A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages.A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam.

  • Un motor de vapor compuesto, es un tipo de motor de vapor donde el vapor es expandido en dos o más etapas.​​Una disposición habitual de un motor compuesto consiste en que el vapor se expande primero en un cilindro de alta-presión (AP); y después de perder calor y presión, entra directamente a uno o más cilindros de mayor volumen y baja-presión (BP). Los motores de expansión múltiple, emplean cilindros adicionales, preferentemente de presión más baja, para extraer energía del vapor. (es)
  • La motrice alternativa è una macchina esotermica nella quale l'energia termica si trasforma in lavoro meccanico; è un motore a combustione esterna e sfrutta il processo di combustione il quale avviene in un componente esterno normalmente il generatore di vapore, alimentata a sua volta da un bruciatore alimentato dal combustibile. Il sistema macchina si compone della caldaia, della motrice alternativa e da un condensatore. si possono classificare in base numero di espansioni del vapore in successione, si ha le motrici alternative: (it)
  • En kompoundångmaskin är en variant av en ångmaskin, i vilken ångan utvidgas i två eller flera faser. I strikt mening står begreppet kompound endast för tvåfas- eller dubbelexpansion, men begreppet används vanligen också för ångmaskiner med expansion i tre eller fyra faser. Försök började med kompoundmaskiner för lokomotiv på 1870-talet. Den schweiziska ingenjören Anatole Mallet var en pionjär, som satte in ett tvåcylinders kompoundmaskinlok på sträckan Biarritz-Bayonne 1876. (sv)
