Abstract
A simplified control valve system is provided wherein a single multi-functional orifice provides the required bleed from the control cylinder chamber as well as the required venting of the system for blow down. Preferably, the control line will be an oil scavenger line and the multi-functional orifice will be positioned in the inlet passage of the valve to the compressor and a suitable oil sump positioned adjacent to the multi-optional orifice to collect any oil blown there through during blow down. The valve of the present invention is also adjustable by rotating the valve stem to which the control piston is connected.
