Claims

[Scope of utility model registration request]

A vehicle air conditioner comprising a rotary compressor, the rotary compressor having a working chamber defined within the compressor for sucking and pressurizing fluid, and a discharge space for the fluid pumped from the working chamber being formed within an envelope enclosing the compressor. In the apparatus, an actuator for reducing a passage area is provided in the middle of a suction passage for sucking fluid into the compressor,
A high-pressure passage branched from the discharge passage of the compressor is provided in communication with the diaphragm chamber of the actuator, and the high-pressure passage is opened in the middle of the high-pressure passage according to predetermined vehicle operating conditions, and the actuator is operated to allow passage of the suction passage. A vehicle cooling device characterized by being provided with a solenoid valve that reduces area.
