本发明涉及一种用于双燃料发动机（17）的气体计量阀（1），其具有可移位的关闭体（6），其在与阀座（5）相对的位置处关闭气体计量阀 在从阀座（5）取下的位置，打开气体计量阀（1）。 气体计量阀（1）可在气体操作模式中致动，其中，气体计量阀（1）经由气体通道（13）将燃烧气体计量到双燃料发动机（17）的进气歧管（15）中， 并且在液体燃料操作模式中，气体计量阀（1）相对于在进气歧管（15）中普遍存在的压力保持密封地关闭。 阀座（5）沿着阀座导向件（4）可移动地定位，阀座（5）由于气体通道（13）中的燃烧气体压力，在气体操作模式中被压向远离闭合 主体（6）抵靠在气体计量阀（1）中的止动件（20）并保持在其操作位置，并且处于液体燃料操作模式的阀座（5）被来自进气歧管的压力 15）抵靠封闭体（6）。

The invention relates to a gas metering valve (1) for a dual fuel engine (17) having a movable locking member (6), of the accumulated in a valve seat (5) Position the gas metering valve (1) closes and in one of the valve seat (5) withdrawn position the gas metering valve (1) opens. The gas metering valve (1) is metered into an intake manifold (15) of the dual fuel engine (17) in a gas operation mode, in which the gas metering valve (1) fuel gas via a gas channel (13), and in a liquid fuel mode of operation in which the gas metering valve (1) against the in the intake manifold (15) prevailing pressure remains sealed closed, operable. The valve seat (5) is slidably disposed along a valve seat guide (4), wherein the valve seat (5) in the gas operation mode due to the internal gas pressure in the gas channel (13) is pressed by the locking member (6) off against a stop (20) in the gas metering valve (1) and is held in its operative position, and wherein the valve seat (5) in the liquid fuel mode of operation the pressure in the suction tube (15) sealingly against the locking body (6) is pressed.
