Abstract
When an ejector having a variable nozzle and a variable throttle mechanism are integrated together as an ejector module, a nozzle-side central axis CLand a decompression-side driving mechanism have a twisted positional relationship, if the nozzle-side central axis CLis defined as a central axis of a nozzle-side driving mechanism in a displacement direction in which the nozzle-side driving mechanism of the ejector having the variable nozzle displaces a needle valve, and the decompression-side central axis CLis defined as a central axis of a decompression-side driving mechanism in a displacement direction in which the decompression-side driving mechanism of the variable throttle mechanism displaces a throttle valve. When viewed from the central axis direction of one of the nozzle-side central axis CLand the decompression-side central axis CL, a driving portion corresponding to the one central axis is disposed to overlap with the other central axis.
