摘要： An interlocking lever having first and second cam faces is mounted on a throttle valve stem, and a throttle valve is arbitrarily opened to perform start-up in a state in which the first cam face makes contact with the choke valve lever and the interlocking lever is stopped during low-temperature start-up with the choke valve closed. After the choke valve has been returned to the fully open position, the throttle valve alone is opened with a small degree of opening to perform low-load operation; and in the mid- and high-load region, the interlocking lever integrally turns with the throttle valve, the second cam face pushes the air valve lever, and the throttle valve and air valve are caused to open and close proportionally. Preferably, the degree of opening of the throttle valve for low load operation is adjustable.

摘要： The invention concerns a pump for pumping a first liquid, called transferred liquid, and comprising a main unit (18) for pumping the transferred liquid actuated by an auxiliary unit (20) pumping a second liquid, called working liquid. The main (18) and auxiliary (20) units are housed in a casing (16) generally cylindrical in shape. The main unit (18) comprises at least two valves (36, 38), for respectively sucking up and delivering the transferred liquid, borne by a valve body (40) housed in the casing (16). Each valve (36, 38) communicates with two chambers, respectively a suction chamber (46) and a delivery chamber (48) for the transferred liquid, defined by opposite surfaces (50, 52) provided in the valve body (40) and the casing (16). Said surfaces (50, 52) comprise two matching shoulders (50E, 52E) pressed against each other so as to form a tight joint plane separating the suction chamber (46) and the delivery chamber (48). The invention is applicable to a high pressure pump for supplying a motor vehicle engine with fuel.

摘要： An injection pump comprises several modules in a housing. Each module has a chamber supplying an injection circuit, separated by a deformable diaphragm from a compartment defined by a bore of the housing and by a reciprocating piston. The chamber is connected to a fuel supply and is connected to the injection circuit by a non-return valve. The pressures of the liquid in each compartment are adjusted independently. All pistons are driven by a same cam.

摘要： The invention is directed to a fuel-injection arrangement for a two-stroke engine in a motor-driven chain saw. An injection pump is mounted in a base housing with the injection pump including a pump piston axially displaceable in a pump cylinder. The pump piston delimits a pump chamber. The pump chamber is connected via a suction valve to a fuel tank. The fuel drawn by suction is pumped by the pump piston via a pressure valve, an injection line and an injection valve to the engine. For driving the pump piston, the latter is connected at one end to a membrane via a membrane plate. The membrane delimits a work chamber charged with fluctuating crankcase pressure. A simple assembly is provided by arranging the pump chamber, the suction valve and the pressure valve in a common valve housing which, in turn, is seated in the base housing of the injection pump in a seal-tight manner. The injection line is connected directly to the valve housing. This permits a preassembly of the valve housing with the valves provided therein which facilitates the manufacture of the fuel-injection arrangement.
