The pintle injector is a type of propellant injector for a bipropellant rocket engine. Like any other injector, its purpose is to ensure appropriate flow rate and intermixing of the propellants as they are forcibly injected under high pressure into the combustion chamber, so that an efficient and controlled combustion process can happen.

  • ピントル式噴射装置(ピントルしきふんしゃそうち、英名:pintle injector)は、ロケットエンジンの推進剤噴射装置の一型式で、アポロ計画の月着陸船の降下推進システムにおいて初めて使用された。アポロ計画が終了した後、需要が減り、半ば忘れ去られようとしていたが、その優れた特性に着眼した技術者たちによって、ピントル式噴射装置は現在、スペースX社のマーリンエンジンで使用される。 (ja)
  • Штифтовая форсунка, также игольчатый инжектор (pintle injector) — тип устройства для подачи топлива в камеру сгорания ракетного двигателя. Впервые был использован в программе «Аполлон» в посадочном двигателе лунного модуля. В настоящее время широко известно использование данного типа форсунки в семействе двигателей Merlin компании SpaceX. (ru)
  • O injetor com pino é um tipo de injetor de propelentes para um motor de foguete de combustível líquido bipropelente. Como qualquer outro injetor, seu objetivo é garantir o fluxo e a mistura apropriada dos propelentes enquanto eles são forçados sob alta pressão na câmara de combustão, de forma que ocorra um processo de combustão eficiente e controlado.
