In-clined′--cyl′in-der steam-en′gine.
A form of
direct-action steam-engine, in which two cylinders are placed in a frame so as to work at an angle to each other, the connecting rods giving motion to the same crank.
It was invented by
Brunel, and patented by him in 1822.
|
Brunel's inclined-cylinder steam-engine. |
a a is a strong triangular frame of cast-iron, within which are fixed the two cylinders
b b.
Mr. Brunel preferred that the angle formed by the axes of the cylinders should be 102°.
d d are the connecting rods attached to the crank
e, which gives motion to the paddle-shaft.
The piston-rods are supported upon rollers, which traverse on guide-plates to preserve their parallel motion during the stroke.
In the small cylinders
g g are piston-valves by which the steam from the boiler is admitted to the alternate ends of the cylinder and allowed to escape from the other end. The action of the piston-valve is regulated by the eccentrics on the paddle-shaft.
These eccentrics give motion to the rods
h h, which, by intermediate levers, operate upon the pistons in the small cylinder.
This is one of the numerous devices intended to obviate the use of the beam in marine engines.
