Claims

[Scope of utility model registration request]

a cylinder, a roller that rotates inside the cylinder by an eccentric portion of a rotating shaft, and a vane that comes into contact with the roller and divides the inside of the cylinder into a high pressure chamber and a low pressure chamber;
In a rotary compressor that includes a suction passage provided in the cylinder so as to communicate with the low pressure chamber, and a reverse rotation prevention device installed in the suction passage, the reverse rotation prevention valve device is arranged so as to be perpendicular to the suction passage. This anti-reversal valve device is installed in a cylindrical valve chamber provided in a cylinder, and this reverse-reverse prevention valve device includes a valve body in which a plate spring is formed into a cylindrical shape along the valve chamber, a valve piece for opening and closing a suction passage, and a cylinder. 1. A reversal prevention device for a rotary compressor, characterized in that it is formed into one unit with a rotation stopper that is engaged with a rotation stopper.
