SU74830A1 - Safety device for discharging water from engine cooling systems when it freezes - Google Patents

Description

Safety devices for internal combustion engines that serve to drain water from cooling systems and act on the principle of water spraying as it passes into ice using a spring to open a valve are known.

A distinctive feature of the proposed device is that, in order to more reliably; o open the valve, a drummer is used, released by a hook by means of a plunger, which is affected by water, which disintegrates during freezing.

The proposed device is shown in the drawing.

The device body 1 is attached to the engine cooling system from below. It is provided with channels .2 and. and camera 4, where the main mechanism of the device is located. Channels 2 and 3 are interconnected by camera 5. The upper end of channel 2 and the upper end of channel 3, consisting of a row of tubules 12, are in communication with the engine cooling system.

The filling of chamber 5 with water from the cooling system is carried out through the channels 12 and channel 3, and the air is forced out of it through channel 2.

The canaliculi 12 function as a mesh, protecting channel 3 from being littered.

The chamber 4 is connected to the chamber J by an opening in which the plunger 6 is placed. In the upper part of the chamber 4 there is an opening in which the valve 7 is located, held in the socket by the spring 8.

Near the plunger fi, a hook 9 is connected to the housing / HjapnnpHO, which rests with one shoulder on the go. the plunger 6, and the other is in engagement with the drummer 10. The latter is also pivotally connected to the body with the lower part, and the middle part is connected to the working spring 11, which is attached to the body with its other end.

The operation of the device is as follows.

A safety device attached to the bottom of the water system is automatically filled with water through channels 12 II channel 3. In the case of a decrease in the temperature of the surrounding environment, conditions are created for freezing water in the system and at the same time the safety device; in the channels due to

its small amount and large cooling surface.

Simultaneously freezes water in chamber 5, where the volume of water is relatively small. Freezing and expansion of water in channel 5, not finding another outlet, will push plunger 6. Extended by the pressure of freezing water in chamber 5, plunger 6 will press on the hook of hook 9, which will slide and release spring-loaded hammer to strike the valve stem 7. The latter will the springs // and 10 will rise, break the ice crust formed and release water from the system to the outside. .

In order to re-charge the device, the latter must be removed, and the drummer 10 should be retracted until it is gripped by the hook hook 9. The plunger 6 is then moved into its initial position. The safety device is then reattached.

Prevention and Consideration

A safety device for discharging water from the engine cooling systems when it freezes, acting on the principle of expanding water when it enters the ice, with a spring to open the valve, which is different from that. in order to open loianana more reliably, a drummer was used, released by a hook, by means of a plunger, which is affected by water, expanded usha with during freezing.
