Pneumatic inlet/blowdown valve assembly

A pneumatic inlet/blowdown valve assembly for a fluid compressor system comprising:

• an inlet valve regulating a flow of the working fluid into a first air-end, the first air-end operable to receive and compress a working fluid,
• a blowdown valve configured to release a pressure within the fluid compressor system, and
• a piston-cylinder actuator in communication with the inlet valve and the blowdown valve, the piston-cylinder actuator including:
• a first piston housed within a first cylinder,
• a second piston housed within a second cylinder, the first piston connected to the second piston, and
• the first piston and the second piston configured to be actuated between an idle state wherein the inlet valve is closed to stop the flow of the working fluid into the fluid compressor system and the blowdown valve is open to depressurize the fluid compressor system, and an actuated state wherein the inlet valve is open to allow the flow of the working fluid into the first air-end and the blowdown valve is closed to allow a pressure buildup in the fluid compressor system.

A fluid compressor system for compressing a working fluid comprising:

• a first air-end operable to receive and compress the working fluid;
• a second air-end operable to receive the working fluid from the first air-end and further compress the working fluid;
• and
• a pneumatic inlet/blowdown valve assembly including:
• an inlet valve configured to regulate a flow of the working fluid into the first air-end,
• a blowdown valve configured to release a pressure within the fluid compressor system, and
• a piston-cylinder actuator in communication with the inlet valve and the blowdown valve, the piston-cylinder actuator including:
• a first piston housed within a first cylinder, and
• a second piston housed within a second cylinder, the first piston connected to the second piston, and
• the first piston and the second piston configured to be actuated between an idle state wherein the inlet valve is closed to stop the flow of the working fluid into the fluid compressor system and the blowdown valve is open to depressurize the fluid compressor system, and an actuated state wherein the inlet valve is open to allow the flow of the working fluid into the first air-end and the blowdown valve is closed to allow a pressure buildup in the fluid compressor system.
