Well tubing mandrel with orienting sleeve with trash relieving slot










Image Number 2 for United States Patent #4033409.

A mandrel for use in the well tubing in which the mandrel has an open bore for alignment with the well tubing and a side pocket offset from the open bore for receiving flow control devices and an orienting sleeve in the open bore above the pocket for aligning a flow control device to be positioned in the pocket. The orienting sleeve includes an elongated hollow tubular body with a lower end which tapers upwardly and away from the offset pocket to form a guide surface and a first longitudinally extending slot extends from the highest portion of the tapered guide surface and terminates in spaced relation to the upper end of the sleeve. A second slot of relatively narrow width in relation to the first slot extends from the termination of the first slot to the upper end of the tubular body to form spaced aligned shoulders at the juncture of the first and second slot and a passage way for relieving or discharging trash and debris from the first slot into the well tubing.
