A device and method for equalizing the pressure between work-space and crankcase in a pressurized engine, such as a Stirling engine. The device consists of a two-way valve connected between the work-space and the crankcase. The valve is connected to the work-space with a passageway including a constriction to provide an mean pressure for monitoring purposes. The valve connects the work-space and crankcase allowing the pressure to equalize when the mean pressure of the work-space exceeds the crankcase pressure by a predetermined amount.
We claim: 1. In an engine of the type having a working space, characterized by a mean pressure, and a sealed crankcase, characterized by a crankcase pressure, an improvement comprising a valve in fluid communication with both the working space and the crankcase, the valve permitting fluid flow between the working space and the crankcase when an absolute value of a difference between the mean working space pressure and the crankcase pressure exceeds a specified value. 2. A device according to claim 1 wherein the engine is a Stirling cycle engine. 3. ...
