In a Stirling engine having a housing chamber (1) which is divided by a reciprocating gas-permeable regenerator plate (4) into two part chambers (6, 7), of which one can be heated and the second is provided with cooling (13), the second part chamber (7) communicating with a working cylinder which acts on a working shaft (14) or a flywheel mass (10) via a first drive device (9) and on the regenerator plate (4) via a second drive device, it is proposed to design the housing chamber (1) in a wedge-shape and to mount the regenerator plate (4) pivotably about a pivoting axis (5) in the tip of the housing chamber. As a result of the proposed design of the housing chamber (1) with the pivotable fixing of the regenerator plate (4) which at the same time serves as a displacement piston, the displacement function of the regenerator plate (4) is fully effected by low-wear pivoting motion about the pivoting axis (5).
A stirling engine having a housing chamber divided by a reciprocating gas-permeable regenerator plate into two part chambers, of which one can be heated and the second has cooling, the second part chamber communicating with a working cylinder which acts on a working shaft via a first drive device and on the regenerator plate via a second drive device, wherein the housing chamber (1) is of wedge-shaped design and the regenerator plate (4) is mounted pivotably about a pivoting axis (5) in the tip of the housing chamber, characterized in that the regenerator plate (4) and the two boundary walls (2, 3) of the housing chamber (1), which are located opposite the former, are designed in the shape of cylinder segments, the curvatures of the boundary walls (2, 3) and of the regenerator plate (4) being mutually matched.
A stirling engine having a housing chamber divided by a reciprocating gas-permeable regenerator plate into two part chambers, of which one can be heated and the second has cooling, the second part chamber communicating with a working cylinder which acts on a working shaft via a first drive device and on the regenerator plate via a second drive device, wherein the housing chamber (1) is of wedge-shaped design and the regenerator plate (4) is mounted pivotably about a pivoting axis (5) in the tip of the housing chamber, characterized in that the boundary wall (2) of the heatable part chamber (6) consists of a transparent material and the regenerator surface opposite thereto is provided with a gas-permeable light absorber (12).
