<p>Rotary-type heat engine having the combustion chamber (3) separated from the expansion chamber (4), using the structure of pumping chamber in circumferential piston pump, so that constant-volume combustion process and constant-pressure exhaust process may be continuously performed without valves. Heat is added by combustion of fuel injected into the compressed air of fixed volume confined by rotating small piston like rotor (SPR, 1), heating the fluid to super pressure (SP) and temperature, after which the SP gases flow into expansion chamber (4) and make large piston like rotor (LPR, 2) rotate, expanding to atmosphere. Herein the SP gases are always supplied into expansion chamber (4) just after the gases already entered, fully expanded, are isolated by rotating LPR (2) in order not to mix with the SP gases, so the pressure of exhaust gases transferred to outlet (9) by rotating LPR (2) can come to atmosphere to perform the constant-pressure rejection of heat.</p> |
