A linkage system for use in reciprocating piston machines is described. The linkage mechanism allows for the transmission of reciprocating motion produced by one or more pistons (11a, 11b, 11c, 11d) which is transmitted to a rocker crank (15a) whereby the reciprocating motion is transmitted via throw shaft (18a) to a crank (19). The rocker crank (16a) may have a single or double upper arm connected to one piston in the former construction and two in the latter. Various arrangements of the linkage are envisaged including inverting the rocker crank (16a) as well as reversing the orientation of the rocker crank/throw arm connection. The linkage allows for close piston spacing thereby producing a compact engine. Alternative piston arrangements are possible including inline, V and other orientations. |
