Abstract
A free piston, Stirling engine is provided with seals which permit a limited range of friction-free displacer piston movement for allowing a starting perturbation of displacer piston position. The seal is a sealing ring resiliently mounted to one of two slidably engaged members of the Stirling engine with a limited freedom of movement relative to that member and sealingly slidable along the other member.
Claims14
A self-starting, free piston Stirling cycle engine having a housing enclosing a work space and a second space which are separated by a power piston reciprocally mounted in a cylinder and further having a displacer piston slidable in a displacer cylinder, the displacer piston having an attached displacer rod means slidably mounted to a bore means communicating between said work space and said second space, wherein the improvement comprises a first seal member sealingly slidable along one of said means and resiliently attached to the other of said means by a resilient support which permits limited, nonfrictional movement of said seal member relative to the means to which it is attached.
