    摘要： Ein Vergaser zur Zufuhr von Kraftstoff/Luft-Gemisch zu einem Verbrennungsmotor (1) besitzt eine Kraftstoffpumpe (15), eine von einem Bediener zu betätigende Förderpumpe (28) sowie eine Anreicherungseinrichtung (29). Der Vergaser (9) weist mindestens eine Kraftstoffkammer (23) auf, in die die Kraftstoffpumpe (15) Kraftstoff fördert. Aus der mindestens einen Kraftstoffkammer (23) wird im Betrieb Kraftstoff in einen in dem Vergaser (9) ausgebildeten Ansaugkanalabschnitt (10) zugeführt. Die Förderpumpe (28) ist zur Förderung von Kraftstoff aus der Kraftstoffkammer (23) ausgebildet. Die Anreicherungseinrichtung (29) weist eine Anreicherungskammer (30) auf und ist zur Zufuhr von Kraftstoff aus der Anreicherungskammer (30) zu dem Verbrennungsmotor (1) ausgebildet. Es ist vorgesehen, dass die Anreicherungskammer (30) ein veränderliches Volumen aufweist und dass die Förderpumpe (28) und die Anreicherungseinrichtung (29) derart gekoppelt sind, dass eine Betätigung der Förderpumpe (28) zu einer Veränderung des Volumens der Anreicherungskammer (30) führt. Für einen Verbrennungsmotor mit einem Vergaser (9) ist vorgesehen, dass die Anreicherungskammer (30) mit einem Kurbelgehauseinnenraum (8) des Verbrennungsmotors (1) strömungsverbunden ist.

    摘要： A device for controlling a choke valve of a carburetor for an engine includes: a choke closed state hold device for holding, in a closing position, a choke lever urged by a spring in a direction for opening the choke valve, when the choke lever is turned to the closing position, the choke closed state hold device releasing the choke lever from the held state by a throttle operation thereafter performed; a control lever which turns between a low-temperature position and a high-temperature position, and which at its low-temperature position limits the position of the choke lever released from the choke closed state hold device to an intermediate position and at its high-temperature position limits the position of the choke lever to an opening position; a first control spring which urges the control lever toward the low-temperature position; and a second control spring which is made of a shape memory alloy, and which turns the control lever to the high-temperature position when the engine temperature reaches a predetermined high temperature. With this arrangement, the opening of the choke valve is controlled in a rational way according to changes in engine temperature, to thereby stabilize warm-up operation and improve the fuel consumption rate.

    摘要： An automatic choke apparatus for engine has a reduced height by juxaposing a thermally operative element and a heat generating element for heating a thermally expanding body (7d) of the thermally operative element (7) through a heat conducting plate (14a). The thermally operative element and the heat generating element (5) are laterally arranged in a housing. The heat conducting plate (14a) is additionally provided for conducting heat generated by the heat generating element (5) to a thermally expanding body (7d) formed in a portion of the thermally operative element (7).

    摘要： An air inlet control system for a carburetor of an internal combustion engine. The system includes a magnet, an air inlet valve, and a temperature controlled limiter. The magnet is used to automatically attract the air inlet valve towards a fully closed position. The temperature controlled limiter limits the range of movement of the air inlet valve based upon the temperature of the engine. The limiter limits the open position of the valve to a position less than fully open when the engine is cold and, limits the closed position of the valve to a position less than fully closed when the engine is hot.
