Claim 1:
2. A hydraulic set packer system, comprising:
an outer sleeve;
a mandrel extending through the outer sleeve;
a setting port extending through a radial wall of the mandrel, the setting port configured to provide fluid communication from a central bore of the mandrel to a setting chamber formed between the outer sleeve and the mandrel;
a piston configured to move axially along the mandrel in response to a setting pressure in the setting chamber, the piston configured to drive at least one radially actuatable component to actuate in a radial direction to engage a wellbore wall; and
a pressure isolation assembly disposed in the setting chamber, the pressure isolation assembly configured to move axially with respect to the mandrel from a first position to a second position to seal the setting port, wherein the pressure isolation assembly comprises a pressure isolation ring having a radial through-bore such that fluid may flow into the setting chamber from the central bore in the first position.
