The significant unevenness of the instantaneous power of a piston compressor unit during its operating cycle creates certain problems in the selection and operation of drive engines, which are usually solved by installing a flywheel. In single-stage compressor units with linear drive based on low-speed long-stroke stages, the amplitude change in the gas force during the operating cycle is significantly higher compared to similar compressor units. This leads to such an increase in the amplitude change of the instantaneous power of the drive, that the use of a flywheel becomes impractical. The article discusses the issues of ensuring the required dynamic and energy characteristics of single-stage compressor units with linear hydraulic drive by synthesizing the law of motion of the drive, the piston of which is rigidly connected to the piston of the compressor stage. Design methodology and the results of the computational parametric analysis are presented. The relevance of determining effective laws of motion of the drive as applied to compressor units with linear actuators based on low-speed long-stroke stages is confirmed.

The design of a free piston compressor and an analysis on integrating an external combustion engine into the compressor design are presented in this article. A free piston compressor is a device which converts chemical energy to work on a volume of air through the kinetic energy of an inertia driven piston, which is not rigidly attached to a ground. An external combustion engine serves as in intermediate chamber which transfers combustion gases to a device to perform some work. The following discusses the design and experiments on an external combustion engine, with a focus on eliminating an injection holding force on a free piston compressor’s elastomeric membranes. The efficiency of the external combustion engine to transfer energy without significant losses due to heat, dead volume, air/fuel mixtures, and actuated valve speed are also presented.
