The invention relates to the field of armored vehicles, in particular to the device power supply system air tank engine.

The known device: system supply of air to the engine tank. 434 /see the Object 434. Technical description and operating instructions. The second book); the scientific research Institute of Information, 1974. S. 282-284/; system clean the tank about. 219 /see the Object 219. Technical description and operating instructions. The second book. M , Voenizdat 1979, S. 163-165/; system air supply tank T-62 /Guide material and operation of the T-62 /Guide material and operation of the T-62 tank. M, Voenizdat. 1968, S. 282-283/.

These devices represent the FDS is eh. A significant drawback of the above structures is the inability to delay water entering the engine scuba driving or for other reasons /crossing mountain rivers, rainfall, violation of service technologies and so on/. This leads to dangerous malfunction and accidents tank engines.

Of the analogues studied as a prototype individual system of air cleaning tank about. 219, (see "Object 219 Technical description and operating instructions". The second book. M, Voenizdat, S. 163-165) containing air intake louvers, housing, transition compartment with flange and pipe collecting dust.

In a combat situation and conditions of use of tanks in peacetime, the main type of fording tank groups is crossing under water. When the tank is in a submerged state for various reasons (combat damage, depressurization of the machine through the fault of the personnel and so on ) are often cases of water ingress into the tank. As for underwater driving the air intake for the engine is carried out directly from the internal volume, the water can get into the air cleaning systems. Unobstructed ingress VM image, the existing system of air cleaning do not protect the motor from water damage, which is a significant disadvantage.

The objective of the proposed technical solutions to protect the motor from water hammer when the water inside the tank.

This task is achieved by the fact that in the device to protect the tank engine from water hammer, containing air intake louvers, housing, transition compartment with flange and pipe collecting dust, optionally in the transition compartment made a hole, through which the adapter is installed the sensor the presence of water having an electrical connection through the amplifier mechanism stop engine light and sound alarms.

The proposed device is illustrated by a drawing.

The device includes a housing 1, a transition compartment 2, the batteries of cyclones 3, the nozzles suction dust 4, a sensor 5, the mechanism for stopping the engine 6, the amplifier 7, the bracket 8, the electric light bulb 9, the audio signal 10, the flange 11, the intake louvers 12, technological hole 13, the adapter 14.

The proposed device is as follows.

a) In the absence of water in the transmission.

Untreated air is drawn works the same compartment 2 enters the engine. The sensor 5 is always dry and the signal at the output of amplifier 7 is missing. The electromagnet mechanism for stopping the motor 6 is deenergized, the tank engine works.

b) If water in the tank.

Water with untreated air enters the battery of cyclones 3 and, being heavier than air, immediately settles to the bottom of the transition compartment 2 and fills the sensor 5 before the level reaches the height of the collar flange 11 When the water touches the sensor 5 varies its resistance in the direction of decreasing, i.e., an electric signal circuit: sensor 5 to the amplifier 7. The amplifier 7 amplifies the signal and feeds the electromagnet mechanism stopping the engine 6, which kills the engine. Because the engine is suppressed before it rises above the water level in the transition compartment 2 clamp transition flange, the water will not have time to get into the engine and thus the engine is protected from water hammer.

The proposed system of air cleaning tank will protect the motor from water hammer when the water inside the tank for various reasons.

The simplicity of the device and the use of commercially available parts, assemblies and devices will allow you to easily and quickly the STV to protect the tank engine from water hammer, contains intake louvers, housing, transition compartment with flange and pipe collecting dust, characterized in that in the transition compartment made a hole, through which the adapter is installed the sensor the presence of water having an electrical connection through the amplifier mechanism stop engine light and sound alarms.
