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.

Dependent claims

A thermal hydro-machine for conversion of heat energy into mechanical work comprising:

(a) a first assembly comprising:
(i) a rotational heat exchanger comprising a set of interconnected segment collectors arranged in the form of a cylinder's shell, wherein the interconnected segment collectors are capable of receiving heat and are capable of delivering heat depending on the position of the segment collectors relative to a heat source or cooled space when a compressible medium or working gas is under pressure;
(ii) a set of working segment cylinders with free pistons or a set of working segment chambers with an elastic membrane, wherein said set of working segment cylinders with free pistons or said set of working segment chambers with an elastic membrane are connected and functionally paired with said segment collectors, and wherein when said compressible medium or said working gas is under pressure the compressible medium or the working gas fills the set of working segment cylinders with free pistons or the set of working segment chambers and it fills said segment collectors;
(iii) directed narrowed-down curved channels that directly connect said working segment cylinders or said working segment chambers with a working vane wheel, thereby directing and accelerating an incompressible medium or liquid in a concentrated way toward the center of said working vane wheel;
(iv) return widening curved channels for the recirculation of said incompressible medium or liquid, wherein said return widening curved channels are directly connected with said directed channels and with said working vane wheel;
(v) return widening curved channels for abstracting said incompressible medium or liquid, wherein said return widening curved channels are directly connected with said working segment cylinders or with said working segment chambers and are directly connected with said working vane wheel;
(vi) arch wise mobile vanes for closing and opening of said return widening curved channels for abstracting of said incompressible medium or liquid, or axially mobile closers with the capability for a two-direction axial motion for the closing and opening of an exit of said return widening curved channels for abstracting of said incompressible medium or liquid, which are firmly fastened on the free pistons in said segment cylinders or on the mobile elastic membranes in said segment chambers;
and
(vii) inserted transmitter on a casing of said first assembly;
(b) a second assembly comprising:
(i) a working shaft that is freely embedded on said casing of said first assembly and a machine stand, wherein said working vane wheel is firmly fastened or wedged on said working shaft and wherein a hydrodynamic flow energy of said incompressible medium or liquid converts into the rotational mechanical work;
(ii) a driving transmitter of the relative motion, wherein the driving transmitter is firmly fastened or wedged on said working shaft and coupled with a driven pair of intermediate transmitters;
and
(iii) a generator's rotor that is firmly fastened or wedged on said working shaft;
and
(c) a third assembly comprising:
(i) said driven pair of intermediate transmitters, wherein said driven pair of intermediate transmitters are placed coaxially with respect to said working shaft and freely embedded on the shaft of an embracing carrier;
(ii) said embracing carrier, wherein said embracing carrier is freely embedded on said machine stand;
and
(iii) said machine stand to which the casing or a stator of said generator is firmly fastened.
