Gas Compressor
Gas flow in the Valve-In-Piston cylinder is direct
Dresser-Rand Co.low in the Valve-In-Piston cylinder is direct. As the discharge valves move toward the outer end, the frame end suction valve opens, allowing incoming gas to flow into the void created by the movement of the discharge valve. At the other end, the discharge valve opens as the gas is compressed against the outer end suction valve.

The compressor is a double-acting cylinder, so the process is reversed on the return stroke. It mounts four valves in the cylinder bore. Two suction valves are stationary and mounted at opposite ends. Two discharge valves are dynamic and mounted on the piston rod.
