Abstract

PURPOSE:To easily feed fuel by the pressure of air to a carburetor when an engine is started, by providing a priming pump in a fuel route from a tank to a diaphragm chamber while a fuel reservoir chamber, which stores air in its upper part, and compressing the air when the fuel is forced to be fed into the fuel reservoir chamber at priming time. CONSTITUTION:Fuel is supplied from a tank 17 through a priming pump 23, pump chamber 14 and a fuel valve 19 to a carburetor 1 having a diaphragm 18. The fuel in the tank 17 is allowed to flow into a diaphragm chamber 7 through the above described route by actuating the priming pump 23 before an engine is started, but here the fuel, being allowed to flow also into a fuel reservoir chamber 25 initially filled with air and compressing the air, is returned to the tank by opening a check valve 27 if a pressure of the air increases to a predetermined value or more. If the engine is started from this condition, the fuel in the fuel reservoir chamber 25, being forced to be fed by an air layer 24, is surely supplied to the diaphragm chamber 7 when its fuel is supplied.

(Function) When the priming pump is operated when starting the engine, the fuel in the fuel tank can be pumped to the carburetor, but since the carburetor needle valve at the entrance of the sensing chamber is closed, the fuel is pumped into the fuel reservoir chamber. be done. Since an air layer is completely formed above the fuel reservoir, the fuel compresses the air layer and flows into the fuel reservoir. Eventually, when the fuel pressure in the fuel reservoir reaches a certain level or higher, the check valve opens and returns the fuel to the fuel tank. Therefore, a constant amount of fuel remains in the fuel storage chamber.

Shihe-21 with 0 has been placed. The lever 21
One side is connected to the fuel valve 19 around the support shaft 20, and the other side is connected to the diaphragm 18. Therefore, when a strong negative intake pressure acts on the sensing chamber 7 through the main nozzle 5, the diaphragm 18 moves the lever 21 to prevent fuel from the fuel pump 8 from entering the sensing chamber 7 through the passage 16. The fuel valve 19 is held in the open position of the fuel supply passage 16 via the . Further, when the strong negative pressure in the sensing chamber 7 disappears due to the introduction of fuel into the sensing chamber 7, the fuel valve 19 is operated by the biasing force of the compression spring 22 that engages the lever 21 to inject the fuel into the sensing chamber 7. The passageway 16 is biased to block the passageway 16 to prevent the introduction of.

A priming pump 2 is provided in the middle of the fuel supply passage 15 for supplying fuel into the sensing chamber 7 when starting the engine.
3 are provided. A fuel reservoir chamber 25 having an air layer 24 formed therein is connected to the fuel supply passage 15 between the priming pump 23 and the fuel pump 8. On the other hand, this fuel supply passage 15 and the fuel supply passage 15 or fuel tank 17 on the upstream side of the priming pump 23 communicate with each other through a return passage 26.
6, the opening pressure of the fuel valve 19 (approximately 0,4 k
g/cTn') slightly lower than the fuel pressure (0.2~0.3
A check valve 27 is provided which opens when the engine temperature reaches 1 kg. Therefore, when the engine is started, if the priming pump 23 is operated, the fuel in the fuel tank 17 is pumped through the fuel pump 8 to the fuel valve 19 in the sensing chamber 7, but when the engine is stopped, The fuel valve 19 of the sensing chamber 7 is connected to the fuel supply passage 1 so as to prevent the introduction of fuel into the sensing chamber 7 by the biasing force of the compression spring 22.
6 is shut off, the fuel flows into the fuel reservoir chamber 25. Air accumulates in the upper part of the fuel storage chamber 25 to form an air layer 24, and the fuel is compressed and fed into the chamber 25 under pressure. Eventually, when the fuel pressure in the chamber 25 becomes equal to or higher than the opening pressure of the check valve 27, the check valve 27 opens and the fuel is returned to the fuel tank 17, and the fuel accumulates in the chamber 25 at a constant pressure. .
