Abstract
Flow diverter apparatus is disclosed having a housing and a piston and annular packer disposed therein. The diverter has passages in the piston and housing walls providing fluid communication between the borehole and a vent line. A valve in the vent line is opened before the packer of the apparatus is closed about a tubular member in the bore of the apparatus or completely closes the vertical flow path of the bore of the apparatus when no object is therein, thereby diverting pressurized borehole fluid away from the rig equipment and personnel.
