Abstract
A rotary valve, comprising a valve housing with a valve chamber, wherein the valve chamber has a chamber wall in which at least two fluid openings are provided, wherein the valve chamber has a receiving opening on the end face side, wherein the valve chamber accommodates a valve core, wherein the valve core is provided with a channel structure which interacts with the fluid openings, wherein the valve core is supported in the valve chamber in a rotationally movable manner, wherein the valve chamber is formed in a conical shape.
Claims15
A rotary valve comprising:
- a valve housing with a valve chamber, wherein the valve chamber has a chamber wall in which at least two fluid openings are provided, wherein the valve chamber has a receiving opening on an end face side, wherein the valve chamber is delimited by the chamber wall and a chamber bottom, wherein the chamber wall surrounds the valve core, wherein the chamber bottom includes chamber ramp elements,
- a valve core accommodated in the valve chamber, wherein the valve core is provided with a channel structure which interacts with the fluid openings, wherein the valve core is supported in the valve chamber in a translationally and rotationally movable manner, wherein the valve core includes core ramp elements in abutment with the chamber ramp elements, and
- a selector shaft non-rotatably connected to the valve core for rotation therewith, the valve core translationally moveable relative to the selector shaft,
- wherein the valve chamber is formed in a conical shape.
