ABSTRACT:
The invention relates to a metering device for gaseous propellant for internal combustion engines. The invention resides in the device comprising a slit means (40) through which the gas flows, and a means (45, 47, 49 or 45, 47, 68, respectively) for covering at least one slit (42, 53) in dependence upon another flowing medium (28), for example, the air quantity taken in by an internal combustion engine, said means comprising a foil (47) pressed against the slit edges and rigidly secured at its end adjacent one end of the slits (42, 53) to said slit means (40), with a member (49, 68, respectively) which counteracts the bearing pressure engaging the other portion of said foil located adjacent the other slit end, further comprising in the area of the slits (42, 53) a member (45) which acts in the same direction as the bearing pressure, causes the foil (47) to bear against the slit edges and is displaceable in dependence upon the flow of the other medium (28) along the slits (42, 53).
