Title:
EJECTOR
Document Type and Number:
WIPO Patent Application WO/2014/010162
Kind Code:
A1
Abstract:
This ejector is configured by causing a refrigerant pathway, which is formed between the inner peripheral surface of a decompression space (30b) formed within a body section (30) and the outer peripheral surface of a valve body (35) that alters the refrigerant pathway area of a lowest area section (30m), to function as a nozzle, and causing a refrigerant pathway, which is formed between the inner peripheral surface of a pressure boosting space (30e) formed within the body section (30) and the outer peripheral surface of a pathway forming member (36), to function as a diffuser. Furthermore, the valve body (35) and the pathway forming member (36) are formed as separate members, and by means of reducing the load that the valve body (35) incurs from the refrigerant, a drive device (37) that displaces the valve body (35) can be made more compact. As a result, it is possible to increase the compactness of the ejector, which can exert high energy-conversion efficiency regardless of thermal loading in an ejector refrigeration cycle.
