摘要

A prototype of a crossheadless hybrid piston power machine is developed based on a basic diagram protected by a patent for an invention. An experimental investigation of the crossheadless machine as well as of a crosshead hybrid piston power machines with a smooth, respectively, multistep groove seal is carried out. It is experimentally demonstrated that the surface temperature of the valve plate and the temperature of the intake gas developed by the new crossheadless hybrid piston power machine is, correspondingly, 10-15 K and 6-8 K lower than the comparable temperatures of a crosshead hybrid piston power machine with smooth, respectively, multistep slot seal. Improved cooling of the compressible gas makes it possible to increase the volume efficiency of the compressor section and its indicated efficiency.
