    Abstract: An externally heated engine is provided which has a piston and a displacer. The position of the piston can be adjusted by a yoke and disk assembly on one end of a link and spacers and gaskets in the cylinder. The relative position of the displacer with respect to the piston can be changed by changing the relative position of a pair of disks in the crankshaft assembly. The displacer is caused to reciprocate by a link which is moved by a displacer cam assembly. The displacer cam assembly includes a first cam and a second cam. The first cam and the second cam each have a groove path. The displacer link follows the groove path of the cams to cause the displacer to dwell at the two ends of its stroke and to move rapidly from one end to the other.

    Abstract: A thermal hydro-machine on hot gas with recirculation (FIGS. 3, 4 and 5) belongs to the group of multi-cylinder piston rotational machines for converting the heat into the mechanical work. The heat is conducted to on the outer side of one part of rotational tubular heat exchanger (1) and is simultaneously conducted away from the other part of same exchanger (1). The exchanger is composed of a set of independent segment collectors (1) arranged in the form of a cylindrical shell, made pair wise with a set of independent segment cylinders with free pistons (2) in which there is the independent gas under pressure.

    Abstract: An improved, free-piston, Stirling machine having at least three pistons series connected in an alpha Stirling configuration. Each cylinder is stepped so that it has a relatively larger diameter interior wall and a coaxial, relatively smaller diameter interior wall. Each piston is also stepped so that it has a first component piston having an end face facing in one axial direction and matingly reciprocatable in the smaller diameter cylinder wall and a second component piston having an end face facing in the same axial direction and matingly reciprocatable in the larger diameter, cylinder wall. One of the piston end faces bounds the compression space and the other end face bounds the expansion space. Preferably, each stepped piston has peripheral, cylinder walls that are axially adjacent and joined at a shoulder forming the end face of the larger diameter component piston. Stirling machines with these stepped features are also arranged in various opposed and duplex configurations, including arrangements with only one load or prime mover for each opposed pair of pistons. Improved balancing or vibration reduction is obtained by connecting expansion and compression spaces of a four cylinder in-line arrangement in a 1, 3, 2, 4 series sequence. Three cylinder embodiments provide a highly favorable volume phase angle of 120° and are advantageously physically arranged with three, parallel, longitudinal axes of reciprocation at the apexes of an equilateral triangle.

    Abstract: A stirling engine includes a flow path which communicates a working space of the stirling engine and a crankcase of the stirling engine. An output of the stirling engine is controlled so that the output lowers when a pressure inside the working space is higher than a pressure in the crankcase, with a transfer of a fluid in the working space to the crankcase via the flow path thereby causing a decrease in the pressure of the working space.

    Abstract: A Stirling cycle engine of a simplified structure, having enhanced reliability by improving abrasion resistance and lubricity of components thereof. When a piston reciprocates in a cylinder along the axial direction thereof by a driving mechanism, a displacer reciprocates in the cylinder along the axial direction thereof accompanying the reciprocation of the piston. The piston and the displacer slide in contact with the inner peripheral surface of the cylinder, but the piston and the displacer are each integrally made from an engineering plastic such as PPS having fine strength, dimensional stability, abrasion resistance and formability, while PPS is made CFRP. Moreover, solid lubricity agent is added to PPS. Accordingly, abrasion resistance, lubricity, strength and precision of the piston and displacer are enhanced, while the piston and the displacer can be simply produced by a well-known plastic molding.
