Patent ID: 7861944

Claim:
A non-zero-net-mass-flux jet device for providing a non-zero-net-mass-flux jet and transporting a first fluid to an external space, comprising: a chamber, having a nozzle and a lateral channel, wherein the lateral channel is disposed along the outer side of a first side of the chamber, the nozzle is disposed at one end of the lateral channel and the chamber is connected with the lateral channel via the nozzle, the nozzle being connected with an external space, wherein the first fluid is supplied from a source independent of a second fluid in the external space to the lateral channel flows between the source and the chamber through the lateral channel and is filled in the chamber, the nozzle and the lateral channel and an arc and a block are disposed at the connection of the nozzle and the lateral channel; and a piston disposed at a second side of the chamber, activated with a reciprocating motion generated by an activating device and jetting, via the reciprocating motion, the first fluid out of the chamber through the nozzle.
