    摘要： A fuel system valve assembly may include a housing, a spring, and a body. The housing may have a fuel passage defined in part or more by a fuel passage wall. The fuel passage wall may have a seat and a cylindrical section. The cylindrical section may have a constant diameter and may be located downstream of the seat. In use, the body may reciprocate linearly in the housing between an open position and a closed position. The body may be biased to the closed position by the spring. The body may abut the seat when the body is in the closed position.

    摘要： A fluid control apparatus compact in size and high in performance, and a fuel supply system provided with the fluid control apparatus. The first valve opening direction in which a valve body of a relief valve is separated from a valve seat and the second valve opening direction in which a valve body of a discharge valve is separated from a valve seat are opposite to each other. The first valve opening drive pressure to have the valve body of the relief valve separated from the valve seat and the second valve opening drive pressure to have the valve body of the discharge valve separated from the valve seat are different from each other. The valve seat is provided integrally with the valve body. The fluid control apparatus is provided with a displacement limiting mechanism that limits the displacement of the valve body.

    摘要： An aircraft fuel system is provided and includes a metering valve having inlet and outlet sides to monitor fuel flow from the inlet to the outlet side, a check valve that, when opened, allows fuel to flow toward the inlet side during start and climb conditions and, when closed, prevents such fuel flow and an ejector pump, which is operably disposed between the check valve and the metering valve, and which, with the check valve closed, pumps fuel toward the inlet side during idle conditions.

    摘要： Disclosed is a fuel conveying device including a valve housing in which a pressure release valve and a non-return valve are arranged parallel to one another, the pressure release valve having a first inlet, which downstream of a valve seat opens into a valve chamber in which a valve body is movably arranged and which is in fluid connection with a second inlet for the non-return valve via a first outlet. The device improves the control response of the pressure release valve by providing the first outlet at the periphery of the valve chamber and in the axial direction with respect to a valve axis such that when the pressure release valve is open the flow from the valve chamber into the second inlet is a substantially radial flow.

    摘要： A valve for controlling fluid flow in a fluid system is disclosed. The valve includes a housing, a servo spool, and a piston. The servo spool defines a spiral groove and a spiral land. The piston defines an orifice configured to provide flow communication to a supply of pressurized fluid and an orifice configured to provide flow communication to a portion of the fluid system exterior to the valve. The valve further includes a main spool operably coupled to the piston. The main spool is configured to control flow of fluid in the fluid system. The spiral groove and spiral land are configured such that angular displacement of the servo spool results in a force imbalance on the piston, thereby moving the piston and the main spool in one of a first direction and a second direction.
