Abstract: A swash-plate transmission drive system including a rotary driven shaft, reciprocally movable drive shafts, a swash plate secured on said driven shaft, and sliding members, each having a flat surface engaging said plate and a spherical surface engaging one of said drive shafts.

Abstract: Means are provided to enable the main water pump of a Stirling engine to act as a mini-pump to cool the roll sock seals or rolling diaphragms when the engine is not running.

Abstract: A hydraulic brake force-multiplying device includes a body, an output member fitted slidably in the body, a working chamber defined between the output member and the body, a pressure chamber defined in the body and receiving pressure fluid introduced from a source of pressure fluid, a valve seat member positioned in the pressure chamber and urged against the body under fluid pressure of the pressure chamber, a rod member provided integrally with the valve seat member and extending to the interior of the working chamber, a guide bore extending through the rod member axially, a valve stem having a valve portion adapted to cooperate with a valve seat of the valve seat member, thereby forming a valve mechanism in combination with the valve seat, and being sealingly and slidably fitted in the guide bore, an input shaft provided in the body adjacent to one end of the valve stem remote from the working chamber, an intermediate chamber defined between the input shaft and the valve stem and adapted to be communicated

Abstract: An external combustion engine, such as the vapor cycle engine, produces power by the expansion of a working fluid vapor. A vapor generator vaporizes a suitable working fluid which is fed to an expander. The vaporized working fluid expands and is subsequently fed back to the vapor generator. A burner provides energy for the vapor generator. The fuel and air supply for the burner is controlled by a system responsive to operating conditions of the engine. That is, the power input to the vapor generator is correlated by a control system with the demand on the engine. The control system disclosed involves a servomechanism which may suitably respond, for example, to either the working fluid flow rate or the input from an accelerator which commands a change in the working fluid flow rate.

Abstract: A method and apparatus for generating power by passing a motivating fluid from a higher energy level to a lower energy level by compressing said fluid within a centrifuge type first rotor and discharging said fluid via nozzles near the first rotor periphery forwardly in the direction of rotation to a second rotor which is an inward flow type reaction turbine, then passing said fluid through a regeneration type heat exchanger to transfer heat from the inward bound fluid into outward bound fluid, after which the fluid is cooled in a heat exchanger to its original temperature and is passed outward again thus completing its cycle. Heat is added to said fluid near the periphery of the second rotor, or the heat may be added near the periphery of the first rotor, or both. Additionally, the fluid may be supplied to the unit from outside source, and returned to such outside source, and the cooling thus may be eliminated from the unit. Further, the entering fluid from outside source may be at an elevated pressure.
