Document Type and Number:
WIPO Patent Application WO/2019/147075
Kind Code:
A1
Abstract:
The present invention relates to an injection nozzle assembly comprising: a nozzle body comprising a first receiving space, an inlet port through which an injection solution supplied from an external supply source flows into the first receiving space, and a first outlet port through which the injection solution is discharged from the first receiving space; a needle having a head equipped so as to open and close the first outlet port; and an elastic member which, in the case where the hydraulic pressure of the injection solution flowing into the first receiving space is the same as or greater than a predetermined reference hydraulic pressure, elastically biases the needle, so that the head is spaced apart from the first outlet port, and the first outlet port is open.
