Felix AMIOT 0586-? 4 ~ B ship with an engine room.

The invention relates to ships with a

Machine room, i.e. a (generally in the form of a dense; Department trained) special room, which the propulsion system of the ship, certain auxiliary machines (e.g. power generation units), as well as a control station for the monitoring and the operation of the drive systems and auxiliary machines entrusted personnel, this control station has all measuring and remote control systems, which the staff allow his task of monitoring and operation to perform

The invention relates in particular, if not exclusively, to the tendon 11b ο ο te j of such ships. in particular the military speedboats for offensive or defensive undertones at sea during which there is a risk of that they get a direct hit, v / elcher a leak in

! forms and is provided with at least one exhaust silencer, which rests on the side wall of the fuselage and is strong the water taken from the surrounding water mass is cooled, with the removal of the gases cooled in this way below the water line he follows.

Any exhaust silencer can be useful be formed by a kind of box, the length of which is considerably greater than its width, and which contains the following parts:

- Above a collecting pipe for the supply of the hot

Exhaust gas, which consists of a porous material and inside with a liquid from the surrounding water mass supplied atomizing tube is provided;

- at different heights baffles and

porous barriers, which are sprinkled with liquid from atomizing tubes supplied with liquid from the surrounding water mass bej

- And below a collecting pipe for the discharge of the cooled exhaust gases, which is outside the ship's hull and flows below the waterline.

Preferably at least some of these

Inlet collecting pipes, baffles and porous barriers formed by a filter material, e.g. mineral wool. _:

According to a preferred embodiment of the 'different measures above the engine room of the ship according to the invention contains:

- A main propulsion system, which by two

independent drive units is formed (each of which drives its own screw), which are arranged symmetrically in relation to a central aisle on port or starboard, with each drive unit suitably by two one above the other; lying layers of horizontal opposing cylinders ^{: is} formed, which are associated with a common, rear-lying reduction gear, the output shaft of which with the; corresponding screw is coupled 5

- two operating power generating units, which are symmetrically on port "and starboard via the reduction gears of the two drive units in the immediate Are located near the operator's cabin;

- an emergency power generator, which is in

the axis of the ship at the level of the engine room floor behind the operator's cabin;

- Control panels assigned to the power generation units (operating unit and emergency unit), which are listed under the operator's cabin;

- and two exhaust silencers in which

the gases are strongly cooled (so that they do not emit any infrared j rays), and which are symmetrical on port or j Starboard on the side walls of the engine room one of each! two drive units / are arranged, this sound-> damper by separate circles on the one on the same side; horizontal drive unit and power generation unit attached to j

The various power generating sets [

preferably have opposite cylinders with the same \ dimensions as the cylinder of the drive units of the Hauptan-! drive arrangement so that replacement parts are limited to a single type of pistons, connecting rods, cylinder heads, etc.

The invention is hereinafter referred to explained on the drawing by way of example.
