JET PUMP ASSEMBLY INCREASING WINDING-IN FLOW

PROBLEM TO BE SOLVED: To provide structure increasing winding-in of fluid. SOLUTION: A jet pump assembly 200 includes an inlet body 202 disposed near throat structure 214, so that an winding-in port is disposed between a discharge end 208 of an inlet body 202 and the throat structure 214. A drive fl...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide structure increasing winding-in of fluid. SOLUTION: A jet pump assembly 200 includes an inlet body 202 disposed near throat structure 214, so that an winding-in port is disposed between a discharge end 208 of an inlet body 202 and the throat structure 214. A drive flow of propulsive fluid is supplied to the inlet body 202 at a first rate via at least one nozzle 212, and it is discharged at a second rate higher than the first rate, so that pressure drop occurs in the throat structure 214. The pressure drop promotes entrance of a first winding-in flow of suction fluid into the winding-in port and passage of a second winding-in flow of the suction fluid through the inlet body 202 via at least one flow passage 210. At least one flow passage 210 is separated from the drive current while the second winding-in flow passes through the inlet body 202. COPYRIGHT: (C)2011,JPO&INPIT
