PROBLEM TO BE SOLVED: To constitute an oil supply mechanism for supplying an oil to a gas seal portion of a rotor while improving mountability of a rotary piston engine and improving performance.SOLUTION: A rotary piston engine 1 is disposed so that a long axis Y of a cocoon-shaped rotor accommodation chamber 31 is directed in a vertical direction, and an opening portion 110 of an intake port 11 is disposed on a position at a lower side with respect to an output shaft X on side faces of side housings 4, 5. An oil supply port 73 formed on a rotor housing is formed on a position overlapped to an opening portion of the intake port in a rotating direction of the rotor, a nozzle 71 for supplying the oil is inserted obliquely upward toward a trochoid inner peripheral face from an oblique lower portion of the outer peripheral face to the rotor housing, and a tip of the nozzle is positioned at an inner part with respect to a through bolt 14.SELECTED DRAWING: Figure 5 |
