Patent ·
OSTI ID:6051372
An improved free piston Stirling cycle engine of the type having a displacer and a piston reciprocating in a cylinder formed in a housing and having a working gas flow path from a hot space adjacent one end of the displacer to a cold space adjacent the opposite end of the displacer is described wherein the improvement comprises: linkage means for being actuated in response to the excursion of the piston beyond a selected first amplitude; and valve means in the gas flow path connected for actuation by the linkage means for restricting the flow path for the working gas between the hot space and the cold space in response to piston excursion beyond the selected amplitude.
