The paper is a first order analytic description of the performance characteristics of a displacement compressor with floating poppet valves. The valves are actuated by the pressure forces acting on them to allow the compressor to deliver compressed gas at any chosen pressure level. The irreversibilities considered are the losses associated with the flow into and out of the cylinder past the valves of the type described. The performance indices of interest are the adiabatic and volumetric efficiencies as they are affected by the mechanical operating speed of the compressor and the chosen pressure ratio. These performance indices are obtained in terms of non‐dimensional parameters which describe the dimensions of the valves and cylinder as well as the operational characteristics.
