ABSTRACT:
In a vibration-reducing apparatus for a direct-acting type stirling engine, a change of pressure caused by the reciprocal movement of a displacer is applied to a power piston to produce a mechanical force, and the mechanical force is converted into an electric power by a direct-acting type electric generator which is directly connected to the power piston so as to effect reciprocating movements with the power piston. Such apparatus comprises a vibration-controlling actuator fixed to a cylinder to produce a vibration-controlling force in response to a drive-controlling signal given by the outside thereof, a detector for detecting an unbalanced movement by a force of inertia in the reciprocating movements of a direct-driving part consisting of the power piston and the direct-acting type electric generator, and a control circuit for receiving a detection signal from the detector to control the vibration-controlling actuator so that the vibration-controlling force of the vibration-controlling actuator cancels the unbalanced movement by the force of inertia caused by the reciprocating movements of the direct driving part.
