Abstract (en)

[origin: WO2017021176A1] The invention describes a hydro-Stirling engine having at least two hydro-Stirling units (10, 20), having an energy converter unit and having a common working fluid circuit which has, for each hydro-Stirling unit, at least one working fluid line (50, 60) which connects the hydro-Stirling unit to the energy converter unit. To achieve that a driven axle in the energy converter unit can always rotate in the same direction, and in order to realize hydraulic decoupling of the hydro-Stirling units (10, 20), the energy converter unit is a turbine unit (30) which has a turbine vessel (32) and a turbine wheel (34), in particular a Pelton turbine wheel, which is arranged in said turbine vessel (32). Here, the working fluid lines (50, 60) extend between the hydro-Stirling units (10, 20) and the turbine unit (30) such that working fluid that flows from a hydro-Stirling unit (10, 20) to the turbine unit (30) firstly impinges on the turbine wheel (34) and then falls into a region of the turbine vessel (32) below the turbine wheel (34). Furthermore, the working fluid circuit has, for each hydro-Stirling unit (10, 20), at least one working fluid return line (70, 74) which connects the turbine unit (30) to the hydro-Stirling unit (10, 20). Here, each displacement piston unit has a cylinder shell (14, 24) which extends downwardly from the displacement piston (13, 23) and the outer surface of which is substantially aligned with the outer surface of the displacement piston (13, 23).
