Abstract
A rotating control device can include a groove formed on a housing, and an elastomeric ring isolating inner and outer portions of the groove, the elastomeric ring permitting fluid communication between the inner and outer portions of the groove in response to a pressure differential from the inner to the outer portion of the groove. A method can include forming a circumferentially extending groove, providing fluid communication between the groove and an annular area isolated between rotary seals, and positioning an elastomeric ring in the groove, the elastomeric ring preventing fluid flow from an exterior of the groove to the annular area, and permitting fluid flow from the annular area to the exterior of the groove. Another rotating control device can include an elastomeric ring in a groove, and a passage in a housing that provides fluid communication between the groove and an annular area between rotary seals.
