Hinged rolling piston compressor of a new patented thermodynamic cycle ,Pars engine, promises high performance figures such as single stage high compression levels and higher volume flow discharge with competitively low input power and torque. The pumping characteristic of the present engine compressor unit has been increased by the implementation of a springless vane configuration. The reciprocating vane which is usually operated by spring compression in air conditioning and refrigeration unit has been replaced by a hinge vane mechanism. At high speeds, the conventional spring loaded vane which is forced against the eccentrically moving rotor periphery does disconnect and starts rocking. With the new configuration, this mishap has been eliminated and subsequently resulting compressor pressure leaks have been avoided. The isentropic compression efficiency of the patented hinged vane compressor is around 85% for pressures reaching 9 atm. Pars engine is a new spark-ignition engine but its modular architecture is very similar to that of a gas turbine engine with the presence of separate compression, combustion and expansion unit.

Compression Steps of PARS Compressor


Our purpose is to provide efficient, energy – saver systems and to decrease costs and emissions.

Thanks to original geometry of PARS Compressor, traditional piston compressors give place to more efficient rotary compressors.

Our technologies have been improving more than a decade of development and testing but we have just started to discover potential of it.


The traditional piston and cylinder compressors such as refrigerator or air conditioner are replaced by the technology of PARS Makina.

This technology can be applied anywhere that there is a piston – cylinder mechanism.


We try to change traditional perspective of compressor technology to improve the performance, to increase energy savings and to widen the applicability fields.

We have already successfully licensed PARS Compressor and many others.

We are now seeking new solutions for tiny applications.
