›The design of the present application is directed…

The design of the present application is directed to a supply and exhaust block for a manifold solenoid valve, the supply and exhaust block being positionable on a side end surface of a manifold of a manifold solenoid valve to simultaneously supply and exhaust compressed air to and from a plurality of pilot-operated directional control valves on the manifold through a port provided in the lower half thereof. In addition, in the upper part of the supply and exhaust block, an external, small-diameter pilot port for supplying and exhausting a pilot fluid used to drive each pilot-operated directional control valve is provided and a silencer for arresting sound emitted during the supply and exhaust of the pilot fluid is mounted on the top surface of the supply and exhaust block.

FIG. 1 is a top, front and left side perspective view of supply and exhaust block for manifold solenoid valve embodying our new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a rear elevational view thereof;

FIG. 4 is a top plan view thereof;

FIG. 5 is a bottom plan view thereof;

FIG. 6 is a right side elevational view thereof;

FIG. 7 is a left side elevational view thereof;

FIG. 8 is a top, front and left side perspective view thereof, shown in use with the solenoid transfer valve which is shown in broken lines and forms no part of the claimed design; and,

FIG. 9 is a bottom, rear and right side perspective view thereof.
