Abstract: A cylinder assembly for use as a cylinder comprises an upper outer tubular cylinder and a lower outer tubular cylinder and a stationary sealing ring retained between the upper and lower outer cylinders slideably receiving an inner tubular piston having upper and lower sealing flanges to create upper and lower fluid chambers. Pressurized fluid is selectively directed through flow conduits in the sealing ring into the upper or lower fluid chamber as desired to move the inner tubular piston upward and downward. The upper tubular cylinder supports an attached bearing table and travelling slips. A pipe guide for supporting a length of pipe is positioned in the lower outer tubular cylinder. A mechanism rotating a pipe and pipe string is also provided.

Abstract: A flow line cleanout device for a coiled tubing head of a coiled tubing string is comprised of a hydraulic vane motor assembly having a rotor configured for attachment to and rotation of a work tool such as a fluid ejecting nozzle to be inserted into a flow line. Seals around the device seal the flow line so that fluid pressure behind the coiled tubing head force fluid through the hydraulic vane motor assembly to rotate the rotor and the attached nozzle in response to pressure changes created by check valves. Jets of fluid from the rotating nozzle serve to wash and remove blockages in the flow line and facilitate the insertion and advancement of the coiled tubing string.
