具有受热保护的弹性体密封元件的气体喷射器
摘要：
本发明涉及一种用于将气体燃料直接喷射到内燃机的燃烧室中的气体喷射器，包括：用于释放和关闭通道孔(3)的阀关闭元件(2)、第一密封座(4)和第二密封座(5)，其中，该第一密封座(4)是无弹性体的密封座，尤其是金属的或者陶瓷的密封座，该第二密封座(5)是具有至少一个弹性体密封元件(6)的密封座，该第一密封座(4)在该气体喷射器的轴向方向(X‑X)上比所述第二密封座(5)更靠近所述燃烧室(10)，并且，在所述第二密封座(5)上布置有第一绝热元件(7)。
摘要（英）：

The present invention relates to a gas injector for directly injecting a gaseous fuel into a combustion chamber of an internal combustion engine, comprising a valve closure member (2) for releasing and closing a passage hole (3), a first sealing seat (4), and a second sealing seat (5), wherein the first sealing seat (4)is an elastomer-free sealing seat, in particular a metallic or ceramic sealing seat; the second sealing seat (5) is a sealing seat with at least one elastomeric sealing element (6); and the first sealing seat (4) in the axial direction (XX) of the gas injector is closer to the combustion chamber (10) than the second sealing seat (5), and a first thermal insulation element (7) is arranged on the second sealing seat (5).
