Where are the suction and discharge valves located in a reciprocating compressor?

In a reciprocating compressor, the design typically incorporates suction and discharge valves in both locations—under and over the plate. This setup allows for efficient intake and displacement of the working fluid during the compression cycle.

The suction valves, usually situated on the top or upper part of the plate, enable the gases to be drawn into the cylinder during the intake stroke. Subsequently, when the piston moves down, it compresses the gas, which increases pressure. After reaching a certain pressure threshold, the discharge valves, located beneath the plate, open to allow the compressed gas to exit the cylinder and continue through the system.

This dual positioning of the valves enhances the compressor’s overall efficiency. It streamlines the flow of gases through the system and minimizes losses that might occur if the valves were positioned incorrectly or solely in one area. Therefore, the response that indicates the presence of suction and discharge valves in both positions appropriately reflects the functional design of a reciprocating compressor.
