Embodiment Construction
[0029] The Stirling engine assembly comprises a Stirling engine 1, which is well known in the art. The Stirling engine has a displacer and a power piston, both arranged to reciprocate in a vertical direction. This produces a net vertical vibration of the Stirling engine 1 itself.
[0030] In order to reduce this vibration, the damper mass 2 is supported by compression springs 3 above and below the damper mass 2 . This structure is housed in a casing 4 which is rigidly fixed to the bottom of the Stirling engine 1 . The mass 2 and spring 3 are adjusted such that the damper mass 2 vibrates as closely as possible in anti-phase to the Stirling engine 1 when the Stirling engine 1 is operating at the normal operating frequency. Thus, the overall vibration of the Stirling engine 1 and housing 4 is greatly reduced.
[0031] The current structure includes 8 compression springs 3 above and 8 compression springs 3 below the shock absorber mass 2 of 10.5 kg (±10%). For example, these s...
