Device to avoid the suction of
V7asser by diesel engines

The invention relates to a device for preventing suction
of water from diesel engines in underground mining, for example
in diesel traction trolleys, in which the exhaust gas is passed through an exhaust gas cooling tank filled with water. ; '

By cooling the exhaust gases and avoiding sparks as well as ■ relieving the weather management, it is inevitable that the underground | Gigen mining inserting diesel engines with an exhaust gas cooling to comparable \ see.

If diesel engines suddenly stall, for example on diesel towing trolleys, it has now been shown that the engines were destroyed by water hammers. Motor as a pump and sucks in water from the exhaust gas cooler. In addition | two to three revolutions of the motor are sufficient. The engines are taken out of service and the necessary repairs, for example two the bent connecting rods require a lot of time and money

The object of the invention is to create a device which eliminates the so-called water hammer with exhaust gas cooling containers provided diesel engines and avoids the resulting consequential damage.

This object is achieved according to the invention in that in the exhaust pipe at a small distance from the Abgaskuhlbehalter one in the direction on the exhaust gas cooling container openable non-return valve is arranged.

"It proves to be particularly advantageous that the non-return valve is designed to be pivotable by means of a pivot axis extending above the center point in a horizontal plane.

Furthermore, it proves to be advantageous that the non-return valve above the pivot axis against a seal arranged inside the opening and below the pivot axis against a seal is designed to be closable seal arranged outside the opening to the exhaust gas cooling container.

The technical progress of the invention is essentially therein justifies that by installing a hinge-like pivotable Non-return valve, which lets the exhaust gases through in one direction and blocks the suction of water on the other side, the engine damage originally caused by the water hammer can be completely avoided in a simple manner.

An embodiment of the invention is shown in the drawings and is described in more detail below. Show it:

Fig. 1 is a schematic representation of the exhaust gas routing through an exhaust gas cooling container, partially in section,

Fig. 2 shows a cross section through a non-return valve and

3 shows a side view of an exemplary embodiment of a non-return valve on average,.

As the schematic representation in Fig. 1 shows, the from Diesel engine not shown coming exhaust gases via the hose-like exhaust pipe 1 in the direction of the arrows through the exhaust gas cooling container 2 and led out of this again, the continuation of the exhaust gases behind the exhaust gas cooling container 2 also not shown ..is"

The opening 6 of the exhaust pipe 1 is in front of the entry of the exhaust gases into the exhaust gas cooling container 2, as can be seen from FIGS. 2 and 3 can be closed by a non-return flap 3.

The check valve 3 is only approximately the cross section of the opening 6 adapted. When pivoting the check valve 3 in the direction of the double arrow shown in Fig. 3, the upper part of the Non-return valve 3 against the seal 7 and the lower part of the non-return valve 3 against the seal 8. This arrangement of the non-return valve 3 ensures a passage of the exhaust gases from the exhaust pipe 1 into the exhaust gas cooling container 2 and blocked when through Sudden stalling suction of water in the opposite direction.

The course of the exhaust gases is through within the exhaust gas cooling container 2 Arrows indicated. The exhaust gases are fed into the exhaust gas cooling container 2 in pipe coils 5.

β The above the center point of the non-return valve 3 and that transversely

^The pivot axis 4, which is arranged in relation to the path of the exhaust gases, enables the non-return valve 3 to react immediately to exhaust gas pressure or in the opposite direction when it is sucked in.
