    • An energy converter (201) operating according to the Stirling, Ericsson, or similar thermodynamic cycle and being power-controlled by adjustment of the mean pressure of the working gas with the aid of at least one pressure tank (214) which is filled with working gas and connected to the cylinder(s) of the energy converter and in which the gas pressure is substantially higher than the mean pressure, thus enabling an increase of the latter; at least one gas pump (213) which at the exhaust side communicates with the pressure tank and at the inlet side generates a negative pressure enabling a decrease of the working-gas pressure; and valves (215, 216) for controlling both the pressure increase and decrease. Further, the energy converter accommodates at least one low-pressure tank, e.g. the crankcase (211), which is filled with working gas and in which the gas pressure is substantially below the mean pressure. The low-pressure tank communicates both with the inlet side of the gas pump and, via the valve for controlling the decrease in mean pressure, with the cylinder of the energy converter, the total volume of the low-pressure tank being much larger than the stroke volume of the energy converter.
    • 根据斯特林,爱立信或类似热力学循环操作的能量转换器(201),并且通过借助于至少一个充满工作的压力罐(214)调节工作气体的平均压力来进行功率控制。 气体并且连接到能量转换器的气缸,并且其中气体压力显着高于平均压力,从而能够增加后者; 在废气侧与压力罐连通并且在入口侧的至少一个气泵(213)产生能够降低工作气体压力的负压; 以及用于控制压力增加和减小的阀门(215,216)。 此外,能量转换器容纳至少一个低压罐,例如, 曲轴箱(211),其充满工作气体,其中气体压力基本上低于平均压力。 低压罐与气泵的入口侧连通,并且通过用于控制平均压力降低的阀与能量转换器的气缸连通,低压罐的总体积远大于 能量转换器的行程体积。
