Abstract

A cartridge valve 10 for a faucet has a shell 12 housing a movable valve plate 22 and an operating stem 20 able to control the plate 22 by operating mechanism 17. A bottom member 19 has hot and cold water inlets 54 and 56. A fixed valve plate 23 is seated on the bottom member 19 and has hot and cold water outlets 50 and 52 in communication with the inlets 54 and 56. The shell has orienting notches 42 and 44 with notch 44 having a removable prong 46 therein. Bottom member 19 has two orienting tabs 38 and 40 with tab 40 having a groove 48 that receives prong 46 to assure a correct first orientation of the bottom member to shell 12. The prong 46 can be removed if the bottom member 19 is desired to mount to the shell 12 in a second reversed position that is 180° rotated from the first orientation.

Claims

1. A cartridge for a mixing valve faucet that regulates the flow rate and mixing proportions of liquid from two supply inlets to said faucet, said cartridge characterized by:

a main shell;

an operating mechanism mounted to said shell;

a movable valve element operably connected to said operating mechanism;

a separate reversible bottom member mounted to said shell;

said bottom member mounting a fixed valve seat to cooperate with said movable valve element;

a joint means for mounting said bottom to said shell;

an orienting and indicating means for assuring a single standard orientation of said bottom member; and

means for overriding said orienting and indicating means for deliberate reversing of the orientation of said bottom member.

4. A cartridge as defined in claim 1 further characterized by:

said orienting and indicating means including a male member mounted on one of the shell and bottom member, the other of the shell and bottom member having a receptor for receiving said male member at one orientation of the bottom member with respect to the shell.

5. A cartridge as defined in claim 4 further characterized by:

said male member being removable to allow a reverse orientation of said bottom member with respect to said shell.

6. A cartridge as defined in claim 4 further characterized by:

said male member extending in a notch in one of said shell and bottom member;

a second notch without a male member is radially located opposite said male member;

said other of said shell and bottom member has first and second radially opposite tabs, said first tab having a receptor for said male member and said second tab not having a receptor for said male member to assure a correct first orientation of said bottom member to said shell.

7. A cartridge as defined in claim 6 further characterized by:

said male member being removable from said notch to allow said bottom member to be rotated 180°

to a reverse orientation and be joined to said shell.

2. A cartridge as defined in claim further characterized by:

said joint means positioned and cooperating with said shell and bottom to mount said bottom to said shell in at least two rotated positions only when said means for overriding is effected.

3. A cartridge as defined in claim 2 further characterized by:

said joint means being constructed to mount said bottom in two different rotated positions communication of said supply inlets to be inverted with said fixed valve seat at said respective two positions only when said means for overriding is effected.

8. A cartridge for a faucet valve that regulates the flow rate of liquid from a supply inlet to said faucet, said cartridge characterized by:

a main shell;

an operating mechanism mounted to said shell;

a movable valve element operably connected to said operating mechanism;

a separate reversible bottom member mounted to said shell;

said bottom member includes a fixed valve seat to cooperate with said movable valve element;

an orienting and indicating means for assuring a single standard orientation of said bottom member; and

means for overriding said orienting and indicating means for deliberate reversing of the orientation of said bottom member.

9. A cartridge as defined in claim 8 further characterized by:

said bottom member being constructed to be mounted to said shell in a first rotated position when said orienting and indicating means is effective;

said bottom member being constructed to be mounted to said shell in a second rotated position only when said overriding means is effected.

10. A cartridge as defined in claim 8 further characterized by:

said orienting and indicating means including a male member mounted on one of the shell and bottom member, the other of the shell and bottom member having a receptor for receiving said male member at one orientation of the bottom member with respect to the shell.

11. A cartridge as defined in claim 10 further characterized by:

said male member being removable to allow a reverse orientation of said bottom member with respect to said shell.

12. A cartridge as defined in claim 10 further characterized by:

said male member extending in a notch in one of said shell and bottom member;

a second notch without a male member is radially located opposite said male member;

said other of said shell and bottom member has first and second radially opposite tabs, said first tab having a receptor for said male member and said second tab not having a receptor for said male member to assure a correct first orientation of said bottom member to said shell.

13. A cartridge as defined in claim 12 further characterized by:

said male member being removable from said notch to allow said bottom member to be rotated 180°

to a reverse orientation and be joined to said shell.
