Abstract
A cylindrically curved rectangular face seal is provided for a cross-ported barrel type rotary valve member. The seal has a central flow orifice therethrough with an annular raised rib formed about the orifice and extending in a radial direction from the concave inner face of the seal. The opposite edges of the seal extending in an axial direction each have a notch or rib thereon for axial sliding engagement in grooves provided in the valve body. The annular rib about the orifice accommodates dimensional variation in the valve parts to ensure a rotary sliding seal on the rotary valve member.
