Refill stroke (последовательность верная)
1 When a mechanical force pulls the piston upwards, 2 the reduced pressure causes the inlet valve (A) to open. 3 Water enters the cylinder and fills the space beneath the piston. 4 The outlet valve (B) remains closed because of the pressure of water in the outlet pipe because 5 the pressure in the cylinder beneath the piston begins to fall.
Цикл заполнения (последовательность верная)
1 Когда механическая сила тянет поршень вверх, 2 пониженное давление заставляет впускной клапан (а) открыться. 3 Вода поступает в цилиндр и заполняет пространство под поршнем. 4 Выпускной клапан (в) остается закрытым из-за давления воды в выпускной трубе, поскольку давление в цилиндре под поршнем начинает падать.
Compression stroke (последовательность изменена)
2 When a mechanical force pushes the piston downwards, 8 the pressure beneath the piston begins to rise. 4 This causes the inlet valve to close. 6 The cylinder now traps the water because it cannot escape back through A. 7 and when the pressure is sufficiently high the outlet valve opens and under 5 the high pressure water is forced up the outlet tube. 1 Water continues to flow up the tube until the piston reaches its lowest point 3 and then the cycle starts again.
Цикл сжатия (последовательность изменена)
2 Когда механическая сила толкает поршень вниз, давление под поршнем начинает расти. 4 Это приводит к закрытию впускного клапана. 6 Теперь цилиндр сдавливает воду, потому что она не может выйти обратно через A, 7 и, когда давление достаточно высокое, выпускной клапан открывается, и под высоким давлением 5 вода выталкивается в выпускную трубку. 1 Вода продолжает продвигаться вверх по трубке до тех пор, пока поршень не достигнет своей нижней точки 3, а затем цикл начинается снова.
