Abstract
A gas compressor includes a compression chamber, an outlet valve, and a shuttle valve which disables the outlet valve when it is connected to an atmospheric pressure relief chamber in idle operation. A throttle line circumventing the shuttle valve is provided which permits by-passed flow between the compression chamber and the atmospheric pressure relief chamber in idle operation, thereby preventing deposits and moisture condensation in the downstream flow path to the pressure relief chamber due to the disabling of the outlet valve, which might otherwise lead to possible operational malfunctions. Compressed-air systems employed in the automotive industry represent an important area of application for the invention.
