摘要： A control valve for a double acting type Stirling engine of the type having two or more piston assemblies reciprocating in bores with each of the piston assemblies separating isolated volumes of a working gas. The control valve provides the functions of a check valve which allows an internally defined volume within the engine to be held at a low pressure near the minimum pressure of the cycle volumes. The valve may further be actuated to unload the engine to provide low starting torque and to unload the engine in case of an engine or load malfunction. The control valve further provides a controlled leakage path for working fluid flowing between the cycle volumes and the minimum pressure volume which acts as part of a pressure balancing system for the Stirling engine which maintains the volume or mass of a working fluid in a balanced condition between the cycle volumes.

摘要： A working gas control system for a double acting type Stirling engine having two or more piston assemblies reciprocating within bores. Each of the piston assemblies separate isolated cycle volumes of a working gas which undergoes cyclical pressure variations. The pressure equalization system includes forming isolated first and second volumes with the first volume maintained at a low pressure through the use of a check valve. The second volume is maintained at a pressure intermediate of the minimum and maximum pressures of the cycle volumes. By providing controlled leakage paths between the volumes, the mass or volume of working gas in each of the cycle volumes can be maintained in a balanced condition despite minor leakages outside the engine of the working gas and leakage past the piston assemblies separating the cycle volumes. Additional features further include the provision of a control valve which acts to unload the engine for starting or shut down, and further can provide the functions of a check valve and a control leakage path within the engine.

摘要： A piston assembly for a double-acting engine such as a double-acting Stirling engine. A pair of sealing rings located on opposite sides of a land ring are positioned between a base section and a dome section of a piston head. These sealing rings are alternatively urged into sealing engagement with the cylinder bore as the piston reciprocates. The ring assembly further features selected rings with radial gaps used with annular non-split rings. An expander ring is further provided to radially bias the sealing rings with radial gaps. The piston assembly further features assembly features and component configurations providing excellent piston gas sealing and durability performance.

摘要： A working gas pressure equalization system for a multiple-cylinder, double-acting hot gas engine such as a Stirling engine of the type having a plurality of pistons reciprocatable within the cylinders defining a plurality of generally isolated cycle volumes of a working gas separated by the pistons. The equalization system incorporates passages through the piston connecting rods which connect between a space between piston rings and an equalization volume defined between a pair of sliding rod seals. This volume is defined by portions from each of the cylinders and is connected with individual cycle volumes by a valve, such as a one-way check valve. When a pressure is experienced in one of the cycle volumes different from the minimum pressure maintained and the equalization volume, minute gas leakage across the piston rings enables pressure among the volumes to be equalized.
