INJECTOR FOR CRYOGENIC LIQUID Russian patent published in 2014 - IPC F17C9/00 

FIELD: machine building.

SUBSTANCE: cryogenic liquid injector includes a cryogenic liquid inlet assembly, a cryoreservoir and a cryogenic liquid outlet assembly. The inlet assembly includes a nozzle with an external thread, which has a channel along the axis, which is connected through a capillary to a compressed gas bottle, a transition branch pipe with a thread on inner surface for screwing of the nozzle and with through axisymmetrical holes; with that, the nozzle can have two positions: a) holes are covered and cryogenic liquid does not enter the cryoreservoir; b) holes are open and cryogenic liquid enters the cryoreservoir, and a pipeline attaching the inlet assembly to the cryoreservoir. The outlet assembly includes a discharge pipeline with a coupling and a flange with a membrane in the form of a disc, which is pressed to the outlet hole of the cryoreservoir by means of a washer plate, the inner diameter of which is chosen depending on the value of pressure required for membrane rupture, and a hold-down nut. Helium or liquid nitrogen is used as compressed gas. Liquid methane is used as cryogenic liquid.

EFFECT: intensifying a hydrate formation process.
