Apparatus for injecting injection medium e.g. fuel into combustion engine, has closure element that is movably mounted with housing to open injection port if housing is elastically deformed by propagation of shock wave in injection medium

摘要

The apparatus has a housing (1) with a space (2) for accommodating injection medium (3), and an actuator (4) that is cooperated with pulse transmission element (6) for propagating the shock wave in injection medium. A closure element (7) is movably mounted with housing to open the injection port (8) if housing is elastically deformed by propagation of shock wave in injection medium.
