Reinforced rotary valve seal assembly

A rotary valve comprising:

• a valve body including an opening formed therein;
• a rotary component received within the opening of the valve body, the rotary component configured to rotate relative to the valve body about an axis of rotation thereof;
• a first sealing structure configured to sealingly engage the rotary component, the first sealing structure including an outwardly extending support feature, wherein the first sealing structure is formed from a substantially rigid material;
• and
• a second sealing structure configured to sealingly engage the first sealing structure and the valve body, the second sealing structure disposed adjacent the outwardly extending support feature of the first sealing structure, wherein the second sealing structure is formed from a resiliently deformable material, wherein the second sealing structure is compressed radially between the outwardly extending support feature of the first sealing structure and the valve body.
