Abstract: A valve arrangement for the measured supply of gaseous fuel in internal combustion engines with a plurality of electromagnetically operable control valves of an individual cross-section, with the control valves being embodied as seat valves, allowing the allocation of the valve arrangement to an internal combustion engine, and the valve arrangement comprising a nominal cross-section for providing a predetermined volume flow, with the seat valves being designed such that a sum of the individual cross-sections is at least equivalent to the nominal cross-section, an effective cross-section due to a valve stroke of all seat valves is equivalent to the nominal cross-section, and the effective cross-section is smaller or equivalent to the sum of individual cross-sections.

Abstract: The invention relates to an electromagnetically operable high-pressure gas valve, which is embodied as a pilot valve with a pilot seat and a pilot opening and a main seat with a main opening, with the pilot opening connecting a high-pressure side with a low-pressure side of the valve and it being possible to close it via a main sealing element, the main opening connecting the high-pressure side to the low-pressure side of the valve and it being possible to close it by a main sealing element, and the valve comprising a pilot anchor which acts upon the pilot sealing element, and comprising a main anchor, which acts upon the main sealing element, with the valve comprising a coil that is suitably embodied and arranged to act upon the pilot anchor and the main anchor such that a pilot stroke and a main stroke are independent from each other.
