<P>PROBLEM TO BE SOLVED: To provide a compact jet pump which has the advantage of easy installation in an air conditioning device. <P>SOLUTION: The jet pump ZP includes: a discharge outlet 51a which is configured to discharge a refrigerant formed with a relatively high-pressure refrigerant and a relatively low-pressure refrigerant; a diffuser 55 which is disposed coaxially with the discharge outlet 51a upstream of the discharge outlet 51a having an inner diameter gradually reduced with distance from the discharge outlet 51a; a suction hole 52e configured to guide the low-pressure refrigerant, which continues from the minimum diameter part of the diffuser 55 to the upstream side thereof, and is disposed coaxially with the discharge outlet 51a; a peripheral refrigerant passage 53 configured to guide the high-pressure refrigerant to the diffuser 55; and a nozzle part 59 configured to eject the high-pressure refrigerant from the peripheral refrigerant passage 53 into the diffuser 55 on the downstream side of the minimum diameter part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
