Document Type and Number:
Japanese Patent JP2004515440
Kind Code:
A
Abstract:
The invention relates to an injection device for the metered injection of two liquids, in predeterminable quantity ratios, into a reaction chamber, the device having a housing (1) that includes an injection nozzle, the opening (13) of which forms an injection valve with the valve seat (14) in the housing (1) and a valve body (15) that can be positioned on the valve seat (14); the valve body (15) can be moved by a first actuator; the collection chamber (16) of the device is associated with the nozzle opening (13), and is connected to a supply line (17) for the first liquid (A) and a supply line (21) for the second liquid (B), with a metering valve (22) being set up to block at least one supply line (21) to the collection chamber, the valve being actuated by a second actuator; one of the two liquids is under a higher pressure than the other liquid; the device further has a control device (10), which can actuate the two actuators as a function of a load-stipulated total injection quantity and as a function of a predeterminable quantity ratio of the two liquids (A, B), with at least one valve being actuated in a clocked manner.
