as to form a dynamic sealing. The dynamic sealing separates the space between the rotor and the
cylinder surface to be two parts, one is air inlet antrum, and the other one is compressing antrum.
During very rotation of the eccentric shaft, the air will enter inside the inletting antrum and meanwhile
the compressing antrum will complete the compressing and the ejecting process accordingly. The main
impress of the rotary compressor is a liquid-gas separator (Liquid receiver) attached to the side of the
compressor. Please refer to picture 2-2;

direct entry of the liquid refrigerant to the compressor, the
he common gas & liquid separator (Refer to Picture 2-3) consists of the cylinder, air-inlet pipe and
In case of the liquid impact caused by the
liquid-gas separator is mounted between the evaporator and the compressor of the air-conditioner. The
function of the separator is not only a separation of the gas and liquid refrigerant, but also a storage for
additional liquid refrigerant produced in the refrigerating cycle. It can automatically adjust the
supplying quantity of refrigerant liquid according to the load variety for avoiding the compressor’s
liquid compression
.
With this function, the gas & liquid separator is also called Liquid receiver.

“U” air-vent pipe etc. There is an oil-sucking hole at the bottom of the “U” pipe. When the compressor
working, the gas and liquid refrigerant come from the evaporator will flow into the gas & liquid
separator. The liquid refrigerant falls into the bottom of the cylinder because of gravitation, only the
gas refrigerant will be sucked into the compressor. The liquid refrigerant at the bottom of sleeve can
only be allowed after being boiled gasified by absorbing heat. The refrigeration oil at the bottom of
the cylinder, after being separated from the liquid refrigerant and being located at the above of the
liquid, will be absorbed by the compressor by passing through the oil-sucking hole together with the
gas. When the compressor stops working, the pressure-balancing hole can prevent the redundant
refrigerant of the separator’s flowing into the compressor through the oil-sucking hole. This type gas
& liquid separator are popularly applied in the heat pump model air-conditioner with To-and-fro type
compressor. It can prevent the liquid refrigerant being brought into the compressor at the moment of
exchange between heating and refrigeration process.
The structure of the Rotary type separator is as the picture 2-4. It’s mainly composed by the straight
air-inlet pipe, “J” air-vent pipe and the pole sleeve. There is no connection between two pipes. The
separator is connected with the compressor by the air-inlet pipe. The filter net at the entrance of the
separator has the function of gas & liquid separating, noisy eliminating and filtering. Passing through
the air-inlet pipe, the refrigerant from the evaporator flows into the separator. Therein, the liquid
refrigerant that passing through the filter net falls to the bottom of the sleeve, and will climb to the
upper of the air-vent pipe until being absorbed by the compressor after being gasified in case of liquid
