<P>PROBLEM TO BE SOLVED: To enhance the pressure fluid energy converting efficiency through reduction of the counterflow resistance as improvement of the conventional construction in which the bore of an energy converting tube is made greater than that of an air layer forming pipe in consideration of dispersion of the jet stream jetted out of the air layer forming pipe, which results in generation of a gap within the energy converting tube, and generation of a counterflow resistance in the energy converting tube owing to a negative pressure generated in the first energy takeout space. <P>SOLUTION: Before reaching the energy converting tube 61, the pressure flow jetted out of the air layer forming pipe 58 passes through a suction chamber space 68 where the distance is approximately the same as the inner diameter of a suction pipe 63, wherein the periphery of the pressure flow is covered with a pressure flow containing air, and because it is squeezed and compressed by a straightening groove in the air layer forming pipe to become a high-speed straight flow, so that the straightness in advancing is increased and the flow, without dispersing, rushes into the energy converting tube having the same diameter as the hole diameter of the air layer forming pipe. The pressure flow inlet end face of the energy converting tube is formed in a wide angle, which decreases extremely the pressure flow which considerably decreases rushing into the energy converting tube. <P>COPYRIGHT: (C)2013,JPO&INPIT |
