摘要： An ejector including a nozzle communicating with a fluid inlet, a diffuser communicating with a fluid outlet, and a decompression chamber placed between the nozzle and he diffuser. The ejector is arranged to generate a negative pressure in the decompression chamber by a fluid ejected from the nozzle. A target negative pressure P in the decompression chamber is set in a range of “40 kPa
