PATENT OFFICE.

Most internal combustion engines have fuel inlet devices in addition to them special devices that make it easier to start the machines, that when the charge is compressed in the cylinder, some of them escape again so that the whole load does not have to be compressed.

These ventilation devices must be used both before the machine is started as well as afterwards, especially by hand, what the operation makes such a machine cumbersome. In addition, the cooling water pipe must be used when starting are also specially opened.

Devices are now known in which the fuel supply is also used the cooling water supply is changed at the same time; with these, however, it can be with the appropriate Action of the control on the cooling water valve happen that after shutdown the engine, the cooling water inlet remains open, so that the cooling water is uselessly lost.

The object of the present invention now aims to connect the Fuel inlet device with the so-called vent valve and the cooling water inlet valve in such a way that these three mentioned locking devices are controlled by one and the same handle. The handle that immediately moves the fuel inlet cock sets that too Vent valve and the cooling water valve in action so that when the fuel tap is closed, so when the engine is at a standstill, also vent valve and Cooling water valve are closed.

When the handle is turned to the starting position, both the fuel inlet cock opens as well as the vent valve; in order to let part of the charge escape again, this is done at the same time Cooling water valve open. After commissioning, turning back the Handle the fuel supply reduced, because for quick start-up a little more fuel was required and the vent valve closes automatically, so that the prime mover now works fully.

In the embodiment shown in the drawing, the fuel tap is Set up for both petrol and petroleum approval. However, it can also Spirit and the others commonly used in explosion and internal combustion engines Fuels such as gas and the like are used. If the operation is to be carried out with gas, a gas tap with a correspondingly larger through opening must be provided. In the illustrated embodiment, the engine can after warming up by gasoline operation during the course can be switched to petroleum operation by turning the handle further.

On the accompanying drawing, Fig. 1 is a vertical longitudinal section through the united Starting and cooling water inlet device, Fig. 2 is a horizontal section through the tap housing, Fig. 3 is a cross section

through the front part of the tap along line i-i of Fig. ι through the Petroleurrizulaßbohrung. Fig. 4 shows a side view of the faucet housing, on the inlet side. Fig. 5 is a front view with the scale board and the pointer handle. Fig. 6 is a cross section through the valve stem ■ and vent valve according to line 2-2 of Fig. I. By means of the handle D ₁ , which ends in a pointer D ₂ and plays in front of the fixed scale board with the inscriptions "Petrol" and "Petrol", the stopcock A _{1 of} the fuel inlet cock A is turned. This cock plug A ₁ is provided with two channels, the petrol passage B and the petroleum passage C, through which on the one hand the petrol inlet B _{1 is} connected to the petrol outlet B ₂ and on the other hand the petroleum inlet C _{1 is} connected to the petroleum outlet C ₂ . The petrol outlet B ₂ and the petroleum _{outlet C 2} direct the fuel to the intake valve of the engine, not shown in the drawing. In order to prevent the passage openings from changing significantly with a small rotation of the cock plug A ₁ , the channels of the cock plug A ₁ open out on the inlet side into the fine slots C ₃ and Β _Ά , which are at the triangular shaped Pass openings B ₁ and C ₁ . The passage opening changes much less quickly with the same rotation of the plug than would happen with an ordinary valve. Behind the inlet tap A ₁ , the vent valve F (Fig. I, 2 and 6) is arranged, which is also controlled _{by the handle D 1} by means of the ring Jp ₁ seated on the plug spindle and provided with the thumb F _2. The purpose of this valve is to allow part of the charge in the cylinder _{to escape through channel F 8} , which is in communication with the interior of the cylinder, and channel F ₁ to the exhaust, so that the charge is less compressed when the engine is started will. The valve F is held open by the thumb F ₂ pressing on the valve spindle. When the engine is started up, the cooling water supply should not be specially operated either. It is therefore by means of the on the cock locker! seated thumb ring F _1, the spindle G of the cooling water _{valve G 1} inevitably coupled with the cock plug, so that the movement of the valve spindle G is dependent on _{the movement of the handle D 1.} As soon as the inlet valve for the fuel liquid is opened by turning the handle D _{1 , the cooling water valve G 1} is also opened. The cooling water flows through the supply line G ₂ and the line G ₃ after the cylinder. The amount of cooling water flowing in is regulated by an ordinary throttle arrangement K. When the engine is at a standstill, the cooling water _{inlet valve G 1} and the vent valve F are closed, as is the gasoline feed B ₁ and the petroleum feed C ₁ . If the engine is now to be started, the pointer D _{2 is set} to the label "gasoline" on the scale. This opens the gasoline duct B completely. The petroleum channel C remains closed. At the same time, the thumb F ₃ presses the valve spindle of the vent valve F down and opens this valve. With the rotation of the pointer D ₂ , the cooling water _{valve G 1} is also opened in that the valve spindle G is equipped with a flat thread, which moves in the corresponding nut thread of the valve housing when the spindle is rotated. Here, the valve disk is lifted from its seat. Instead of a valve being used here, a tap arrangement can of course also be used as a closing means for the cooling water supply, which is then also inevitably to be made dependent on _{the movement of the g 0} tap A _1. If the engine is now in motion, then by turning back the handle D _1, the fuel flow is reduced to the normal supply quantity. The thumb F ₂ releases the valve F , which is closed by the counter spring F ₅ (see FIGS. 1 and 6). If the carburetor is sufficiently warmed up, the handle D ₁ is turned further until the label "Petrol". This closes the gasoline channel B and opens the inflow channel for petroleum. Before the fuel liquids enter the associated channels of the cock plug A ₁ , they go through the cleaning _{filters J3 4} and C ₄ , as can be seen from FIG. The combined starting and cooling water inlet device characterized above can be used for all explosion engines. Of course, you will adapt in n ₀ terms of structure, the respective uses. Godparents τ-Α ν Proverbs: i. Combined starting and cooling water inlet device for explosion engines, characterized in that the fuel inlet device (A), a vent valve (F) and the cooling water inlet device (G ₁ ) are connected to one another in such a way that they are controlled by a single handle (D ₁ ) are in such a way that when the fuel inlet device (A) is opened, the cooling water valve (G ₁ ) is inevitably opened, while the vent valve (F) remains open by this forward position of the handle (D ₁ ) only until the machine is in the correct idle mode , while turning the handle (D ₁ ) for the purpose of switching "to the fuel supply the vent valve is allowed to close automatically. 2. Embodiment of the device according to claim i, characterized in that the control element for the vent valve which is dependent on the handle (D ₁ ) is at the same time a coupling member for the spindle (G) of the cooling water inlet valve (G ₁ ) .
