ABSTRACT:
An adjustable valve assembly as disclosed wherein a plurality of valve blocks may be stacked or ganged side by side, and each used to control a machine part. Each valve block has a solenoid actuated valve to control flow of fluid such as air into a piston and cylinder assembly to move a part of the machine. The air flow is adjustably throttled by a needle valve in either the forward stroke or return stroke of the machine part. The needle valve has a normal at-rest position and may be moved in two directions toward opening and toward closing to establish a variable orifice in the valve block. First and second line shafts extend transversely to all of the various valve blocks for actuating the needle valves in the several valve blocks. Such actuation includes for each valve block first and second drive trains from the line shafts to the needle valve member with first and second clutches in the first and second drive trains and selectively actuable for opening and closing movements of the valve member.
The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
