Abstract

See full text

An apparatus is provided and may include a control valve that moves a pressure-responsive unloader valve between a first position permitting flow through a valve plate and into a compression mechanism and a second position restricting flow through the valve plate and into the compression mechanism. The control valve may include at least one pressure-responsive valve member movable between a first state supplying discharge-pressure gas to the unloader valve to urge the unloader valve into one of the first position and the second position and a second state venting the discharge-pressure gas from the unloader valve to move the unloader valve into the other of the first position and the second position.
