Abstract (en)
[origin: GB2516468A] A fluid pressure operated actuator assembly comprises a tubular body having a wall enclosing a main passage, an actuator located in and movable along the main passage, a first direction chamber formed between the wall of the tubular body and the actuator, and at least one second direction chamber formed between the tubular body and the actuator. The exterior surface of the tubular body is provided with a first port which communicates with a passage extending through the wall of the tubular body from the first port to the first direction chamber, a second port which communicates with a passage extending through the wall of the tubular body from the second port to the or one of the second direction chamber(s), and a third port which communicates with a passage extending through the wall of the tubular body from the third port to the or another one of the second chambers. The first, second and third ports are all parallel to one another and the first port lies between the second and third ports.
