Abstract
A plunger assembly arranged to minimize uneven wear spots thereon during the plunger assembly's horizontal and vertical travel within a hydrocarbon producing well conduit. The plunger assembly comprises an elongated central mandrel having a bore extending longitudinally therethrough for transmitting gaseous fluids from a well, through the plunger assembly, a pair of longitudinally spaced-apart sets of arcuately shaped wear pads guidably supported on outer portions of the elongated central mandrel, and at least one tangentially directed nozzle arranged to direct gaseous fluids from the bore of the elongated central mandrel against an inner side of at least one of the arcuately shaped wear pads arranged on the outer portions of the elongated central mandrel.
