Embodiment Construction

[0027] See Figure 1 first. A steam-vacuum engine, referenced 10, includes a first cylinder 12 on the left and a second cylinder 14 on the right. The first cylinder 12 has a first piston 16 and a first piston connecting rod 18 . The first piston 16 is movable between an expansion position B and a compression position A, the first piston defining a movable boundary of a first vapor chamber 24 in the first cylinder 12 . The second cylinder 14 similarly has a second piston 30 and a second piston connecting rod 32 . The second piston 30, which defines the movable boundary of the second vapor chamber 38 in the second cylinder 14, is movable between an expansion position B' and a compression position A'.

[0028] In the illustrated embodiment, a link 40 connects the first and second piston rods 18, 32 such that the first and second pistons 16, 30 move synchronously in a linear connection. It is easy to understand that there are many feasible ways to connect the piston rods in the ...

Abstract

The invention relates to a two-stroke steam-vacuum engine comprising a plurality of cylinders (500, 502), each cylinder having a piston (504, 510), a piston connecting rod (506, 512) and a steam chamber (508, 514) , connecting the piston rods for synchronous movement so that each piston reciprocates between an expanded position and a compressed position. Allow steam 3-5 p.s.i higher than atmospheric pressure to enter the steam chamber (508, 514) controlled by the steam valve (522, 524), and open the steam chamber to make it a vacuum state by the vacuum valve (548, 550) . The steam supplied to the steam chambers (24, 38) may be generated by a boiler (520), a solar device or other optional fuel. An auxiliary vacuum box (572) may be isolated from the main vacuum box (554) for providing vacuum after condensate collection box (560) removes condensate. Auxiliary vacuum pumps (614, 616) powered by cylinders (500, 502) provide vacuum to auxiliary vacuum box (572), while main vacuum pump (570) provides vacuum to main vacuum box (554).

Description

technical field [0001] The invention relates to a steam engine, in particular to a steam engine in which the steam in the steam chamber of the cylinder is in a vacuum state when the pressure is from atmospheric pressure to slightly higher than the atmospheric pressure to generate a power stroke. In particular, the steam vacuum engine involved in the present invention has two or more cylinders with connected pistons, each cylinder has a steam chamber, which can accommodate steam at atmospheric pressure or slightly higher than atmospheric pressure, and the steam is discharged from the cylinder to cause the cylinder The vacuum in the cylinder allows the ambient air back pressure to push one of the connected pistons through the power stroke. Background technique [0002] The development of modern steam power began with Thomas Savery patenting the Savery pump in 1698, which was used to remove water from mines. The pump heats water to generate steam, feeds the steam into a contai...
