NEW GAS COMPRESSION TECHNIQUES.
Abstract
A free-piston, gas-lubricated compressor concept was analyzed and a feasibility demonstration model was fabricated and tested. The main body contained two solenoids, the motor stator, a valve assembly, and a compression chamber at each end. The rotor assembly included two solenoid cones, a permanent magnet core for the motor rotor, nonmagnetic spacers, and a piston at each end. The rotor assembly was made to rotate and translate through the action of the motor and solenoids. Rotation of the rotor generated a hydrodynamic gas-bearing and translation gave the reciprocating action necessary to compress the gas in the cylinders at each end. The original concept also called for special porting in the cylinder and pistons which would be opened and closed at specific times through the synchronized rotary and translational motion of the piston. This concept was not attempted experimentally but instead conventional poppet valves were used. Difficulties were encountered with the gas-bearing caused by dust and high spots on the rotor as the rotor assembly was not dimensionally stable. Motor starting torque was also marginal. It was concluded that the disadvantages of the compressor do not justify its further development. (Author)
