    Abstract: A lubricated high pressure fuel pump assembly is provided, comprising a fuel pump, a sealed enclosure and a pump lubrication circuit. The fuel pump includes a pump drive shaft via which the fuel pump is configured to be mechanically driven. The sealed enclosure is configured to surround a first portion of the pump drive shaft, wherein the first portion is exterior to the fuel pump. The pump lubrication circuit comprises a lubricant reservoir and a lubricant pump configured to pump lubricant from the lubricant reservoir to the pump drive shaft. The sealed enclosure is configured to prevent fluid leakage from the fuel pump via the first portion of the pump drive shaft and the lubricant reservoir is configured to collect the lubricant from the pump drive shaft, such that the lubricant is retained within the lubricated high pressure fuel pump assembly.

    Abstract: A fuel flow control system includes a centrifugal pump, a gas inlet valve, and a control. The centrifugal pump has a fuel inlet, a gas inlet, and an outlet. The gas inlet valve is disposed upstream of the gas inlet and is responsive to valve position commands to move between a closed position, in which inert gas is prevented from flowing into the gas inlet, and a plurality of open positions, in which inert gas may flow into the gas inlet. The control is coupled to the gas inlet valve and is configured to supply the valve position commands to the gas inlet valve to command the gas inlet valve to selectively move to the closed position, such that the centrifugal pump is configured to operate as a fuel pump, or any open position, such that the centrifugal pump is configured to operate as a fuel-gas mixer.

    Abstract: A valve arrangement for a high pressure pump includes a pump housing with a depression, and a valve housing configured to be inserted in the depression, and a clamping disc. The valve housing has at least one radial projection with a first axial boundary surface and a second axial boundary surface arranged opposite the first axial boundary surface, wherein the clamping disc extends radially over the radial projection of the valve housing and has a third axial boundary surface that corresponds with the second axial boundary surface of the valve housing. On the circumferential side, the clamping disc has a thread that can be screwed into a thread on the inner side of the depression to brace the valve housing onto the first boundary surface.
