Plumbing valve

Claim 2

In combination a flush tank for supplying liquid to a toilet bowl to flush said bowl and a filling device for the delivery of a predetermined amount of liquid to said flush tank, said filling device comprising: A. a liquid supply line; B. a valve to which said liquid supply line is connected in order to supply liquid to said valve and which has a moving part to open or close said valve to allow or prevent passage of liquid through said valve; C. means for metering the amount of liquid flowing through said valve; and D. means for actuating said moving part to close said valve dependent on the passage of a predetermined amount of liquid through said metering means in which the means for actuating said moving part comprises: i. a cam with a substantially circular outer surface excepting for a notch in said cam surface; and ii. a swing lever and swing lever stop mounted on said cam so as to co-act with said valve to prevent the valve from immediately reseating after being actuated.

Claim 3

The combination of claim 1, in which the means for metering the amount of liquid flowing through said valve comprises: i. a housing having a liquid flow passage therethrough, and ii. a turbine wheel contained with said housing.

Claim 4

The device of claim 1, in which said valve comprises: A. a housing having a liquid flow passage formed therethrough and having a circular valve seat; B. a spherical ball designed to form a sealing relationship with said valve seat; C. a valve follower having a portion which rides on the cam surface and another portion which contacts the spherical ball; D. a flange on said valve follower located so as to co-act with the swing lever located on the cam; and E. a spring positioned so as normally to maintain a sealing relationship between said circular valve seat and said spherical ball.

Claim 5

The device of claim 1, wherein a filter means is located in the liquid flow passages at a position prior to the introduction of the flow into the turbine housing.

Claim 6

The device of claim 1, wherein the device is made principally of a plastic material.

Claim 7

The device of claim 1, in which said metering means comprises: A. a turbine wheel; B. a circular housing containing said turbine wheel; C. an inlet pipe tangentially located on the circumference of said housing; D. an outlet pipe tangentially located on the circumference of said housing; and E. a second outlet located on the circumference of said housing.

Claim 8

The combination of claim 4, wherein a filter means is located in an inlet conduit and is connected to the turbine housing at a position prior to the inlet conduit''s introduction into the turbine housing.

Claim 9

The combination of claim 4, wherein a filter means is located in an inlet conduit.

Claim 10

In combination, A flush tank for supplying liquid to a toilet bowl to flush said bowl and a filling device for the delivery of a predetermined amount of liquid of said flush tank, said filling device comprising: A. a liquid supply line; B. a valve to which said liquid supply line is connected in order to supply liquid to said valve and which has a moving part to open or close said valve to allow or prevent passage of liquid through said valve; C. means for metering the amount of liquid flowing through said valve; and D. means for actuating said moving part to close said valve dependent on the passage of a predetermined amount of liquid through said metering means; in which the means for metering the amount of liquid flowing through said valve comprises: i. a housing having a liquid flow passage therethrough, and ii. a turbine wheel contained within said housing; and the means for actuating said moving part comprises: i. a substantially circular cam formed with a notch in the outer circumference thereof, and driven by said turbine wheel.

Claim 11

In combination, A flush tank for supplying liquid to a toilet bowl to flush said bowl and a filling device for the delivery of a predetermined amount of liquid of said flush tank, said filling device comprising: A. a liquid supply line; B. a valve to which said liquid supply line is connected in order to supply liquid to said valve and which has a moving part to open or close said valve to allow or prevent passage of liquid through said valve; C. means for metering the amount of liquid flowing through said valve; and D. means for actuating said moving part to close said valve dependent on the passage of a predetermined amount of liquid through said metering means; in which the means for metering the amount of liquid flowing through said valve comprises: i. a housing having a liquid flow passage therethrough, and ii. a turbine wheel contained within said housing; and the means for actuating said moving part comprises: i. a substantially circular cam formed with a notch in the outer circumference thereof, and driven by said turbine wheel.

Claim 12

In combination, a flush tank for supplying liquid to a toilet bowl to flush said bowl and a filling device for the delivery of a predetermined amount of liquid to said flush tank, said filling device comprising: A. a liquid supply line; B. a valve to which said liquid supply line is connected in order to supply liquid to said valve and which has a moving part to open or close said valve to allow or prevent passage of liquid through said valve; C. means for metering the amount of liquid flowing through said valve; and D. means for actuating said moving part to close said valve dependent on the passage of a predetermined amount of liquid through said metering means in which the means for metering the amount of liquid flowing through said valve comprises: i. a housing having a liquid flow passage therethrough, and ii. a turbine wheel contained within said housing; iii. an inlet pipe located tangentially to the turbine wheel on the circumference of said housing; iv. an outlet pipe located tangentially to the turbine wheel on the circumference of said housing; and v. a second outlet located on the circumference of said housing.

Claim 13

In combination, a flush tank for supplying liquid to a toilet bowl to flush said bowl and a filling device for the delivery of a predetermined amount of liquid to said flush tank, said filling device comprising: A. a liquid supply line; B. a valve to which said liquid supply line is connected in order to supply liquid to said valve and which has a moving part to open or close said valve to allow or prevent passage of liquid through said valve; C. means for metering the amount of liquid flowing through said valve; and D. means for actuating said moving part to close said valve dependent on the passage of a predetermined amount of liquid through said metering means in which the means for metering the amount of liquid flowing through said valve comprises: i. a housing having a liquid flow passage therethrough, and ii. a turbine wheel contained within said housing; iii. an inlet pipe located tangentially to the turbine wheel on the circumference of said housing; iv. an outlet pipe located tangentially to the turbine wheel on the circumference of said housing; and v. a second outlet located on the circumference of said housing.
