摘要： The invention relates to a pressure regulator for a fuel injection system of an internal combustion engine, in which a pressure difference prevailing between a pressure inlet and a pressure outlet can be kept essentially constant by opening and closing at least one valve, which valve includes a valve closing member forced into the closing position against a valve seat by the action of a valve closing spring. The valve spring is formed by means of at least one pivotably supported valve leaf spring, and an arm, toward the valve seat in terms of the pivotable bearing means, of the valve leaf spring is braced on the valve closing member, and an arm of the valve leaf spring located on the side opposite the valve seat is braced on a support body, in such a way that a torque equilibrium prevails at the valve leaf spring.

摘要： It has been determined that a fuel delivery system with a fuel supply line and electromagnetically actuatable fuel injection valves produce fuel oscillations during opening and closing of the fuel injection valves and therefore generates noise, which is transmitted into the passenger compartment of the vehicle and annoys the passengers. In order to damp this kind of noise, at least one elongated, hollow damping body is connected at right angles to the fuel supply line and has a closed end. The axial length of the hollow damping body corresponds to 11/2 times the wavelength of the fuel oscillation to be damped in the fuel supply line. The length of the at least one damping body can also correspond to 11/2 times the wavelength of the fuel oscillation to be damped in the fuel supply line, divided by 2 or by a multiple of 2. The fuel delivery system is particularly suited for mixture compressing internal combustion engines with externally supplied ignition.

摘要： The invention relates to a pressure regulator for a fuel delivery system of an internal combustion engine for regulating a fuel pressure, including a valve, which has a valve ball that is pressed against a valve seat in the closed position by the action of a valve leaf spring. A segment of a hemisphere of the valve ball oriented toward the valve leaf spring protrudes into a recess associated with the valve leaf spring. This improves the noise behavior and regulating behavior of the pressure regulator.

摘要： Fuel pumping apparatus having an impoundment container, disposed in a tank, in which impoundment container a pumping assembly is disposed that pumps fuel to the internal combustion engine. A jet pump is supplied with some of the fuel pumped by the pumping assembly and pumps fuel out of the tank into the impoundment container. Below the pumping assembly, near a bottom of the impoundment container, there is a suction chamber, from which the pumping assembly aspirates fuel. A connection of the suction chamber to the impoundment container is controlled by a float valve, disposed laterally next to the pumping assembly, and by means of this valve, when the impoundment container is full, the suction chamber communicates with the impoundment container; in this state, the pumping assembly aspirates fuel from the impoundment container. A connection of the suction chamber to the tank is controlled by a check valve, which is disposed on the bottom of the impoundment container and by which the suction chamber communicates with the tank when the impoundment container is empty; in this state, the pumping assembly aspirates fuel from the tank.
