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.

摘要： The invention relates to a valve arrangement (2) for metering a fluid medium into an exhaust line (22), comprising a valve seat (10) which acts together with a closing body (12) and in which a valve passage (14) is implemented, and a perforated disc (6) that is disposed downstream of the valve seat, closes off the valve passage, and has at least one axial hole (8) in the area of the valve passage through which the fluid medium can be injected into the exhaust line (22). The valve arrangement further comprises a connecting flange (16) for connecting the valve arrangement (2) to the exhaust line (22) in a fluid-tight manner, wherein the perforated disc (6) extends from the valve passage to the connecting flange and is implemented such that said perforated disc seals the connecting flange against the exhaust line in a fluid-tight manner in the installed state. A separate seal is thus no longer required, because the perforated disc performs the sealing function.

摘要： The invention relates to a device (40) for reducing pollutants, in particular nitrogen oxides, in an exhaust gas flow of an internal combustion engine, comprising a reducing agent (46), in particular a urea-water solution, which is stored in a storage tank (42), a metering module, in particular a nozzle (68), for injecting the reducing agent (46) into the exhaust gas flow, and a pump (56, 100) for delivering the reducing agent (46) from a suction point (62) in the storage tank (42) to the metering module via lines (58, 66). According to the invention, the pump (56, 100) lies beneath a reducing agent level (44) in the storage tank (42), and a non-return valve is provided. As a result of the non-return valve, the device (40) is prevented from refilling with the reducing agent (46) after the reducing agent (46) is completely sucked back from the device (40) after shutting off the internal combustion engine, in particular after extended idle times of the internal combustion engine. In a first embodiment, the non-return valve is a filter (64) that is formed with a plurality of screens (80, 82, 84, 86) which are connected one behind the other, which have a special microstructure, and which are formed with a plastic material. In the case of a second embodiment, the non-return valve is formed with a hermetically sealing valve (158) which is heavily preloaded by a spring force in particular and which is directly integrated into the pump (100) that is necessary for delivering the reducing agent (46) in the device (40).

摘要： A metering device for introducing liquid reducing agent into an exhaust gas pipe. A metering valve is supplied with contents from a working tank by a delivery unit and dispenses the tank contents in a discharge direction. The delivery unit establishes a negative pressure between the delivery unit and the metering valve when the delivery direction is reversed. The negative pressure causes gas to be drawn off through the metering valve against the discharge direction. The delivery direction is reversed by either a feed pump with a reversible effective direction or a feed pump and a repolarization valve which communicates with the feed pump and transposes an inlet and an outlet of the feed pump.
