The trailing and leading edges of the choke and throttle valves, respectively, preferably overlap during wide open throttle operation to separate a single intake passage bore into an air intake passage above the choke and throttle valves and an air/fuel intake passage below the choke and throttle valves. The choke valve is preferably bent to minimize operational rotation and limit fuel spit back.

Abstract: A scavenging carburetor having an improved relationship between scavenging air flow and fuel-and-air flow to an engine over its range of operating conditions. The carburetor has a butterfly throttle valve and a plug-type scavenging valve. Levers are attached to support shafts of the valves and are connected to each other by a connecting rod so as to synchronize movement of the valves. Because of the different opening angle versus open area properties of the two valves, the supply of the scavenging air is minimized over a low speed range of the engine so as to achieve a stable low speed operation and a stable acceleration from idle conditions and a relatively large amount of scavenging air is supplied over a high speed range of the engine for the given amount of fuel-and-air mixture that is supplied. Therefore, the fuel-and-air mixture supply and scavenging air supply is better matched to the requirements of a particular engine than was possible with conventional combinations of valves.

Abstract: A carburetor arrangement for a two-stroke engine (1) is for a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like and has an intake channel (22). The intake channel (22) is partitioned by a partition wall (11) into an air channel (8) and a mixture channel (21). A fuel opening (27, 28) for supplying fuel to the two-stroke engine (1) opens into the mixture channel (21). The carburetor arrangement has a carburetor (17) having a carburetor housing (18) wherein an intake channel section (32) is formed. A throttle flap (24) is pivotally journalled in the carburetor housing (18). A good partitioning of the air channel (8) from the mixture channel (21) results with a simple manufacture of the carburetor (17) when a partition wall section (31, 48, 58, 68, 78, 88, 98) is configured as a separate component upstream of the throttle flap (24) and is held in the intake channel (22).

Abstract: A charge forming apparatus for delivering a controlled mixture of fuel-and-air to an engine has a butterfly-type throttle-choke valve disposed in a fuel-and-air mixing passage. Incoming air flowing through a downstream primary venturi of the mixing passage creates a strong negative pressure which induces fuel flow through a feed passage into the venturi from a fuel metering chamber held at near atmospheric pressure. When the engine is decelerating, substantial closure of the choke valve creates a secondary venturi having a vacuum which dynamically counters the effect of the primary venturi vacuum reducing fuel flow through the feed passage and causing the engine to run leaner and preventing egine stalls and reducing emmissions.

Abstract: An X-ray analysis system controls the humidity of a sample. The analysis system has a device for dividing a gas flow stream into two portions and for submerging a membrane humidifier tube, containing one of the gas flows, in a water bath in which the gas passing through that tube is moisturized to a desired degree. The two gas flows are subsequently reunited at a controlled temperature to provide for combined moisturized gas at a desired temperature and humidity. The gas is then sprayed onto the sample and an excess moisturized gas vented from the chamber to maintain a moisturize gas sample without condensation of water on or near the sample. This system and a method for its use allow measurements of samples to be made as a function of humidity and temperature over wide ranges of these parameters under highly stable conditions in a straightforward manner which are not susceptible to malfunction and which can be produced and operated at low cost.

Abstract: Flange assembly for supporting a structure that provides scavenging air supply to an internal combustion engine at the carburetor to the engine. The assembly includes a thin-body flange that is configured to be abuttingly installed upon an end surface of the carburetor. The carburetor has its combustion air intake or port exposed at an outer surface for intaking air for the combustion process.

A combustion air aperture is provided that extends through the thin-body flange. The combustion air aperture is located in the flange for alignment with the combustion air intake. By this alignment, fluid communication is established across the flange and into the carburetor when the flange is abuttingly installed upon the carburetor.

Abstract: A carburetor preferably of a diaphragm type for an internal combustion engine has a low speed circuit for starting and idling of a cold engine. An air bleed line of the low speed circuit communicates between an inlet of a fuel and air mixing passage of the carburetor and an emulsifying chamber of the low speed circuit. Fuel flows to the emulsifying chamber from a fuel metering chamber and is regulated by a low speed idling adjustment needle screw. The bleed air and the fuel mixes within the emulsifying chamber and flows into the mixing passage between the throttle valve and the outlet of the mixing passage. Promoting this flow is a high vacuum produced by cranking and idling of the engine and accentuated by the substantially closed throttle valve. The fuel-and-air mixture is rich during cold idling as a result of the closed air bleed line. When the engine warms up, the air bleed line is opened via the restrictor valve.

Abstract: A diaphragm carburetor for a combustion engine having a manual starter has a housing and a control chamber arranged in the housing and filled with fuel. A suction channel is arranged in the housing and has a venturi section.

Abstract: The object of the present invention is to easily provide an appropriate amount of starting fuel for all-purpose engines, without requiring any special skill. The upstream side and downstream side of a throttle valve in an air intake passage are connected by a bypass. This bypass and a constant-fuel chamber are connected by an increased-fuel passage which is equipped with a check valve. The system is arranged so that the bypass and increased-fuel passage are opened and closed more or less simultaneously by an opening-and-closing valve. The necessary amount of starting fuel can be supplied to the engine in a short time by means of the increased-fuel passage, so that starting can be accomplished by cranking the engine a few times. The flow of air into the constant-fuel chamber from the bypass is prevented by the check valve so that rough idling and the need to expel inflowing air are eliminated; and starting operations may be performed in any desired order.
