摘要： The invention relates to an injector for internal combustion engines, which comprises a control valve upstream of the main flow valve. The aim of the invention is to improve an injector of the aforementioned type in such a manner that the connection between inlet and outlet, which is controlled via the valve member of the control valve and which passes the control room, functions inter alia as a throttle which reduces control leakage. To achieve this, the stop of the control piston is limited vis-à-vis the front overlapping the control room.

摘要： On the housing side, a high-pressure injector (1) has a central receptacle chamber (16) which lies between the actuator and the control valve (17) and is penetrated centrally by a control rod (23) which is multiple times as long as it is thick, and which receptacle chamber (16) forms, at least over part of its length, a pressure accumulator (24), in which the control rod (23) is surrounded directly by the fuel.

摘要： The invention relates to a device for the metered injection of a reducing agent into the exhaust manifold (2) of an internal combustion engine. The aim of the invention is to allow injection with continuously high and uniform atomization quality irrespective of the flow rate. For this purpose, a pump (1), especially a piston pump (18) or a diaphragm pump (29) is used. Said pump delivers the reducing agent in a pulsed manner to a nozzle (5) leading to the exhaust manifold (2). Said nozzle (5) is provided with a valve element (33) which automatically opens and closes a flow passage at the rate of the delivery pulse of the pump (1) and which does not allow injection of the reducing agent in lower pressure ranges so that atomization takes place in high pressure ranges only.
