What is it about?
A technique of calculating the relationships between the discharge pressures in the pumping cavity and the compressor cavity of a hybrid energy-converting piston machine is proposed. Through the use of the results presented here, a relationship is found between the discharge pressure of the pumping cavity and that of the compressor cavity that assures equality between the mass fl ow rates of the liquid traveling out of the pumping and compressor cavities and, correspondingly, normal operation of a hybrid energy-converting piston machine.

Why is it important?
One way of improving the performance of a compressor and a volumetric pump is to combine the two into a single unit, called a “hybrid energy-converting machine”. Piston compressors represent around 80% of the total inventory of compressor machines, while piston pumps are the leading element of the segment of volumetric pumps. Hence, the creation and investigation of volumetric hybrid energy-converting piston machines is an important and critical problem.
Perspectives
The most convenient of all the different constructions of volumetric hybrid energy-converting piston machines in terms of manufacturability of construction and realization of the working processes is one in which the compressor cavity is situated in the upper part of the cylinder (above the piston), and the pumping cavity, in the lower part of the cylinder (beneath the piston)
