Abstract
Gas cushions are maintained between a piston and a cylinder of a gas lubricated reciprocating engine which are effective in retarding the approach of the piston to the cylinder wall under the thrust of side forces from the connecting rod. The cushion are maintained by viscous flow forces for sufficient time exceed a half cycle of crankcase rotation.
