Valve Actuation Control for Flush Urinal and Toilet Apparatus
First Claim
1. A flush apparatus for a flush system, comprising:
- a valve body having a water inlet for connecting to a water source to guide water to flow to said water inlet at a water-in direction, and a water outlet for connecting to the flush system; and
an actuation control, which comprises;
a cartridge valve comprising a cartridge housing stationary supported in said valve body at a position that a valve inlet of said cartridge housing is located at said water inlet and said valve outlet of said cartridge housing is located at said water outlet, and a control disc unit which is supported in said cartridge housing at said valve inlet thereof and is orientated transversely to the water-in direction for resisting water pressure from said water source, wherein said control disc unit is able to be driven to move between a closed position to close said valve inlet for blocking the water to pass through said valve inlet, and an opened position to open up said valve inlet for allowing the water passing to said water outlet through said valve outlet so as to complete a flushing cycle of the flush system.

Abstract
An actuation control for a flush system includes a cartridge valve being actuated between an opened position and a closed position to compete a flushing cycle. The cartridge valve includes a cartridge housing having a valve inlet for communicating with a water source and the valve outlet for guiding water to flow to the flush system, and a control disc unit which is supported in the cartridge housing at the valve inlet thereof and is orientated perpendicular to a water-in direction of the water for biasing against water pressure from said water source. At the closed position, the valve inlet is closed by the control disc unit for blocking the water to pass through the valve inlet. At the opened position, the valve inlet is opened up for allowing the water passing to the valve outlet so as to complete the flushing cycle of the flush system.

28. An actuation control for controlling volume of water used in a flushing cycle of a flush system, comprising:
-
a cartridge valve being actuated between an opened position and a closed position to compete said flushing cycle, wherein said cartridge valve comprises a cartridge housing having a valve inlet for communicating with a water source and said valve outlet for guiding water to flow to the flush system, and a control disc unit which is supported in said cartridge housing at said valve inlet thereof and is orientated transversely to a water-in direction of the water for resisting water pressure from said water source, wherein said cartridge valve is actuated at said closed position to close said valve inlet by said control disc unit for blocking the water to pass through said valve inlet, and at said opened position to open up said valve inlet for allowing the water passing to said valve outlet so as to complete said flushing cycle of the flush system; and a control processor operatively linked to said cartridge valve for controllably adjusting a time of said flushing cycle and water volume for said flushing cycle, wherein said control processor is activated in response to a presence of a user of said flush system to actuate said cartridge valve for controllably adjusting said time of said flushing cycle by moving said cartridge valve between said closed position and said opened position. - View Dependent Claims (29, 30, 31)

32. A method of controlling a flushing cycle of a flush system via a flush apparatus which comprises a valve body having a water inlet and a water outlet, comprising the steps of:
-
(a) providing a cartridge housing of a cartridge valve in said valve body and supporting a sealing disc of said cartridge valve in said cartridge housing at said valve inlet at a position that said sealing disc is orientated transversely to a water-in direction of a flow of water for biasing against water pressure from said water source; (b) retaining said cartridge valve in a closed position that said valve inlet is sealed and closed by a sealing disc of said cartridge valve in said cartridge housing; (c) actuating said cartridge valve from said closed position to an opened position that said sealing disc is moved to open up said valve inlet; and (d) after completing said flushing cycle of said flush system, actuating said cartridge valve back to said closed position from said opened position that said sealing disc is moved to seal and close said valve inlet. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 45, 46, 47, 48, 49, 50)
