Hydraulic heat engine |
| abstract |
An hydraulic heat engine having an upright cylinder with a first conduit thereto for introducing liquid, for example sea water, into the cylinder in which the liquid is in effect a piston leaving an expansion chamber space at the upper end of the cylinder into which propellant such as hot expanding gaseous media or a fuel mixture which expands upon combustion is introduced through a second conduit to expand and propel the liquid piston down and out through a third conduit from a lower part of the cylinder. This third conduit transmits the propelled liquid to a first transfer chamber to move a first piston therein mounted fast on a piston rod connected to rotatably drive an output shaft. The return stroke of the piston rod moves a second piston mounted fast thereon in a second transfer chamber to push a fresh supply of liquid therefrom into the second conduit for admittance to the cylinder. Additional conduits are provided to admit fluid from a supply to the second transfer chamber during the second piston''s down stroke and to exhaust the fluid from the first transfer chamber during the first piston''s return stroke. A control device such as a cam arrangement driven by the output shaft controls valving in the conduits to regulate the supply of expansible propellant and the flow of liquid during the operating cycle. |
