Abstract

PURPOSE: To stabilize discharge amount and intake amount of fluid as well as to stabilize running of vanes by minimizing pressure difference between rear ends of grooves and a vane chamber in a rotary type fluidic machine including a rotor having the grooves to insertedly slide the vanes.
CONSTITUTION: A rotary type fluidic machine provides a rotor 2 eccentrically allocated in a casing 1. In this case, said rotor 2 provides an air flowing bore 24 which conducts the rear ends 13 of grooves 12 to insertedly slide vanes 14 to a vane chamber 16. Generally, the size of gaps between the grooves 12 and the vanes 14 or gaps between the side surfaces of the rotor 2 and side plates 3, 4 at both ends of the casing 1 makes the size of pneumatic pressure at the rear ends 13 of the grooves change subtlely and complicate air flow between the rear ends 13 of the grooves and the vane chamber 16. However, as stated above, if the air flowing bore 24 is provided, the pressure between the rear ends 13 of the grooves and the vane chamber 16 becomes equal, which makes it possible to stabilize the running of the vanes 14.
