Abstract
A rotating control device has a rotating section rotatably supported in a housing. The rotating section has a mandrel and a rotating seal element of a rotary seal sealingly affixed to an exterior of the mandrel. The housing has sealingly disposed therein a non-rotating seal element of the rotary seal. The non-rotating seal element is in at least partial axial and radial alignment with the rotating seal element and is movable longitudinally with respect to the housing. The non-rotating seal element has a protrusion extending from a face disposed toward the rotating seal element. Fluid pressure acting on the non-rotating seal element acts on a larger surface area on a face opposed to the rotating seal element than on the face disposed toward the rotating seal element.
