An injector apparatus (110) for injecting fluid under pressure into an associated chamber (132), the apparatus including a body (112), a first piston (114) moveable in the body, the first piston defining a first working area facing an associated chamber (132), a high pressure piston (18,118) defining a high pressure working area facing a high pressure chamber (19), the first working area being greater than the high pressure working area, the first piston (114) being operable to compress fluid in the high pressure chamber using the high pressure piston (118), the injector apparatus (110) having a first configuration having a first ratio of the first working area to high pressure working area and having a second configuration having a second ratio of the first working area to the high pressure working area, wherein a first ratio is different from the second ratio.
An injector apparatus for injecting fluid under pressure into an associated chamber, the apparatus including
The injector apparatus as defined in claim 10, wherein the high pressure working area of the third ratio is defined by a third selection of the plurality of high pressure pistons facing the corresponding high pressure chambers, the third selection being different to the first selection and second selection.
