Abstract
We had designed and prototyped original gamma-type circulating flow stirling engine (CFSE) with pulse converter branch and confluent connection in operating gas flow for application of waist has recovering, low temperature differential Stirling engine. Though the pulse converters are incomplete preventing reverse flow compared with lead valve, they are simpler, low pressure loss and wide section area, it could change the heater and cooler flow into counter flow heat exchanger. A One-cylinder, 1.0kw experimental CFSE model is manufactured. In addition, DP and PP are connected by oval-gear drive for enhancement of indicated power. For cancel the side thrust of DP and PP, contra-rotating drive system is adopted.
