Abstract
Abstract A faucet having a cartridge employing a cam and plunger type of closure means adapted to regulate the flow of fluid therethrough. The plunger, which is in communication with the faucet inlet and is urged away from its seat by the incoming fluid, is restricted in movement by a cam cooperating with a handle to thereby regulate the flow of fluid through the faucet.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
166 words
A faucet comprising: a. a housing having an interior chamber adapted to receive a valve cartridge, said housing having a fluid inlet and outlet, b. a valve cartridge inserted within the interior chamber of said housing between said inlet and outlet, said cartridge including: 1. a base having an inlet port in communication with said fluid inlet; 2. a plunger freely positioned in said base in proximity to said inlet port, said plunger adapted to be displaced relative to said inlet port to allow fluid under pressure to pass therethrough; 3. a centerpiece enclosing said base and plunger, said centerpiece having a plurality of outlet ports in communication with said inlet port and said chamber; 4. a stem rotatably positioned in said centerpiece, said stem having a variable depth cam in one end thereof cooperating with said plunger whereby rotation of said stem permits said plunger to be displaced relative to said inlet port to thereby control the quantity of fluid passing through said inlet port.
Claim 2
Dependent Claim
166 words
A faucet comprising: a. a housing having an interior chamber adapted to receive a valve cartridge, said housing having a fluid inlet and outlet, b. a valve cartridge inserted within the interior chamber of said housing between said inlet and outlet, said cartridge including: 1. a base having an inlet port in communication with said fluid inlet; 2. a plunger freely positioned in said base in proximity to said inlet port, said plunger adapted to be displaced relative to said inlet port to allow fluid under pressure to pass therethrough; 3. a centerpiece enclosing said base and plunger, said centerpiece having a plurality of outlet ports in communication with said inlet port and said chamber; 4. a stem rotatably positioned in said centerpiece, said stem having a variable depth cam in one end thereof cooperating with said plunger whereby rotation of said stem permits said plunger to be displaced relative to said inlet port to thereby control the quantity of fluid passing through said inlet port.
Claim 3
Dependent Claim
31 words
A faucet as defined in claim 1 wherein said inlet port is tapered and one end of said plunger has a chamfered end cooperating therewith to form a valve closure means.
Claim 4
Dependent Claim
34 words
A faucet as defined in claim 2 wherein said variable depth cam is of arcuate kidney shaped configuration and wherein the other end of said plunger has a rounded end cooperating with said cam.
Claim 5
Dependent Claim
16 words
A faucet as defined in claim 1 and further including a handle affixed to said stem.
Claim 6
Dependent Claim
30 words
A faucet as defined in claim 1 wherein said cartridge has a threaded portion cooperating with a threaded portion in said housing to thereby secure said cartridge to said housing.
Claim 7
Dependent Claim
19 words
A faucet as defined in claim 1 wherein said base, plunger, centerpiece and stem is formed of plastic material.
Claim 8
Dependent Claim
34 words
A faucet as defined in claim 1 further including a stop pin projecting from said stem, an arcuate slot formed in said base adapted to receive said pin to limit rotation of said stem.
Claim 9
Dependent Claim
16 words
A faucet as defined in claim 1 wherein said base, plunger, centerpiece ans stem are cylindrical.
Claim 10
Dependent Claim
17 words
A faucet as defined in claim 1 wherein said outlet included a spout extending from said housing.
Claim 11
Dependent Claim
144 words
A faucet comprising: a. a housing having an interior chamber adapted to receive a valve cartridge, said housing having a fluid inlet and outlet, b. a cylindrical valve cartridge inserted within the interior chamber of said housing between said fluid inlet and outlet, said cartridge including: 1. a cylindrical base having an inlet port in communication with said fluid, said inlet port having a tapered portion forming a valve seat, 2. a plunger freely positioned in said base inlet port having a chamfered end cooperating with said inlet port to form a valve closure means, said plunger being vertically guided in said base and adapted to be displaced away from said base by incoming fluid under pressure, 3. a cylindrical centerpiece enclosing said base and plunger, said centerpiece having a plurality of horizontal outlet ports in communication with said inlet port and said chamber;
Claim 12
Dependent Claim
144 words
A faucet comprising: a. a housing having an interior chamber adapted to receive a valve cartridge, said housing having a fluid inlet and outlet, b. a cylindrical valve cartridge inserted within the interior chamber of said housing between said fluid inlet and outlet, said cartridge including: 1. a cylindrical base having an inlet port in communication with said fluid, said inlet port having a tapered portion forming a valve seat, 2. a plunger freely positioned in said base inlet port having a chamfered end cooperating with said inlet port to form a valve closure means, said plunger being vertically guided in said base and adapted to be displaced away from said base by incoming fluid under pressure, 3. a cylindrical centerpiece enclosing said base and plunger, said centerpiece having a plurality of horizontal outlet ports in communication with said inlet port and said chamber;
Claim 13
Dependent Claim
81 words
a cylindrical stem rotatably positioned in said centerpiece, said stem having a variable depth cam in one end thereof which cooperates with said plunger whereby said plunger is urged against said cam by the incoming fluid under pressure whereby rotation of said stem permits said plunger to be displaced toward said inlet port overcoming said incoming fluid under pressure to thereby control the distance between said plunger and inlet port thus regulating the quantity of fluid passing through said inlet port.
Claim 14
Dependent Claim
81 words
a cylindrical stem rotatably positioned in said centerpiece, said stem having a variable depth cam in one end thereof which cooperates with said plunger whereby said plunger is urged against said cam by the incoming fluid under pressure whereby rotation of said stem permits said plunger to be displaced toward said inlet port overcoming said incoming fluid under pressure to thereby control the distance between said plunger and inlet port thus regulating the quantity of fluid passing through said inlet port.
Claim 15
Dependent Claim
34 words
A faucet as defined in claim 10 wherein said variable depth cam is of arcuate kidney shaped configuration and wherein the other end of said plunger has a rounded end cooperating with said cam.
Claim 16
Dependent Claim
16 words
A faucet as defined in claim 10 and further including a handle affixed to said stem.
Claim 17
Dependent Claim
30 words
A faucet as defined in claim 10 wherein said cartridge has a threaded portion cooperating with a threaded portion in said housing to thereby secure said cartridge to said housing.
Claim 18
Dependent Claim
19 words
A faucet as defined in claim 10 wherein said base, plunger, centerpiece and stem is formed of plastic material.
Claim 19
Dependent Claim
34 words
A faucet as defined in claim 10 further including a stop pin projecting from said stem, an arcuate slot formed in said base adapted to receive said pin to limit rotation of said stem.
