ABSTRACT:
A sealing mechanism in a Stirling engine comprising, an output deriving device, a rod for connecting an operating piston defining an operating space and the output deriving device, an intermediate member for supporting the rod in fluid-tight manner via a bush, a sealing member secured to the intermediate member and including a lip in elastic engagement with the rod for assuring a fluid-tight fit, an intermediate chamber defined between the sealing member and the operating piston, a pressure chamber defined between the sealing member and the intermediate member, a first check-valve allowing fluid-flow from the intermediate chamber to the pressure chamber and a relief valve to be opened for releasing the pressure in the pressure chamber into a space for accommodating the output deriving device when the differential pressure exceeds a predetermined value.
