A bleed system including control circuitry and a variable jet pump. The control circuitry is configured to receive a signal indicative of a fluid parameter in the bleed system and cause the jet pump to alter a mixing ratio of a higher pressure gas and a lower pressure gas based on the signal. The jet pump is configured to combine the lower pressure gas and the higher pressure gas in the mixing ratio to generate a mixed gas. The jet pump is configured to supply the mixed gas to one or more gas loads in the bleed system. In examples, the control circuitry is configured to establish a system setpoint for the fluid parameter based on an operating status of the one or more gas loads.

Variable jet pump

Seals, ball valve assemblies, and methods of operating ball valves assemblies are provided. The seal includes an annular jacket, a restrictor, and a spring energizer. The annular jacket includes a first annular pocket and a second annular pocket. The restrictor is disposed in the first annular pocket and is capable of restricting shrinkage of the first annular pocket to a predetermined diameter range, if the seal is exposed to a temperature within a predetermined temperature range. The spring energizer is disposed in the second annular pocket and is configured to supply a force against the annular jacket to maintain the seal against a contact surface.

An apparatus is provided for a valve actuator assembly comprising an actuator housing, a piston, and a spring. The piston is disposed within the actuator housing. The piston is configured to couple to a valve element, and includes an inner cylindrical section and an outer cylindrical section. The outer cylindrical section of the piston is spaced apart from the inner cylindrical section to define a recess. The piston is further configured to move within the actuator housing in a first direction and a second direction, to thereby move the valve element toward a first position and a second position, respectively. The spring is disposed within the actuator housing, and is configured to supply a bias force that urges the piston to move in the first direction. The spring is at least partially disposed within the recess, and at least partially surrounding the inner cylindrical section.
