Abstract (en)
[origin: WO0026505A1] In a split-cycle machine having a primary axis and comprising: a plurality of radially reciprocal pistons (60) disposed radially of said primary axis; and a circular array of lobed shafts (62) constrained for orbital motion about said primary axis, each shaft being rotatable about a respective secondary axis parallel to the primary axis, the shafts being rotatably driven by drive means at a rate being a predetermined proportion of their orbital rate, and the planes of the lobes lying approximately in the radial plane of the pistons, and wherein during the rotation and orbit of the shafts and reciprocation of the pistons each piston is connected with at least one lobe for rotation and orbit of the shaft in unison with reciprocation of that piston; wherein a non-equiangular positioning of the axes of consecutive Geneva wheel sets (20, 30, 40) provide an increase and/or decrease in the time period of at least one stroke of a cycle of an operation of the machine. A couple of the non-equiangular arrangement with asymmetric lobes on the Geneva Wheels enables a wide range of cycle performance characteristics to be effected.
