Abstract
A particle exclusion assembly designed to operate in an inclined position and to protect an associated sealing assembly. The assembly includes radially inner and outer relatively rotatable walls and axially inner and outer baffles and a rotary, controlled porosity, open-celled element which substantially fills the cavity between the two walls and the two baffles. The open-celled element controls the rate of movement of particulate material and restricted annular opening is provided to control ingress and egress of particulate material from the open-celled element.
