Ford Air Bypass Valve Diagram - Thermactor Inlet, Outlet & Vent Ports (A6002-H)

This document is a technical line-art schematic (Ford figure reference A6002-H) showing cutaway and external views of three styles of air bypass/diverter valves used in an engine's Thermactor-type secondary air injection system. The upper-left cutaway view identifies the valve's inlet, outlet, polyester silencer, and the air bypass/relief exhaust port (vent). The upper-right cutaway view shows a similar valve with its vacuum nipple on top, inlet and outlet ports, and a lower connection for a remote dump. The bottom view is an external perspective drawing of a third valve style, labeling the inlet, outlet, and exhaust port (vent). A reader can learn where air enters and exits each valve type, where vacuum control is applied, where excess air is vented (through the polyester silencer or exhaust/vent port), and how a remote-dump style valve differs from a vented style. No year, model, engine, torque values, or part numbers other than the figure code A6002-H are shown. The document was uploaded to a 1995 Ford Bronco gallery, and nothing in the drawing contradicts that application, though the drawing itself states no applicability.
