Embodiment Construction

[0017] In the following description, numerous details are set forth in order to enable an understanding of the present disclosure. However, it will be understood by those skilled in the art that the described embodiments may be practiced without these specific details. Furthermore, many variations or modifications may be employed which are still contemplated by the specifically described embodiments. For example, embodiments herein are described with reference to diagrams depicting certain floating double-headed piston assembly systems or engines. However, by incorporating additional piston assemblies, a number of additional valve controllers or timing controllers, etc., various arrangements can be used. However, these system / engine layouts are merely illustrative, as various hydraulic or even mechanical layouts and other designs may be used depending on system constraints and intended application.

[0018] Embodiments detailed herein may use controlled expansion and contrac...

Abstract

An assembly with a piston reciprocated with the aid of a floating head in fluid communication with the piston. The assembly may utilize a floating head that is shifted in position to promote reciprocation of the piston through the aid of pressure supplied to the floating head from a pressure volume regulator. Alternatively, the floating head may be in fluid communication with the piston at one side of the head and isolated at the other side. In this manner changing volume and pressure at this other side of the head during reciprocation may ultimately lead to floating head movement toward the piston, thereby promoting the continued reciprocation. Additional efficiencies may also be realized through unique hydraulic layouts for both operating and working fluid circulations.

Description

Background technique [0001] Over the years, various efforts have been made to gain power through different thermodynamic cycles. For example, technologies have been developed to generate electricity from devices that rely on the "Brayton", "Stirling" or "Organic Rankine" cycles (ORC). Unfortunately, these techniques are generally ineffective and inefficient with low temperature heat sources, eg, below the boiling point of water. [0002] For example, ORC equipment or engine manufacturers often offer a system that allows practical operation at input heat temperatures as low as 170°F. However, it turns out that this can only be allowed if a significantly reduced output is also obtained, thus making the task considerably less economical. In part, this is due to the fact that the method of operation uses two phase transitions per cycle, from liquid to gas and back to liquid, and uses a turbine or turbine-like technology to convert gas to gas The power is converted into generati...
