| 发明名称 | Aircraft engine fuel pump bearing flow and associated system and method | ||
| 摘要 | An assembly or system is provided for selectively regulating journal bearing lubrication between at least first and second levels in an aircraft engine. A high pressure pump includes movable portions at least in part supported by a journal bearing. A selector valve is configured to selectively supply lubrication flow to the journal bearing. In addition, a relief valve is configured to receive a signal from the selector valve defining a pressure level at which the relief valve should relieve pressure. | ||

| 主权项 | 1. An assembly for selectively regulating journal bearing lubrication between at least first and second levels in an engine comprising: a pump for pressurizing aircraft engine fuel; a journal bearing for rotatably supporting at least a part of the pump; a selector valve configured to selectively supply lubrication flow to the journal bearing; and a relief valve configured to receive a signal from the selector valve defining a pressure level at which the relief valve should relieve pressure. | ||
