摘要： A piston pump of the roller tappet type for high-pressure fuel delivery in fuel injection systems of internal combustion engines, particularly in common rail injection systems. A drive shaft that is supported in the pump housing and has a number of cam-like projections in the circumference direction. At least one tappet that is disposed in a cylinder chamber radially with regard to the drive shaft and in its radially inner end region has a rotatable roller which is supported so that it can roll in the circumference direction against the drive shaft in the region of its projections in order to reduce the wear in the region of the roller bearing. The pump is embodied so that a lubricant supply opening that leads from the circumference of the tappet and feeds into the radially inner tappet end region supporting the roller and at least during a part of the stroke, communicates with a lubricant supply line of the housing, which line feeds into the cylinder chamber.

摘要： The invention relates to a quantity control valve for a fuel injection system, used in internal combustion engines, which includes a longitudinal slide that is movable in a valve housing between a first and a second control chamber and that allocates the fuel, flowing in from at least one low-pressure pump, to at least one high-pressure pump. For driving the longitudinal slide, the inflowing fuel is delivered into the first control chamber via a throttle or baffle valve, past the longitudinal slide. In the second control chamber, there is either a restoring spring that urges the longitudinal slide in the direction of its closing position, or the longitudinal slide there has an effective face-end surface area upstream of which a control line containing a throttle valve ends; this end face is smaller in surface area than the effective surface area of the face end in the first control chamber. In the closing position, the longitudinal slide blocks off the outlet bore with one of its cylindrical guide portions, while with regard to the inlet bore it has a narrowed region, which opposite the longitudinal slide bore leaves a flow cross section open that changes gradually to zero in the direction of the guide portion. In the valve, the flow of fuel is controlled by a targeted manipulation of a cross section via a long slide stroke.

摘要： A fuel injection system for internal combustion engines is proposed, in which with the aid of a high-pressure pump fuel is pumped at high pressure into a high-pressure fuel reservoir (6), from which electrically controlled fuel injection valves (9) are supplied. The pressure in the high-pressure fuel reservoir is maintained in such a way that a first pump element (16) pumps fuel into the high-pressure reservoir with a variable pumping quantity, and a second pump element (17) as needed pumps a constant high-pressure fuel quantity into the high-pressure reservoir. A simple, economical system is thus obtained for furnishing high fuel pressure for injection by the fuel injection system (FIG. 2).

摘要： The invention relates to a quantity control valve for a fuel injection system, used in internal combustion engines, with a longitudinal slide that is movable in a valve housing between a restoring spring chamber and a control chamber and that allocates the fuel, flowing in from at least one low-pressure pump, to at least one high-pressure pump. For driving the longitudinal slide, the inflowing fuel in the control chamber is delivered past the longitudinal slide via a throttle or baffle valve. In the closing position, firstly, a cylindrical guide region of the longitudinal slide bounded on both sides by annular grooves blocks off an inlet bore. The guide region is wider than the diameter of the inlet bore. Secondly, it covers an outlet bore except for a partial intersection with the relieved annular groove shifted into the return in the opening direction of the longitudinal slide. By the disposition of the inlet and outlet bores in combination with the contour of the longitudinal slide, a zero quantity feed can be unambiguously represented in the blocking position of the longitudinal slide.

摘要： The invention relates to a radial piston pump for high-pressure fuel delivery in fuel injection systems of internal combustion engines, particularly in a common rail injection system. The pump includes a drive shaft that is supported in a pump housing and is embodied eccentrically or has a number of cam-like projections in the circumference direction. A number of pistons that are disposed radially with regard to the drive shaft are each disposed in a respective cylinder chamber and are set into a reciprocating motion in the radial direction in the cylinder chamber upon rotation of the drive shaft. Each respective cylinder chamber is sealed on the radial outside in relation to the drive shaft by a valve plate that has an intake side check valve and a high-pressure side check valve. In order to increase the efficiency of the pump, the intake side check valve has a tappet that passes through the valve plate and this tappet, on an end oriented toward the cylinder chamber has a valve disk that is placed in a sealed fashion against a sealing seat of the valve plate. On a side of the valve plate remote from the cylinder chamber, a device is provided, which pre-stresses the tappet in the closing direction.
