Abstract
Official abstract text for this publication.
A valve arrangement including a sealing element is provided. The valve arrangement includes a housing having a port. A rotary valve body includes an opening, and the rotary valve body is arranged within the housing. The port of the housing and the opening of the rotary valve body are alignable with each other via rotation of the rotary valve body in the housing. A sealing element is arranged within the port. The sealing element includes a seal body having a first axial end engaged against the rotary valve body and a second axial end including a resilient axially compressible portion that engages against a seat in the housing. The resilient axially compressible portion of the sealing element preloads the sealing element axially against the rotary valve body.
First claim
Opening claim text (preview).
What is claimed is: 1. A valve arrangement comprising: a housing including a port; a rotary valve body including an opening, the rotary valve body arranged within the housing, and the port of the housing and the opening of the rotary valve body are alignable with each other via rotation of the rotary valve body in the housing; and a sealing element arranged within the port, the sealing element including a seal body having a first axial end engaged against the rotary valve body and a second axial end including a resilient axially compressible portion that engages against a seat in the housing, and the resilient axially compressible portion of the sealing element preloads the sealing element axially against the rotary valve body and includes an at least partially radially extending protrusion that extends radially inwardly in the port and is arranged radially inward relative to the first axial end of the seal body and defines a first sealing lip. 2. The valve arrangement of claim 1 , wherein the seat is defined in or around the port. 3. The valve arrangement of claim 1 , wherein the seat is defined by a fitting in the port. 4. The valve arrangement of claim 1 , wherein the sealing element is formed from an elastomeric material. 5. The valve arrangement of claim 1 , wherein the second axial end of the sealing element includes a second sealing lip. 6. The valve arrangement of claim 5 , wherein the second sealing lip is arranged radially outwardly from the resilient axially compressible portion. 7. The valve arrangement of claim 5 , wherein the second sealing lip engages against a radially inner surface of the port of the housing.
