CONVERTER OF THERMODYNAMIC PROCESSES INTO MECHANICAL WORK Russian patent published in 2014 - IPC F02B41/06 F01B29/02 

FIELD: engines and pumps.

SUBSTANCE: expansion cylinder is connected with hot gas source via inlet pipe with valve and mid cylinder via bypass channel with valve. Mid cylinder is connected with coolant chamber via connection channel with discharge valve while coolant chamber is communicated with atmosphere via discharge pipe with used gas discharge valve. Inlet pipe valve is opened at expansion stroke when expansion cylinder displaces from TDC to BDC at closed bypass valve. Bypass channel is open at expansion strike end at inlet pipe valve closed to bypass expanded gas from expansion cylinder to coolant chamber via bypass and connection channels with opened discharge valve at mid cylinder piston nearby its TDC to proceed with gas expansion in coolant chamber with subsequent ejection of used gases in atmosphere via discharge valve and discharge pipe. At expansion cylinder piston displacement from TDC, residues of expanded gases are bypassed from expansion cylinder into mid cylinder at closed discharge valve and closed release valve. Coolant chamber is equipped with heat exchanger to bleed heat from residual expanded gas to its rarefaction and at mid cylinder piston displacement from its BDC said discharge valve is open to communicate mid cylinder with coolant chamber and to displace mid cylinder piston to TDC at rarefaction effects created in coolant chamber. Proposed device allows conversion of maximum possible amount of heat to useful work by exploiting of reverse thermodynamic process.

EFFECT: higher engine efficiency.
