ABSTRACT:
This invention provides a jet pump comprising: a three-dimensional axisymmetric nozzle with a top end and a bottom end, a mixing chamber with a top section and a bottom section, a conical diffuser with a top end and a bottom end, a distributor of a shower cap and an induction passage. The top section of the mixing chamber neighbors the bottom end of the nozzle. At a distal downstream end of the bottom section of the mixing chamber is the top end of the diffuser. The distributor is connected to the bottom end of the diffuser. The nozzle, the mixing chamber, the conical diffuser and the distributor share a longitudinal axis which is perpendicular to longitudinal axis of the induction passage. A pressurized first fluid is injected through an inlet orifice of the top end of the nozzle. Loss of pressure at periphery of the bottom end of the nozzle draws, by suction, a second fluid through the induction passage into the mixing chamber wherein the first fluid and the second fluid are thoroughly mixed to form an entrained mixture. The entrained mixture flows through the mixing chamber into the diffuser wherein sufficient chaotic turbulence is created to minimize wall separation, frictional losses and dissipation of energy to realize substantial recovery of the static pressure that was lost in the nozzle. The diffused mixture is then dispelled from the jet pump through the distributor of the shower cap.
