Abstract: An injector apparatus (10) for injecting fluid under pressure into an associated chamber (32), the apparatus including a body (12), a first piston (14) moveable in the body, the first piston (14) defining a first working area facing an associated chamber (32), a high pressure piston (18, 118) defining a high pressure working area (182) facing a high pressure chamber (19, 119), the first working area being greater than the high pressure working area (182), the first piston (14) being operable to compress fluid in the high pressure chamber (19, 119), the first piston (14) further defining an injector orifice (76) through which the fluid can be injected into an associated chamber (32) from the high pressure chamber (19,119) and defining a valve seat (57), a valve member (92) selectively operable to engage the valve seat (57) to operably isolate the high pressure chamber (19, 119) from the injector orifice (76) and selectively operable to disengage the valve seat (57) to fluidly connect the high pressure chamber (19, 119) with the injector orifice (76).

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; and 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.
