Abstract: A valve component for a faucet includes a substrate comprising a base material and a strengthening layer provided above the substrate in an amount sufficient to improve abrasion resistance of the substrate, the strengthening layer comprising tantalum. A layer including amorphous diamond is provided above the strengthening layer. The amorphous diamond has sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.

Abstract: A faucet includes a first valve plate comprising a base material and a strengthening layer provided above the base material. An amorphous diamond material is provided above the strengthening layer. The amorphous diamond material has a coefficient of friction that is lower than that of diamond-like carbon and has a hardness that is greater than that of diamond-like carbon.

Abstract: A wear resistant component for a faucet valve includes a substrate comprising a base material and a strengthening layer provided above the substrate in an amount sufficient to improve abrasion resistance of the substrate. The strengthening layer includes at least one material selected from the group consisting of tantalum, chromium, zirconium, and tungsten. The wear resistant component also includes a layer that includes amorphous diamond provided above the strengthening layer, the amorphous diamond having sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.

Abstract: A method of forming a wear resistant component includes providing a base material, depositing a strengthening layer on the base material, and vapor depositing an amorphous diamond layer on the strengthening layer.

Abstract: A fill valve assembly for a water tank such as a toilet tank. The fill valve assembly includes a head portion containing a valve mounted on top of a vertical water outlet tube and a float which moves vertically along the outlet tube to control the opening and closing of the valve. The float is vertically adjustable without removal or disassembly of the valve assembly in order to adjust the tank water level to a preselected position. The float includes an inverted cup-shaped structure which moves vertically along the outlet tube in response to any change in the water level. The valve contains a flexible main valve disk held in a closed position against a valve seat by water pressure in a control chamber to prevent the flow of water into the tank, and is moved to an open position upon venting of the control chamber. A pilot valve controls the pressure in the control chamber and, therefore, the movement of the main valve disk.

Abstract: A sliding component, particularly a disk valve plate. The sliding component includes a multi-layer surface structure comprising a strengthening layer harder than the substrate material, and an amorphous diamond top layer.

Abstract: A medical liquid administration set is provided with a check valve which is configured to relieve excess pressure downstream from the check valve. The check valve includes a resilient valve disc and a valve seat, which engages the disc when the valve is closed. The administration set includes primary and secondary liquid sources connected through a Y-connector to a pump, which pumps liquids sequentially from the first and second sources to a patient. The check valve is disposed in the set between the Y-connector and the primary liquid source and is in its closed position with the valve disc on the valve seat when the liquid level in the secondary liquid source is higher than the liquid level in the primary source to thereby prevent backflow of liquid from the secondary source into the primary. The check valve is in its open position, allowing flow from the primary source to the patient when the liquid level in the secondary source has fallen to the level of liquid in the primary source.
