专利汇可以提供Hot exhaust gas recirculating system for a stirling engine专利检索,专利查询,专利分析的服务。并且An apparatus for a Stirling type engine is disclosed which is effective to aspirate spent exhaust gases into a downstream jet eminating from the outlet of a blower for the induction system of the engine.,下面是Hot exhaust gas recirculating system for a stirling engine专利的具体信息内容。

1. In a Stirling type engine, having an external heating system for operating a closed high pressurized working gas system, the combination comprising: a. a heat source circuit having an induction portion, a combustion portion and an exhaust portion, b. variable speed blower means in said circuit having an outlet, said blower means being effective to draw ambient air along a streamline into said induction portion, c. a recirculation passage connecting said exhaust portion and induction portion, and d. connection means having an aspirator, said means providing a joint between said recirculating passage, induction portion, and blower outlet, said aspirator being located at the immediate outlet of said blower to maximize flow velocity and provide a variable pressure differential between the pressurized low temperature blown air and the high temperature low pressure exhaust gases, said differential being varied in direct response to the outlet velocity of said blower means.
2. The combination as in claim 1, in which said aspirator means comprises a nozzle disposed about the outlet of said blower to create a jet of blown air and a low pressure zone surrounding said jet of blown air.
3. The combination as in claim 1, which further comprises a preheating wheel effective to exchange a substantial portion of the heat content of said spent gases to the streamline of inducted air at a location downstream from said connection means, said inducted air thus being heated by two paths, one including the preheater wheel and the other including the latent heat of said exhaust gases which are recirculated to said inducted air.
