Abstract
A valve includes a housing and a rotary body arranged notably therein with a through opening for a fluid, wherein a flow path is shut off or is at least partially opened in accordance with the rotational angle position of the rotary body about an axis of rotation, wherein the rotary body is connected to a spindle by which the rotary body is rotatable, wherein the housing is provided with a covering, and wherein the spindle reaches through the covering. The spindle is dynamically sealed by a sealing device which follows movements of the spindle relative to the housing and/or to the covering.
Claims10
A valve, comprising a housing and a rotary body arranged rotatably therein, with a passage opening for a fluid,
- wherein a flow path is shut off or at least partially opened according to the rotational angular position of the rotary body about a rotation axis;
- wherein the rotary body is connected to a spindle by means of which the rotary body can be rotated;
- wherein the housing is provided with a cover;
- and
- wherein the spindle extends through the cover;
- wherein the spindle is dynamically sealed by a sealing device which follows movements of the spindle relative to the housing and to the cover;
- wherein the sealing device has a first compression ring and a second compression ring;
- wherein several sealing components are received axially between the compression rings;
- and
- wherein the sealing device houses the sealing components inside the sealing device under spring tension of a spring device inside the sealing device;
- and wherein the first and second compression rings are connected to ensure that the sealing components arranged between the first and second compression rings remain pressed together.
