There is provided a seal assembly comprising: a first component and a second component spaced apart from the first component so as to define a passage for the transfer of fluid from an inlet of the seal assembly to an outlet of the seal assembly, wherein the first component comprises a concavity at least partially defining the passage, and wherein no part of the second component extends into the portion of the passage bounded by the concavity.

Seal assembly

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.

Injector apparatus

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 (), the first piston () further defining an injector orifice () through which the fluid can be injected into an associated chamber () from the high pressure chamber () and defining a valve seat (), a valve member () selectively operable to engage the valve seat () to operably isolate the high pressure chamber () from the injector orifice () and selectively operable to disengage the valve seat () to fluidly connect the high pressure chamber () with the injector orifice ().

An injector apparatus () for injecting fluid under pressure into an associated chamber () is provided. The injector apparatus () includes a 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 (), and a control piston () defining a control piston working area facing a control chamber (). The first piston () is moveable with a body of the injector apparatus () to compress fluid in the high pressure chamber () using the high pressure piston (), while movement of the first piston () is selectively controllable by controlling the fluid in the control chamber (). The first working area is larger than the control piston working area and the control piston () working area is larger than the high pressure working area.

A marine engine assembly is provided for propelling a marine vessel. The marine engine assembly includes an internal combustion engine configured to drive a propulsion arrangement, a turbocharger comprising a turbine portion having a turbine outlet, and a turbocharger exhaust conduit coupled to the turbine outlet. The turbocharger exhaust conduit acts as a primary support to the turbocharger within the marine engine assembly.
