Title:
EJECTOR
Document Type and Number:
WIPO Patent Application WO/2014/091701
Kind Code:
A1
Abstract:
This ejector is equipped with: a body section (30) in which a depressurization space for depressurizing a coolant discharged from a revolving space, an aspiration channel for aspirating coolant from the exterior, and a pressurization space for mixing the coolant from the depressurization space and the coolant from the aspiration channel are formed; a conical channel-forming member (35) positioned inside the body section (30); and a drive device (37) for displacing the nozzle body (32) of the body section (30) for forming the depressurization space. An operating rod (38), which forms a nozzle channel (13a) inside the depressurization space on the outer-circumferential side of the channel-forming member (35), forms a diffuser channel (13c) inside the pressurization space on the outer-circumferential side of the channel-forming member (35), and connects the drive device (37) and the nozzle body (32), is positioned so as not to transect the diffuser channel (13c). As a result, it is possible to achieve high nozzle efficiency and high pressurization performance not affected by load fluctuations of the coolant cycle, without necessitating an increase in the size of the structure.
