Abstract
A compressor installation having a reduced load at start-up, including a gas compressor having an inlet and an outlet and a start-up valve connected to the outlet of the compressor. The start-up valve includes a valve body having an inlet and an outlet, a valve plunger connected to the inlet of the valve body, a spring connected to the valve body and the valve plunger, and a muffler. The start-up valve is configured to discharge the compressed gas through the muffler to atmosphere to reduce the load on the motor at start-up. After starting the compressor, the spring in the start-up valve is compressed after pressure is increased by the compressor and the discharge through the start-up valve to atmosphere is closed.
