阅读：490发布：2021-07-18

专利汇可以提供Idling speed control for stirling cycle engine专利检索，专利查询，专利分析的服务。并且An idling speed control is provided for a Stirling cycle engine wherein a variable volume working space is provided by a selectively controlled series of dead volume chambers. The idling speed control comprises a dual action system loading the engine in response to (1) a governor speed setting by coupling an electrical generator loaded by a heater resistor in the air flow path to the burner to increase shaft load and (2) a temperature responsive feedback system to decrease the supply of fuel and air to the burner when said heater raises the temperature.，下面是Idling speed control for stirling cycle engine专利的具体信息内容。

权利要求

1. A Stirling cycle hot gas engine power control system comprising in combination, a power shaft driven by said engine, an electric generator connected to said power shaft to load the engine, an air delivery duct to supply combustion air to said engine, a heater resistor located in said duct and coupled to said generator, and speed responsive switching means connecting said resistor to said generator when the engine speed exceeds a predetermined speed.

2. A system as defined in claim 1 wherein the engine is provided with a working space and a control system including a plurality of dead volume chambers, a valve coupling each said chamber with said working space of said engine, and means selectively operating said valves to control the effective size of said working space.

3. A system as defined in claim 2 wherein each valve is spring biased in an open position, and said means operating the valves close them to act as a non-return valve allowing flow of gas only in the direction out of the respective dead volume chambers.

4. A system as defined in claim 2 including a further dead volume chamber and control valve coupled between said plurality of chambers and said working space, and means selectively operating the control valve of said further chambers.

5. A system as defined in claim 1 including temperature sensing means responsive to changes of air temperature in said duct, and control means reducing the flow of fuel to said engine when the air temperature is increased.
