5. 2 one-way valve
When the compressor is stopped, since the refrigerant gas will return from the condenser to
the compressor, the rotor will rotate in the opposite direction to balance the pressure; for this
reason, the general standard configuration of the compressor is equipped with a one-way
valve valve (Figure 5-A, Figure 5-C) to prevent rapid backflow of excess high pressure gas.
Note: When the compressor stops, a sound will be heard. This sound is unique to
the rotor reversal. The sound duration should not exceed 3S. Otherwise, check whether
the check valve needs to be replaced.
5. 3 Rubber shock pad
The installation method of the rubber shock absorber is shown in Figure 5-D.
The deformation of the rubber shock pad after the self-locking bolt is tightened is about
0.5mm lower than that in the relaxed state.
