Publication number: 20230053617Abstract: A metering valve has a main inlet port and a spool movable, and a housing outlet port in a housing. The spool has a metering inlet orifice selectively aligned with the main inlet port, and a metering outlet orifice selectively aligned with the main outlet port.

Patent number: 11421600Abstract: A metering valve spool controls a volume of fuel passing through a metering valve. The spool has a forward face. A line from a pump has a connection into a chamber. The face of the metering valve spool may contact a seal to block flow into the chamber. The metering valve is connected to a pressure regulating valve. The pressure regulating valve is to be connected to a combustor. A control selectively moves the metering valve spool to control a volume of fuel delivered from the chamber to the pressure regulating valve. The control is also programmed to move the metering valve spool to a position where a forward face of the metering valve spool seals on the seal to block flow from the pump from reaching the pressure regulating valve, and also from reaching the tap. A gas turbine engine is also disclosed.Type: GrantFiled: March 26, 2021Date of Patent: August 23, 2022Assignee: Hamilton Sundstrand CorporationInventors: Charles E.
