Translate the following passage about the first compound steam engine built by the British engineer and inventor Arthur Woolf from Ukrainian into English.
У 1804 році англійський інженер Артур Вульф запатентував парову машину подвійного розширення (компаундну парову машину високого тиску Вульфа). У цій машині високотемпературна пара з парового котла надходила в циліндр високого тиску, а після цього відпрацьована у ньому пара з нижчою температурою і тиском надходила в циліндр (або циліндри) низького тиску. Це зменшувало перепад температури в кожному циліндрі, що в цілому знижувало температурні втрати і підвищувало загальний коефіцієнт корисної дії парової машини. Оскільки пара низького тиску мала більший об'єм, тому циліндри низького тиску мали більший діаметр (а іноді і більшу довжину) ніж циліндри високого тиску. Іноді один циліндр високого тиску був пов'язаний з двома такими ж паралельними циліндрами низького тиску. Таку схему було легше збалансувати.
Двоциліндрові компаундні машини можуть бути у наступних конструктивних виконаннях: перехресний компаунд (циліндри розташовані поруч, їх паропроводи перехрещені), тандемний компаунд (циліндри розташовуються послідовно і використовують один шток) і кутовий компаунд (циліндри розташовані під кутом один до одного, зазвичай 90 градусів, і працюють на один кривошип).
Після 1880-х років компаундні парові машини набули поширення на виробництві і транспорті і стали практично єдиним типом, що використовувався у пароплавах. Використання їх на паровозах не отримало такого поширення, оскільки вони виявилися занадто складними для умов використання у залізничному транспорті.
