a partition disposed within the valve body, said partition having a hole therethrough and said cooperating piston includes a big piston disposed below said partition and a small piston disposed above said partition within an upper cylinder sleeve, said small piston having a bottom engaging the partition hole.
2. The system according to claim 1 further comprising a water release tube disposed inside the flush valve and located in a middle of the upper cylinder sleeve and extending to the water vessel outlet, a check valve being disposed inside the water release tube.
3. The system according to claim 1 wherein said big piston, small piston, upper cylinder sleeve, and partition divide the valve body into a lower cavity, an upper cavity and a normal pressure cavity.
4. The system according to claim 3 further comprises a normal pressure opening disposed in said normal pressure cavity and said small piston include an opening in the bottom thereof communicating with said upper cavity.
5. The system according to claim 4 wherein said open valve includes an open valve body with an inlet connected with an outlet of the flush valve, said open valve body includes a water release hole connected to the normal pressure cavity, and said open valve includes a spring loaded handle having a side covering and sealing the open valve body inlet.
6. The system according to claim 1 further comprising a combination valve disposed between the infill valve and the water vessel inlet, said combination valve including a pressure-controlled valve disposed in a manner shutting of the vessel inlet when the water vessel is discharging water and an air-in device disposed in a manner filling air into the water vessel when water is filled into the water vessel.
7. The system according to claim 6 wherein said pressure-controlled valve includes an infill cavity, a water pressure cavity, an infill piston and a pressure-controlled spring, the infill cavity being connected respectively with the inlet duct and the outlet duct of the combination valve; the water pressure cavity being connected with the outlet of the combination valve.
8. The system according to claim 7 further comprises a through hole partition disposed between the infill cavity and the water pressure cavity and the infill piston is disposed inside the water pressure cavity on which is set a piston rod, which goes through the partition through hole and reaches into an outlet duct with the push of the pressure-controlled spring with and end forming a seal with the outlet duct.
9. The system according to claim 8 wherein a spout is disposed inside the outlet duct of the combination valve, the spout having a necked bottom and an air-in ball valve is disposed in a ring shaped cavity between the outlet duct and the spout, the ball valve forming an air-in device with the spout.
10. The system according to claim 6 further comprising an anti-siphon ball valve disposed in a combination valve inlet duct, the anti-siphon ball valve opening when the pressure in a water supply line is equal or lower than atmospheric pressure.
11. The system according to claim 10 further comprising a check ball valve disposed in a channel between the connecting valve inlet duct and a combination valve outlet duct, the check ball valve shutting off when pressure in the combination valve outlet duct is higher than pressure in the combination valve inlet duct.
12. A pressurized flush system comprising:
a pressure water vessel, having an inlet and an outlet;
an infill valve;
an open valve;
a flush valve disposed within said pressure water vessel and in fluid communication with said infill valve and said open valve, said flush valve comprising:
a hollow valve body;
cooperating pistons controlling water discharge from the water vessel outlet, said cooperating pistons being disposed within said hollow valve body; and
an outer flank surrounding the vessel outlet and defining an annulus outlet therebetween, the flank including a normal pressure water release hole and a ring shaped check valve is disposed in said annulus outlet below the normal pressure water release hole.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A device for the capture and payout of an in sink water spray hose, said spray hose having a first end connected to a water service line and a second end connected to an in-sink spray nozzle, said device being positioned between said first and second ends and comprising a clamp for releasably attached said device to said spray hose proximate the first end thereof, a housing having a length and width and a substantially open top and a weighted pulley wheel rotatable within said housing and movable along said length, said weighted pulley being characterized as being freewheeling as to not be appended to side walls of said housing, having a diameter greater than said width of said container and having a track diameter smaller than said weighted pulley diameter to substantially prevent said spray hose from dislodging from said weighted pulley once seated thereon.
2. The device of claim 1 wherein said weighted pulley is of sufficient means as to urge said spray hose into said container.
3. The device of claim 1 further comprising a plurality of rollers in spaced apart relationship positioned across said substantially open top for guiding said spray hose from and to the container of said housing.
4. The device of claim 3 wherein said plurality of rollers are selectively removable from said housing.
5. The device of claim 1 further comprising a plurality of rollers positioned within said housing and oriented substantially parallel to said width for reducing friction of said spray hose as it moves within said housing.
6. The device of claim 1 wherein said housing is sized such that the distance between the point of connection of said water line and said first end of said spray hose to said water nozzle is approximately equal to the maximum length of spray hose residing within said housing.
