ABSTRACT:
The rotary compressor is constructed such that two oil cooler pipes are arranged in the vicinity of two compressing elements located at the opposite ends of an electrically driving element. With this construction, cooling performances of the rotary compressor can be doubled. In addition, since the two oil cooler pipes and two heat exchangers are connected to each other in series, there does not arise a necessity for enlarging a volume of the rotary compressor by increasing a diameter of the same. Alternatively, the rotary compressor may include a cooler pipe for conducting refrigerant to an oil cooler pipe and a fan for simultaneously forcibly cooling an enclosed vessel and the cooler pipe. In this case, since the temperature of refrigerant gas to flow into the oil cooler pipe can be lowered, the lubricant can be cooled at a high efficiency. Thereby, it is provided an enclosed type rotary compressor which can exhibit sufficiently high performances, high properties and high reliability without any necessity for enlarging a volume of the rotary compressor.
