Claims

[Scope of utility model registration request]

(1) Two large and small cylindrical spaces 2 and 3 that intersect with each other are formed inside the casing, and the center line of the smaller cylindrical space 3 is approximately an extension of the inner peripheral surface of the larger cylindrical space 2. A cutoff rotor 5 is disposed above and in the smaller cylindrical space 3, and a cutoff rotor 5 is disposed in the larger cylindrical space 2.
A work rotor 6 having the same diameter as and circumscribing the cutoff rotor 5 is arranged concentrically with the larger cylindrical space 2, and the work rotor 6 has an inner end fixed to the work rotor 6 and an outer end fixed to the work rotor 6. A blocking tooth 9 is disposed facing the inner circumferential surface 4 of the larger cylindrical space 2 with a gap sufficient to maintain a substantially airtight state, and the blocking rotor 5 has the blocking tooth 9 of the size as described above. When passing through the intersection of the cylindrical spaces, a recess 10 is formed through which the cutoff tooth 9 can pass, and the cutoff rotor 5 and the cutoff rotor 6 are rotated at a predetermined angular position in opposite directions at the same rotational speed. In the rotary piston blower, the air inlet 20 is located inside the larger cylindrical space 2. An air intake opening/closing valve 21 is opened at an end face, and rotates together with the work rotor 6 to slide along the inner end face where the air intake port 20 opens to control opening/closing of the air intake port 20. , a rotary piston type blower in which a slit is formed at an end of the cutoff rotor 5 to allow passage of the suction opening/closing control valve.

(2) In the rotary piston type blower, the rotary shaft of either the cutoff rotor 5 or the working rotor 6 is formed as a drive shaft, and a gear device for driving the drive shaft at an increased speed is connected to the rotary piston type blower. The rotary piston type according to claim 1 of the utility model registration claim, which is integrally connected to the housing.
