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.
Claims14
A valve arrangement for the measured feeding of a gaseous fuel into internal combustion engines comprising a plurality of electromagnetically operable control valves showing an individual cross-section, with the control valves being embodied as seat valves, it is possible to allocate the valve arrangement to a combustion chamber, and the valve arrangement comprising a nominal cross-section for providing a predetermined volume flow, wherein the seat valves are embodied such that
- a sum of the individual cross-sections, is higher than the nominal cross-section,
- an effective cross-section based on a valve stroke of all seat valves is equivalent to the nominal cross-section, and
- the effective cross-section is lower than the sum of the individual cross-sections.
A modular system for the design of valve arrangements to form nominal cross-sections from 50 mm2 to 1500 mm2 with a plurality of electromagnetically operable control valves, embodied as identical seat valves and arranged in a common housing, each showing an individual cross-section, wherein
- the individual cross-section is smaller than the nominal cross-section,
- a number of control valves used is greater than the nominal cross-section minimally required for the volume flow divided by the individual cross-section,
- a valve stroke is adjusted to the number of control valves such that an effective cross-section at a valve stroke is equivalent to the nominal cross-section, and
- the number of control valves used is selected such that a total stroke work of all control valves is at least halved in reference to an individual valve.
