Description

: ., ,, one

The invention relates to electrical engineering, in particular to spark plugs adapted to observe the combustion process in the cylinders of internal combustion engines.

The aim of the invention is to improve the extruded properties of the tube by increasing the convenience of observing the combustion process.

FIG. 1 shows a candlestick-indicator indicator, a longitudinal section; in fig. 2 - the upper part of the tube, a longitudinal section.

The indicator candlestick tube contains a hollow body 1, at its 1 end 2 which has a hex socket 3 for the candle indicator, a screen with a mirror 5 is installed at the upper end 4, and contact 6c is fixed in the middle part with a conductor 7.

The screen is made in the form of a U-shaped bracket 8, the middle part 9 of which is made flat, a; the bent ends 10 are installed parallel to the axis of the body 1 and are provided with elastic ball segments 11. The upper end 4 of the body 1 is filled with a spherical one. The mirror 5 is installed between the bent ends 10 of the U-shaped bracket 8 on its flat middle part 9. The width of the bent ends 10 of the bracket 8 is made equal to

the width of the mirror 5. To supply high voltage to the indicator candle in the middle part of the body, a tide 12 is made with an opening 13 for mounting

5 of the conductor 7, consisting of a metal needle 14, welded to contact 6, a high-voltage insulated wire 15, a tip 16 and a pin 17. A wire 15 is installed between

 needle 14 and tip 16.

The proposed device operates as follows. .

The tube with the lower end 2 with the hexagon socket 3 is put on the hex of the indicator candle having a transparent central part (not shown). The high-voltage wire of the engine ignition system is connected to the tip 16 of the conductor 7, after which the engine is started. The U-shaped bracket 8 of the tube is installed in a position convenient for observing the combustion process in the engine cylinder through the transparent central part of the indicator candlestick.

The proposed candle tube indicator increases the convenience of studying the process of the internal combustion engine due to a greater degree

30 of the mirror mounted on the U-shaped bracket of the tube, and thereby reduces the time of the study.
