PURPOSE:To suppress and lower the variation of the engine rotation frequency even when the capacity of a variable capacity compressor is converted, by composing the system to convert the current flow to a solenoid in a specific inclination depending on the discharge capacity directed by a conversion directing device. CONSTITUTION:When the discharge capacity of a variable capacity compressor 1 is directed to convert to a different amount by a conversion directing device 2, the conversion direction is discriminated by a discriminating device 3. And when the discharge capacity of the variable capacity compressor 1 is converted depending on the discriminated result, the current flow to a solenoid 1-1 is converted to the discharge capacity directed by the conversion directing device 2 by a control device 4 in a specific inclination. As a result, the discharge capacity is converted slowly in a specific inclination. Consequently, a sudden variation of the variable capacity compressor load to the engine can be avoided, and no large influence is given to the engine rotation frequency. |
