Abstract
An injecting apparatus for injecting a fluid under pressure into an associated chamber, the injecting apparatus including: a body, a piston movable in the body under the action of fluid pressure in the associated chamber acting from externally against the piston, the piston being operable to compress fluid to be injected in a high pressure chamber, the piston being movable against the action of fluid pressure in a control chamber whereby movement of the piston is selectively controllable by controlling the fluid in the control chamber, an injector valve and an associated injector orifice in selective fluid communication with the high pressure chamber whereby high pressure fluid from the high pressure chamber can be injected through the injector orifice upon opening of the injection valve.

An injecting apparatus for injecting a fluid under pressure into an associated chamber, the injecting apparatus comprising:
- a body,
- a piston movable in the body under the action of fluid pressure in the associated chamber acting from externally against the piston, the piston being operable to compress in a high pressure chamber fluid to be injected into the associated chamber, the piston being movable against the action of fluid pressure in a control chamber whereby movement of the piston is selectively controllable by controlling the fluid in the control chamber,
- an injector valve and an associated injector orifice in selective fluid communication with the high pressure chamber whereby high pressure fluid from the high pressure chamber can be injected through the injector orifice upon opening of the injection valve,
- wherein the piston defines a first piston working area facing an associated chamber, the piston first working area being annular,
- wherein the first piston working area is defined by a first outer periphery having an outer sealing surface for movement relative to a first component of the injector and by a first inner periphery having a first inner sealing surface for movement relative to a second component of the injector, and
- wherein the second component is fixed relative to the body.
An injecting apparatus for injecting a fluid under pressure into an associated chamber, the injecting apparatus comprising:
- a body,
- a piston movable in the body under the action of fluid pressure in the associated chamber acting from externally against the piston, the piston being operable to compress in a high pressure chamber fluid to be injected into the associated chamber, the piston being movable against the action of fluid pressure in a control chamber whereby movement of the piston is selectively controllable by controlling the fluid in the control chamber,
- an injector valve and an associated injector orifice in selective fluid communication with the high pressure chamber whereby high pressure fluid from the high pressure chamber can be injected through the injector orifice upon opening of the injection valve,
- wherein the piston defines a first piston working area facing an associated chamber, the piston first working area being annular,
- wherein the piston defines a second piston working area being in fluid communication with the high pressure chamber,
- wherein the second piston working area is defined by a second outer periphery and a second inner periphery,
- wherein the first piston working area is defined by a first outer periphery having an outer sealing surface for movement relative to a first component of the injector and by a first inner periphery having a first inner sealing surface for movement relative to a second component of the injector, and wherein the first outer periphery has a diameter larger than the second outer periphery, and
- wherein the first inner periphery has a diameter equal to a diameter of the second inner periphery.
