Abstract (en)

[origin: WO2020254501A1] The invention relates to a radial reciprocating engine (1) having cylinders (5) arranged in a cylinder carrier (16) and a piston element (21) arranged in every cylinder (6), which piston element is connected to a guide element (22), wherein the guide element (22) runs on a sliding surface (14), as a result of which a stroke movement is imposed on the piston element (21). Because the piston element (21) is spherical, at least in the region of the piston element (21) which effects a seal during the stroke movements on inner walls (51) of the cylinder (5), a linear seal is created which allows a more compact design compared to radial pumps having cylindrical piston elements.
