ABSTRACT:
A mechanical control valve that can automatically direct the flow of fluid between two output lines. The control valve has a housing with a fluid inlet, a first outlet and second outlet. The valve also has a poppet that allows fluid to flow out of the first outlet when in a first position and through the second outlet when in a second position. The poppet is normally in contact with a mechanical timing switch. When fluid initially flows into the housing inlet, the poppet directs the fluid to the first outlet. The fluid activates the mechanical timing switch which releases from the poppet. When the fluid no longer flows through the valve, a spring moves the poppet into the second position. At the same time, the mechanical timing switch begins to move back into contact with the poppet. An orifice controls the movement of the switch, so that there is a time delay between the moment the fluid pressure in the valve drop, to the point when the poppet is pushed back to the first position. If fluid is reintroduced into the inlet during the time delay, the poppet will direct the fluid to the second outlet.
