Abstract

The invention relates to a technique of ventilation. The purpose of the invention is to increase the reliability of the bench tests of internal combustion engines. A retractable trolley (OT) with a spring-loaded chain is installed on the rails. The air duct (B) 1 and the exhaust pipe (VP) 3, communicated with it, are installed vertically. VP 3 is fixed on OT and placed under B 1. The locking member located in B 1 is made in the form of a butterfly valve 7 with a counterweight 8. On B 1, from the outside, the toothed sector 10 is attached to the axis and interacts with the chain 6. On the inside In 1, a latch 11 of the closed position of the shutter 7 is installed. When the VP 3 is moved by the OT from the working area to the side, the sector 10 turns into rotation and turns the shutter 7 to the closed position. 3 il. a Ш (Л с: /// 1 4 th fiv, 1

The invention relates to devices for ventilation of industrial premises and is intended to remove exhaust gases from internal combustion engines in the gas outlet of the dry-gas installations of test stations with large-sized ducts.

The purpose of the invention is to increase the reliability of work during bench tests of internal combustion engines. On. figure 1 shows the device dp. removal of exhaust gases from internal combustion engines with an open damper, general view; figure 2 - the same, with allotted VE11klaus pipe; on fig.Z - the same, top view.

A device for removing exhaust gases from internal combustion engines comprises a gas exhaust duct 1 with a shut-off member 2 located therein and an exhaust manifold 3 connected to the air duct 1 mounted for horizontal movement. The device additionally contains rails 4 and a retractable trolley 5 mounted on them, equipped with a spring-loaded chain 6, the air duct and the branch pipe are installed vertically, the last one is fixed on the trolley 5 and placed under the air duct 1, the shut-off member 2 is made in the form of a butterfly valve 7 with a counterweight 8 and an axis 9, and the air duct from the outer side is provided with an axial sector 10 fixed on the axis and interacting with the chain 6, the internal ax, with the latch 11 of the closed position of the flap 7.

To guarantee the interaction of the toothed sector 10 with the chain 6, the bar 12 with the springs 13 serves.

The device works as follows.

For the period of assembly-demolition of the test product, for example, an internal combustion engine, exhaust pipe 3, mounted on a retractable carriage 5, moved along the rails 4 by means of an actuator (not shown) or manually, moving the station from its working area to the side parallel to its own axis. In this sector 10, on42072

Coming in conjunction with a chain 6, mounted on a sliding carriage 5, due to its movement it turns into a rotation and turns horizontal

5 axis 9 and flap 7 in the closed position.

The counterweight 8, fastened on the flap 7 when it is removed from the vertical position, at the same time, the method 0 ensures its guaranteed rotation to the horizontal position. The latch 11 fixes the horizontal position of the flap, ensuring reliable overlap of the stationary part of the air supply from the outside air flow into the room.

During the reverse movement of the cart 5, you: cotton nozzle 3 returns, connected to the gas exhaust air. At the same time, sector 10 rotates in the opposite direction, turning the flap 7 to the vertical position Open. Vent is ready for
