    • The combustion chamber device (1) comprises at least one combustion chamber (2), in particular a microcombustion chamber, including a substantially tubular body (3) which is closed at one end (3a) and in which a chamber (4) for supplying and igniting a combustible mixture is defined and communicates with a duct (8) having a length far greater than the mean transverse dimension thereof. The duct (8) can allow the generation and propagation of combustion, and of the resultant pressure wave, as well as the change-over from a slow deflagration condition to a rapid deflagration condition and/or from the deflagration condition to the detonation condition.
      The body (3) is surrounded by and enclosed in a rigid external sealed shell (9) which extends spaced apart from the wall (3c) of the body (3), forming, relative to the wall, a cavity or chamber (10) which is insulated from the external environment and in which a vacuum is produced. The internal surface (9a) of the shell (9) that faces the body (3) is able to reflect, towards the body (3), a major portion of the energy which is radiated from the body (3) during operation.
    • 燃烧室装置(1)包括至少一个燃烧室(2),特别是一个微燃室,包括一个在一端(3a)封闭的基本管状体(3),其中一个用于供应 并且点燃可燃混合物并且与具有远大于其平均横向尺寸的长度的管道(8)连通。 管道(8)可以允许燃烧的产生和传播以及所产生的压力波,以及从缓慢爆燃状态到快速爆燃状态和/或从爆燃状态到爆燃状态的转换。 主体(3)被包围并封闭在与主体(3)的壁(3c)间隔开的刚性外部密封外壳(9)中,相对于壁形成空腔或腔室(10) 其与外部环境绝缘并且其中产生真空。 面向主体(3)的外壳(9)的内表面(9a)能够在操作期间向主体(3)反射从主体(3)辐射的能量的主要部分。
