Claims

[Scope of utility model registration request]

A substantially triangular rotor that rotates planetarily around an eccentric shaft is fitted into an engine casing in which both sides of a rotor housing having a trochoidal inner circumferential surface are covered with side housings. an intake port is opened at a position facing the working chamber of the engine casing, and the intake port is rotated by rotationally driven in a valve insertion hole formed inside the engine casing. In an intake device for a rotary piston engine which is opened and closed by a valve, the intake port and the valve insertion hole are connected to each other at a suitable place in the communication passage, on the inner surface of the communication passage or on the communication passage. An intake device for a rotary piston engine, characterized in that a foreign matter discharge section is formed that acts to discharge foreign matter adhering to the outer circumferential surface of the facing rotary valve to the working chamber side.
