US Patent:

6354326, Mar 12, 2002

Filed:

Sep 14, 1998

Appl. No.:

09/152750

Inventors:

Tuan Van Le - Diamond Bar CA
Christopher A. Coppock - Laguna Niguel CA

Assignee:

Fluidmaster, Inc. - San Juan Capistrano CA

International Classification:

F16K 4702

US Classification:

137436, 137218, 137414, 137429, 137443, 138 42, 251126

Abstract:

A toilet fill valve includes a housing defining a water fill passage and a water inlet. A valve disposed in the passage divides the housing into a upstream portion and a downstream portion. A pressure regulator vertically oriented in the downstream portion of the housing has a spiral configuration providing a significant pressure drop in the water flow. Noise abatement is enhanced by pressure regulation which reduces the flow velocity, flow directors which inhibit turbulence, and energy drops provided in a downspout.

Filed:

Jul 13, 2001

Appl. No.:

09/905839

Inventors:

Tuan Le - La Mirada CA 90638

International Classification:

G01N 2100

US Classification:

3562373, 3562372, 3562374

Abstract:

A dynamic reflective spatial attenuator for use in an optical inspection apparatus. The attenuator takes the form of a two-dimensional micro-mechanical reflective array that, in the first operative position of a mirror element, reflects the desired scattered light toward a detector and, in the second operative position of a mirror element, reflects undesired scattered light into a light dump. The mirror arrays fast response and flexibility allows for changes during mid-scan to increase the defects or contaminants signal relative to the substrate surfaces signal.

Appl. No.:

10/014117

Inventors:

Tuan Le - Diamond Bar CA, US

Assignee:

Fluidmaster, Inc. - San Juan Capistrano CA

International Classification:

F16L021/00

US Classification:

285402, 285921, 285419

Abstract:

A quick coupler formed of two identical sectors that snap lock together in a radially inward direction relative to a central axis of an annular hole passing through the coupler. The coupler is in the form of a nut or housing for surrounding the ends of two conduits that are to be coupled. The annular hole extends between opposite end faces and has structure near each end face. The structure at one end of the annular hole comprises a flange for retaining a first conduit when the sectors are snapped surroundingly snapped together on the end of the first conduit. The structure at the other end of the annular hole has circumferentially spaced lugs for cooperation with bosses on the second conduit in a bayonet quick coupling fashion. The combination of the coupler with first and second conduits having cooperating structure enabling the coupler to join the conduits in sealed fluid communication. The method of use of the combination comprises snap fitting the sectors onto an end of the first conduit by radially inward pressure.

International Classification:

F16K 31/18

US Classification:

137426, 137436, 251126, 251127, 138 42

Abstract:

A fill valve for a toilet tank includes a multi-piece shank assembly. The shank assembly includes a first hollow member coupled with a second hollow member using a snap joint. The first hollow member has a tortuous outer surface, which together with the second hollow member forms a plurality of flow paths. The flow paths are configured to reduce water noise. The first and second hollow members are provided separately, resulting in simplified molding process and improved assembly automation.

International Classification:

E03D 1/00

US Classification:

4415, 4325, 137441

Abstract:

A dual flush valve is provided for refilling fluid in a toilet bowl. The dual flush valve includes a refill mechanism configured to refill the toilet bowl with a substantially same volume of refill fluid for both a full flush and a half flush, a first valve connected to the refill mechanism, the first valve operates to control flow of fluid into a bowl, a fluid input is connected to a first port of the first valve, and a fluid output is connected to a second port of the first valve. The level of fluid in the bowl is refilled to a same level for both a full flush and a half flush.

International Classification:

E03D 5/09

US Classification:

4410, 4325

Abstract:

A dual flush button assembly includes a unitary button with a full flush surface and a partial flush surface. Pressing the partial flush surface moves the button linearly to active a partial flush. Pressing the full flush surface rotates the button to activate a full flush. An extension member beneath the button is coupled to a link of a dual flush valve. The extension member is moved farther when the full flush surface is engaged. The button is configured to pivot with respect to a housing when the full flush portion is engaged.

Abstract:

A diverter valve including: an inlet port coupled to a refill tube; a first outlet port; a bowl refill tube coupled to the outlet port with its second end adjacent to a toilet tank overflow tube; a second outlet port; a central flow passageway providing a path of fluid communication between the inlet port and the first and second outlet ports, the entrance of the first outlet port and the entrance of the second outlet port being directly opposite one another in the central flow passageway; a poppet in the central flow passageway, the poppet having a raised position obstructing the first outlet port and a lowered position obstructing the second outlet port; an actuating arm, float member and rod coupled to the poppet, wherein movement of the float member translates downward motion of the rod into upward motion of the actuating arm and vice versa.
