory movement of the valve disk;
- a plurality of disk-shaped elements which are part of the at least one toothed segment, a first disk-shaped element of the plurality of disk-shaped elements is arranged on one side of the valve tappet, and a second disk-shaped element of the plurality of disk-shaped elements is arranged on an opposite side of the valve tappet and is rigidly connected to the first disk-shaped element of the plurality of disk-shaped elements, each of the first disk-shaped element of and the second disk-shaped element of the plurality of disk-shaped elements having two grooves which extend in a circumferential direction parallel to one another at an outer circumference of each of the plurality of disk shaped elements, and each of the plurality of flexible elements is guided in a corresponding one of the grooves on a respective one of the plurality of disk-shaped elements;
- wherein only tensile forces are transmitted by the plurality of flexible elements, and each of the plurality of disk-shaped elements is at least partially wrapped around by at least one of the plurality of flexible elements by way of rotational movement.
