  • the problem is the high load on a sealing device between the valve closing member and the valve seat, which also serves to increase the life of the valve due to the reduction in wear on the valve seat and the noise reduction in addition to increasing the tightness. Since, in contrast to liquid fuel injectors lubricated by the lubricating properties inherent in the liquid fuel, the wear characteristics of gas operated valves between the valve closure member and the valve seat is significantly less favorable, the design of the valve closure member valve seat portion and the sealing means therein is of particular importance to.
