Abstract
A Stirling engine assembly for a DCHP system. A Stirling engine (1) is suspended from a mounting frame (5) by a plurality of tension springs (6). An annular absorber mass (2) surrounds the Stirling engine and is suspended from the engine on a plurality of resilient members (3) arranged asymmetrically about the main axis. The asymmetric arrangement is provided by members of different stiffnesses, or irregular spacing of the members. The absorber mass (2) itself may be reduced adjacent to the resilient members.
Claims22
A Stirling engine assembly comprising a Stirling engine, a mounting frame on which the engine is mounted so that the axis along which the reciprocating components reciprocate is vertical, in use, the engine being hung from the mounting frame by a plurality of tension springs.
A Stirling engine assembly comprising a Stirling engine, a mounting frame on which the engine is mounted so that the axis along which the reciprocating components reciprocate is vertical, in use, wherein an annular absorption mass surrounds the Stirling engine and is suspended from the engine on a plurality of resilient members, to provide an anti-phase force to the engine, the resilient members being arranged asymmetrically about the main axis of the annular member.
