Abstract

PURPOSE: To prevent a working fluid from being polluted by a lubricating oil when the operation of a Roots blower is stopped by balancing pressures in both the side chambers in the axial direction of a rotor shaft at a certain ratio via a diaphragm type accumulator.
CONSTITUTION: When the operation of a Roots blower is stopped, the first chamber 33 of a diaphragm type accumulator is contracted while, on the other hand, the capacity of a second chamber 34 is increased in connection with the contraction of the first chamber 33, to reduce pressure in a timing gear box 3 and keep the balance of pressures in both the side chambers in the axial direction of a rotor shaft. Thereby, a lubricating oil will not leak out into a working chamber due to pressure remaining in the timing gear box 3.
