  • PNEUMATIC INLET/BLOWDOWN VALVE ASSEMBLY
    Publication number: 20240061454
    Abstract: A fluid compressor system having a pneumatic inlet/blowdown valve assembly that utilizes pneumatic pressure and vacuum available in the fluid compressor system for the actuation of an inlet valve and a blowdown valve. The actuation of the inlet valve and the blowdown valve is synchronized via a piston-cylinder actuator having a first piston and a second piston axially connected. The pneumatic blowdown/inlet valve assembly uses a first stage vacuum pressure to actuate the first piston and the second piston from an idle state where the inlet valve is closed to stop a flow of working fluid into the fluid compressor system and the blowdown valve is open to depressurize the fluid compressor system to an actuated state where the inlet valve is open to allow the flow of working fluid into a first airend and the blowdown valve is closed to allow a pressure buildup in the fluid compressor system.
