摘要： A carburetor for internal combustion engines with an acceleration pump whose pump chamber is connected to the float chamber by a suction duct having a suction valve. The pump chamber also is connected to the intake line section upstream of the throttle by a delivery duct having a pressure valve and a calibrated injection opening. The acceleration pump has a displacement member which is actuated via a linkage by a lever depending on the throttle position. The pump chamber has a flow duct, leading to the float chamber and having a cross section adjustable by means of a screw, and a second adjustable flow duct whose inlet has a valve actuated by the throttle position. The valve may have a spring which presses a closure member, held in a diaphragm, against the inlet overcoming the force of the fuel pressure. This spring also presses a plunger against a second lever arm which actuates the acceleration pump.

摘要： The fuel container has a float operating a fuel inlet valve (6) and a fuel outlet valve (7). A pump (12) pumps fuel from the fuel tank (10) to the inlet valve. The outlet valve returns fuel to the tank. The returned fuel flows through a heat exchanger (9) in the main tank. The fuel container may be located in the vehicle's carburettor. Circulating the fuel through the container in this way prevents it from overheating-- i.e. prevents its temp. rising above boiling point.

摘要： The carburettor has a float chamber (2) which contains a float (5). The flaot controls a needle valve (3) on the fuel inlet into the chamber. The float has a hollow space (7) inside it. The space has a connection (8) to the air space above the fuel in the chamber and a connection (9) to the liquid fuel in the chamber. The cross section of the connection to the fuel is smaller than the cross section of the connection to the air space. The flow through these connections dampens the oscillation of the float when the needle valve is calibrated and adjusted. In subsequent operation the float behaves normally.

摘要： The carburretor has a main mix outlet in the suction channel upstream of a throttle flap. This outlet is connected via a channel to a main mix system comprising a pipe, air correction nozzle and main fuel nozzle. A channel (11) leads into the pipe (3) downstream of the air correction nozzle (9). This channel is connected to the working chamber (12) of a pump (13) producing pulses of air. The pump is a membrane pump (13) whose membrane (14) is driven electromagnetically. The pump may have a control pressure chamber (21) connected via a nozzle (25) to atmospheric air. The working chamber may be connected via a nozzle (27) to atmospheric air. The main mix system provides uniform fuel flow even at the start of its conveying.
