The digital readout concept for rod position was completed, the snubber design was established, and the Aurora pump was tested and found to be satisfactory. Preliminary tests on the flow model revealed binding of the piston and piston rod. It was found to be mechanical in nature and was eliminated by providing a swivel connection between the piston rod and the weight. Tests showed unbalanced pressures in the leakage paths of the control sleeves causing binding of the sleeves. Providing two sets of control ponting, located diametrically opposite to each other, did not reduce the binding in the control sleeves to a satisfactory value. The control sleeves were replaced and tests with the new sleeves showed no improvement in the binding condition. A new piston configuration was established which reduces leakage and provides a strengthened snubbing section. Flow model leakage tests were mm using the new control sleeves. (auth)
