Abstract: A servo device for regulating a refrigerant into a compressor comprises a low pressure regulator, a high pressure regulator, and a solenoid valve. The low pressure regulator is connected to an inlet of the compressor and the high pressure regulator is connected to an outlet of the compressor. The solenoid valve is communicating with the low pressure regulator and the high pressure regulator respectively. The low pressure regulator further comprises a cylindrical plunger and a spring. The plunger is located in the low pressure regulator and the spring is located at lower end of the plunger to bias against the plunger. The plunger is pushed to move upward intermittently by a refrigerant coming from the high pressure regulator via the solenoid valve so that the refrigerant entering the compressor is hindered by the plunger to correspond with a state of optimal cooling in an air conditioning system or in a mechanical refrigeration system.
