  • Patent number: 6446946
    Abstract: This invention is a shock absorber for a oil well pumping unit. When a oil well is being produced by means of a oil well pumping unit-the pumping unit sits on the ground surface and pumps in an upward and downward motion which works the sucker rod string that runs down the well bore with a oil pump attached to the bottom of the sucker rod string. The sucker rods are attached to the pumping unit by means of a polish rod. The polish rod is the top rod of the sucker rod string. This shock absorber fits over the polish rod and slides down to a desired position. It is attached to the pumping unit by either wire line clamps on the bridle arms or a carrier bar. It will fit any and all oil well pumping units. Other oil well shock absorbers will only fit oil well pumping units with special attachments. This shock absorber is to eliminate pounding and vibration from the pumping unit and sucker rod string.
