Abstract: The apparatus prevents fuel vapor from being discharged to an intake passage from a fuel metering chamber of a carburetor and maintains a substantially constant fuel pressure in the fuel metering chamber so as to stabilize the amount of the fuel discharged to the intake passage. The pump has a drive force produced by a pulsation pressure generated in a crank chamber of an engine or an intake tube. A discharge chamber of a fuel pump and a fuel tank are connected by a relief passage, and the relief passage is provided with a pressure regulating valve discharging a pressure equal to or greater than a set pressure in the discharge chamber to the fuel tank. Fuel vapor is prevented from being generated in an inner portion of a fuel metering chamber and the amount of fuel discharged to an intake passage is stabilized, by discharging a part of the fuel at a time when a pump discharge fuel pressure is high to the fuel tank together with the fuel vapor generated in the fuel pump, and only feeding the fuel at the set pressure to the fuel metering chamber. Further, because the fuel having a comparatively low temperature is circulated in the fuel pump and within the fuel tank by discharging excess fuel to the fuel tank, the carburetor is cooled, and the generation of fuel vapor is inhibited.

Abstract: The accelerator apparatus prevents air from remaining within a pump chamber and discharged fuel vapor from causing a pumping effect so as to a destabilize engine operation and increase of an exhaust gas content of harmful material, in an accelerator apparatus in which an accelerated fuel passage draws and discharges fuel to the pump chamber of an accelerator pump, which is connected to a main fuel passage. The pump chamber of the accelerator pump is mechanically coupled with a throttle valve and is connected to a fixed fuel chamber storing a fuel delivered to an intake passage at a fixed pressure by the accelerated fuel passage. Air remaining within the pump chamber and a fuel vapor generated within the pump chamber are discharged to the fixed fuel chamber, and fuel extruded from the pump chamber due to a pumping effect of the remaining air and the fuel vapor enters into the fixed fuel chamber, thereby preventing the alteration of a rate of the fuel flowing through a main fuel passage. Fuel in the pump chamber is fed to the fixed fuel chamber during acceleration so as to increase a pressure in the fixed fuel chamber, and an accelerated fuel is obtained by increasing the amount of the delivered fuel to the intake passage.

Abstract: An adjustment safeguard for a set screw that is rotatably held in a housing has a cap that is non-rotatably secured on the head of the set screw. The cap is received in a sleeve of the housing and surrounded with minimal radial play by the sleeve that is essentially coaxially positioned relative to the cap. The cap is received with its axial length in the sleeve. The cap has a projection and the sleeve has a stop arranged in the interior of the sleeve. Projection and stop interact with each other in a rotational direction of the set screw. The cap has a top part and a separate bottom part. The bottom part is secured axially and non-rotatably on the head of the set screw. The bottom part engages with form fit the top part in the rotational direction and is axially connected to the top part.
