Abstract: Heat exchanger fins and a method for fabricating fins particularly suitable for the head of Stirling engine. The fins have a frusto-conical contour and surround and are brazed to the heater head at axially spaced positions. The inner edges of the fins are rolled to provide a flange for engaging and being joined to the head and have axially aligned, radial slots cut into the outer edge to provide channels for the passage of the products of heater combustion. The fins can be formed of annular rings or from a ribbon bent into a helix.

Abstract: An apparatus for detecting and reducing excessive amplitude of oscillation of a free piston slidably mounted in a housing. The housing has a vibration absorber, including a mass mounted through a spring to the housing. The mass reciprocates relative to the housing along a path in a phase relationship to the piston. A sensor is mounted near the mass for detecting the amplitude of oscillation of the mass. A controller is connected to the sensor for reducing the amplitude of oscillation of the piston when the amplitude of oscillation of the mass reaches a predetermined maximum.

Abstract: A free-piston Stirling engine that limits piston amplitude and reduces engine power as the piston amplitude increases beyond its maximum power. The inward edge of the heat rejecter cylinder port is located outward of the most inward excursion of the inward end of the piston sidewall during a part of the piston's reciprocation cycle so that the heat rejecter cylinder port is entirely covered by the piston sidewall during an inward portion of the piston reciprocation when the engine is operating at the selected maximum engine power. A leaker port extends from a gas bearing cavity through the piston sidewall and is positioned axially outward from the gas bearing pads of the engine's gas bearing system and vents working gas to the engine's back space at a piston amplitude of reciprocation that exceeds the piston's amplitude of reciprocation at maximum engine power. A resilient damping bumper is attached to the outward end of the piston and a displacer gas cushion is disclosed.

Abstract: A flexure bearing "planar" spring that can spring multiple, independently reciprocating bodies, such as springing each body to a third body or springing a first body to a second body and springing the second body to a third body. A primary arm set of primary spring arms are separated from each other by openings and extend inwardly from a peripheral frame along a non-radial primary path progressing inwardly toward a central axis and angularly about the central axis. A secondary arm set of at least one secondary spring arm extends along a non-radial secondary path progressing radially and angularly about the central axis. Each secondary arm is interposed in an opening between the primary arms allowing the primary arms and the secondary arms to pass by each other through the openings without interfering with each other.

Abstract: Multiple free -piston Stirling (FPS) machines are arranged in a group and connected for preventing or minimizing vibration. A first set of identical beta FPS machines are rigidly connected together, arranged in a mechanically co-directional orientation and configured to reciprocate in thermodynamically synchronous reciprocation with each other. The first set has axes of reciprocation intersecting a first point, which may be a point at infinity. The axes of the first FPS machines make the same angle with a central axis of motion and are equi-angularly spaced around the central axis. A second set of beta FPS machines are rigidly connected together and rigidly connected to the first set of machines. The second set of machines are arranged in a mechanically co-directional orientation that is the same as the mechanical orientation of the first set of beta FPS machines. The second set of machines are configured to reciprocate in thermodynamically synchronous reciprocation with each other but in thermodynamically opposed reciprocation to the first set. The FPS machines of the second set are identical to the FPS machines of the first set and have axes of reciprocation intersecting a point, which may be a point at infinity. The axes of the second set of FPS machines all make the same angle with the central axis of motion and are equi-angularly spaced around the central axis of motion.
