There is also a cen tral ‘port 407' in thestem plate which registers with the port 25 in the body member in all posi tions of the stern plate, and a smaller port 4| in radially spaced relation to the center port ar Fig. 5 is a plan view of the valve operating 20 ranged to register with the auxiliary port 32 in the backwash position of the stem plate and with Fig. 6 is a plan view of the valve body with the the auxiliary port 33 in the salt wash‘ or brine cover and stem plate removed and indicating dia position of the stem plate. The ports 31 and 39 . grammatically the pipe connections used incon previously mentioned are interconnected by a junction with the valve in a water softener instal 25 cored passage 42 in the stem plate. _ The operation of the valve as thus far described Figs. 7, 8, and 9, are top views of the stem plate can be understood by reference to Figs. 6 to 9. showing a portion thereof in horizontal section In the normal softening operation, the incoming on the line '|—'| of Fig. 1, Fig. 7 being the service raw water from the‘ pressure or supply port 25 position of the stem plate and Figs. 8 and 9 the .30 ?ows into the cover 2|, as should be clear from a backwash and salt wash or brine positions, respec study of Fig. 1, and the raw water leaves the valve tively; ' ‘ through the ports 38 and 29 and enters the top Fig. 10 is a view similarto Fig. 2, showing a of the softener S for passage downwardly through modi?ed or alternative construction; , _ the bed of water softening-material therein.

This ?ow valve opened preparatory to the shifting of the 40 continues until the water softener-‘requires re stem plate from one position to another, and generation, whereupon the operator, as will later Figs. 13 and 14 are sectional details of the valve appear, shifts the stem plate 23 to the backwash operating means on the lines |3--|37 and |4-|4 position shown in Fig. 8, 180° removed from the means; lation; , _ , V ~ 7 of Figs. 11 and 12, respectively.

During back .. wash the incoming raw water from the pressure or supply port 25 ?ows through communicating ports 38 and 3| out of the valve and into the bot shown bears a general resemblanceto that dis tom of the softener S for passage upwardly closed in McGill Patent 2,209,992, the reference through the bed of water. softening material so numeral 20 designating the stator or body mem 60 as to break up the bed preparatory to the salt ber of the valve on which a ‘cap or cover 2| is wash ?ow and also wash out from the top of the suitably secured, compressing a gasket 22 there tank whatever sediment accumulated on the top between to prevent leakage. ' The cover encloses the rotor or stem plate‘ 23, and this stern plate in its three operative positions-service, back-y wash, and salt wash or brine-controls the flow of water through the valve by providing a differ ent system of communication between the various parts in the body 20 in each of the three positions. It should be understood that although the valve is one especially designed for use in controlling the ?ow of ?uids to and from a zeolite water softener, the invention is not limited to that or any other specific application but is applicable of the bed during the softening operation. The water leaving. the top of the softener re-enters the valve through the communicating ports 29' v and 39 and flows through the passage 42 and out of the valve through communicating ports 31 and 30 to the drain. This ?ow is continued for a pre determined time, su?icient to thoroughly cleanse the bed and prepare it for the salt wash. During this interval raw water may be by-passed to the service system by virtue of the fact that the port 4| in the stem plate 23 registers with the port 32 and, hence, also with the port 28 communicating to valves generally.

The head 62 of the valve is'housed within a recess 66 in the bottom of the stem plate, so that there is nothing projecting below the plane of the stem plate that would come into contact with the gasket rings and interfere with the free turn ing of the stem plate. There are two ports 61 and 68 in the boss 65 parallel to the hole '64, and these ports as well as the end of the hole are '16 in a clockwise direction in order to cause the stem 48 to move downwardly to close the shut off valve 56 and open the relief valve 6|. It should be clear that the Valve 56 when left in the open. position shown in Fig. 1 can be set at a higher or lower elevation by rotation of the wheel 76 to regulate the flow of water used in the serv ice position and during back-washing. In many other valves with which we are familiar, a special closed by the head 62 when the valve is seated, as shown in Fig. 1.

After the stem plate in this pressure relief, assuming there are no open is moved from the service position to the back faucets in the system. Consequently there is no wash position, the shut-off valve 56 is opened appreciable wasting of Water.
