Abstract
An injector apparatus for injecting fluid under pressure into an associated chamber, the apparatus including a body, a first piston moveable in the body, the first piston defining a first working area facing an associated chamber, a high pressure piston defining a high pressure working area facing a high pressure chamber, the first working area being greater than the high pressure working area, the first piston being operable to compress fluid in the high pressure chamber using the high pressure piston, the first piston defining a first axis, the high pressure piston defining a second axis, wherein the second axis is offset from the first axis.
Claims14
An injector apparatus for injecting fluid under pressure into an associated chamber, the apparatus comprising:
- a body,
- a first piston moveable in the body, the first piston defining a first working area facing an associated chamber,
- a first high pressure piston defining a high pressure working area facing a first high pressure chamber,
- a second high pressure piston facing a second high pressure chamber and the high pressure working area is defined by the first high pressure piston facing the first high pressure chamber and the second high pressure piston facing the second high pressure chamber,
- the first working area being greater than the high pressure working area, the first piston being operable to compress fluid in the high pressure chamber using the high pressure piston,
- the first piston defining a first axis,
- the high pressure piston defining a second axis,
- wherein the second axis is offset from the first axis.
An injector apparatus for injecting fluid under pressure into an associated chamber, the apparatus comprising:
- a body,
- a first piston moveable in the body, the first piston defining a first working area facing an associated chamber,
- a plurality of high pressure pistons defining a high pressure working area facing a corresponding plurality of high pressure chambers,
- the first working area being greater than the high pressure working area, the first piston being operable to compress fluid in the high pressure chamber using the high pressure piston
- the injector apparatus 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 the first ratio is different from the second ratio,
- the high pressure working area of the first ratio is defined by a first selection of the plurality of high pressure pistons facing the corresponding high pressure chambers, and
- the high pressure working area of the second ratio is defined by a second selection of the plurality of high pressure pistons facing the corresponding high pressure chambers,
- wherein the first selection is different to the second selection.
