摘要： A carburetor with rotary valve includes an idle adjustment needle with an eccentric hole, accordingly a special adjustment tool used for idle adjustment needle has an eccentric boss; a carburetor with rotary valve includes an idle adjustment needle with an eccentric boss, accordingly a special adjustment tool used for idle adjustment needle has an eccentric hole. The idle adjustment needle must be cooperated with the special adjustment tool to carry out the adjustment, thus non-professional user can not casually adjust the fuel oil needle without the special tool, so that the engine can be maintained in the best setting condition to ensure the engine exhaust to meet the environmental protection requirement.

摘要： An apparatus for adjusting the air-fuel ratio of a fuel mixture to be supplied to an engine. The apparatus has a pair of needle valve bodies and a pair of receptacles formed in a main body of a carburetor for receiving the needle valve bodies. Each needle valve body has a needle and a head. The needles are axially movable relative to a respective needle orifice. The needles may be axially advanced and retracted by rotating the needle valve bodies within the receptacles to respectively decrease and increase the flow of the fuel mixture around the needles and through the orifices. To prevent tampering with the needle valve body setting, the head of the needle valve body has an unconventional shape requiring a specialized tool to rotatably adjust the needle valve body. To further prevent tampering, the head is recessed with the main body of the carburetor. A retainer is disposed in the main body of the carburetor and receives the needle valve bodies to facilitate maintaining alignment of the needle valve bodies relative to the receptacles. The retainer assures that a constant fuel calibration setting is maintained through the orifices by resisting displacement of the needles due to such factors as external forces applied to the head of the needle valve body or engine vibration.

摘要： In a first aspect, a carburetor fuel adjusting device that facilitates control of the quantity of fuel that flows from the fuel chamber to an air intake port of a carburetor by making it possible for the user to adjust an adjustment valve within the limits defined by emission control regulations. The carburetor fuel adjusting device has a cap having two appendages, and an engagement area to engage a valve extension of the fuel adjustment valves of a carburetor. The cap is retained by the retainer in either a disengaged position, or an engaged position wherein the engagement area of the cap becomes attached to the valve extensions. In the engaged position, the adjustment valves can be turned in unison with the cap within a range formed by the angle between the appendages which, when rotated, abut against stoppers. In a second aspect, a retaining plate of elastic material having two retainer holes adapted to receive and retain the pair of adjustment valves in a prescribed adjustment position is laid against an outer surface of the carburetor body. The adjustment valves each have a base-end portion and a small diameter portion, the threads of the base-end portion having an external diameter larger than that of the threads of the small diameter portion. The external diameter of the threads of the base-end portion is also larger than the diameter of each of the retainer holes of the retaining plate such that when the adjustment valve is screwed into the screw hole of the carburetor, the base-end portion cuts threads in the retainer holes of the retaining plate to thereby prevent rotation of the adjustment valve.

摘要： A temperature compensated carburetor having a fuel metering system including a variable restriction needle gate valve for varying the effective flow cross-sectional area of the main and/or idle fuel supply duct to modulate the flow rate of fuel to the carburetor venturi mixing passage. The needle gate valve is made of plastic material having a much greater coefficient of expansion than the aluminum carburetor body in which it is adjustably mounted such that differential linear expansion and contraction of the needle valve relative to the carburetor body in response to ambient temperature changes varies the flow-controlling cross-sectional area of the fuel duct inversely relative to ambient temperature changes. The needle valve is a rod-like body with a threaded cylindrical mounting portion at one end threadably secured in a threaded bore in the carburetor body. A reduced diameter extension of the needle body extends axially away from the mounting end of the needle body and has cylindrical stem portion slidable in another bore of the carburetor body. The needle body is unrestrained linearly from the free end of the stem portion to the needle body mounting portion. The free end of the stem is movable in a jet fuel feeding passageway of the fuel duct to thus vary the flow controlling cross-section thereof.
