Abstract
Abstract An alternator valve assembly particularly suited for below ground level use in septic systems for diverting flow from a single inlet to either of two separate outlets. The valve is comprised of a plastic housing which defines a valve chamber having an inlet, a pair of outlets, and valve plug seat means located in the housing adjacent each outlet. A rubber valve plug is adapted to be received in the valve chamber in one of the outlets to selectively block flow therethrough. The plug includes a sealing lip cooperable with the valve seat of the associated outlet and includes an elongated handle protruding outwardly of the valve housing to facilitate movement of the plug between blocking positions with each of the outlets. An outlet box defining a hollow outlet box chamber and having an exit area may be disposed in operative communication with each of the valve housing outlets. An elongated tube-like member extends upwardly from the valve chamber housing to ground level and the elongated handle for the valve plug extends upwardly through the tube-like member to substantially ground level. A cap or cover is closely received in or over the tube-like member at ground level. The elongated handle is longitudinally dimensioned to cooperate with the inner face of the cap or cover to prevent undesired dislodgement of the valve plug from blocking engagement with one of the valve chamber outlets due to system back pressures or the like.

Claim 1
Independent Claim
312 words
An alternator valve assembly adapted to be located some distance beneath a reference surface comprising in combination: a housing having a continuous side wall, a bottom wall and a top wall defining a hollow valve chamber, said housing including an inlet opening and at least two spaced apart outlet openings communicating with said chamber from outside of said housing, said top wall having a valve plug receiving opening and said outlets each having a valve seat area disposed adjacent thereto in said chamber; a valve plug receivable in said chamber through said plug receiving opening and movable through said receiving opening between separate blocking positions in said chamber for selectively blocking at least one of said outlets while allowing communication through said chamber between said inlet and the other of said outlets, said valve plug comprising a resilient body having a plug portion adapted to be received in said at least one outlet and a resilient sealing area adapted to sealingly engage the seat area associated with said at least one outlet; an elongated handle having one end operatively communicating with said valve plug to extend outwardly therefrom and outwardly from said housing through said plug receiving opening when said plug is in a blocking position with the other end of said handle adapted to be disposed adjacent said reference surface; means for defining a passage adapted to extend between said reference surface and said plug receiving opening in said housing top wall, said passage defining means being dimensioned to receive at least said handle therethrough; and, means for selectively closing said passage defining means adjacent said reference surface and including means positively cooperating with said handle other end to assist in maintaining said valve plug sealing area in sealing engagement with said at least one outlet seat area and to prevent dislodgement of said valve plug from a desired blocking position.
