Single valve ready to use sprayer
View Patent ↗A sprayer head assembly for dispensing a chemical stored within a container comprises a body having a bore and a valve moveably positioned at least partially within the bore. The sprayer head assembly includes passages for the carrier fluid and the chemical. A vent passage is also provided. The valve selectively closes and opens the carrier fluid, chemical and vent passages. The valve is configured to move in a side to side motion which is generally transverse to a longitudinal axis of the assembly.
1. A sprayer head assembly, comprising:

a supply fluid connection; and
a valve positioned in the bore, comprising:
an outer wall defining a cylindrical periphery;
a first passage through the cylindrical periphery and in communication with an interior of the valve;
a second passage through the cylindrical periphery and in communication with an interior of the valve; and
a rib seated in the longitudinal groove of the bore and slidable therein;
wherein the valve is movable within the bore between an open position wherein the first passage is in communication with the internal passage and the second passage is in communication with the supply passage and a closed position wherein the internal passage is not in communication with the first passage and the supply passage is not in communication with the second passage.
2. A sprayer head assembly, comprising:
a sprayer head, comprising:
a bore;
a supply passage defining a longitudinal axis of the sprayer head assembly and in communication with an interior of the bore;
a container connection portion;
a supply fluid connection portion; and
a control valve in sliding engagement with the bore, wherein the control valve is slidable between an open position and a closed position in a direction transverse to the longitudinal axis of the sprayer head assembly.
3. The sprayer head assembly of claim 2 wherein each of the sprayer head, container connection portion, and supply fluid connection portion comprise polypropylene.
4. The sprayer head assembly of claim 2 , wherein the sprayer head further comprises a vent passage in communication with the bore.
5. The sprayer head assembly of claim 2 , wherein the container connection portion further comprises a rotatable coupler.
6. The sprayer head assembly of claim 2 , further comprising:
a longitudinal groove in the bore; and
a rib on the control valve configured to fit in the longitudinal groove of the bore.
7. The sprayer head assembly of claim 2 , wherein the control valve further comprises:
a first passage; and
a second passage.
8. The sprayer head assembly of claim 2 , wherein the control valve further comprises:
a valve surface; and
a recess in the valve surface in communication with the first passage.
9. The sprayer head assembly of claim 8 , wherein the recess comprises a generally triangular shape.
10. The sprayer head assembly of claim 8 , wherein the valve surface comprises a generally inclined surface inclining along a supply fluid path.
11. A sprayer head assembly, comprising:
a sprayer head, comprising:
a bore;
a supply passage defining a longitudinal axis of the sprayer head assembly and in communication with an interior of the bore;
a longitudinal groove in the bore;
a container connection portion;
a supply fluid connection portion;
a control valve slidable in the bore between an open position and a closed position; and
a rib on the control valve, wherein the rib is seated in the longitudinal groove of the bore and slides therein as the control valve slides in the bore.
12. The sprayer head assembly of claim 11 , further comprising:
a chemical passage in communication with the bore;
a supply passage in communication with the bore;
a first passage in the control valve, wherein the first passage is in communication with the chemical passage in an open position; and
a second passage in the control valve, wherein the second passage is in communication with the supply passage in an open position.
13. The sprayer head assembly of claim 12 , wherein the first passage further comprises a metering orifice.
14. The sprayer head assembly of claim 11 , wherein the control valve is moveable along an axis transverse to the longitudinal axis of the sprayer head assembly.
15. A sprayer head assembly, comprising:
a sprayer head, comprising:
a bore;
a supply passage defining a longitudinal axis of the sprayer head assembly, wherein the supply passage is in communication with an interior of the bore; and
a longitudinal groove in the bore;
a container connection portion, comprising:
a rotatable coupler; and
a washer;
a chemical passage in communication with the bore;
a supply fluid connection portion, comprising:
a supply fluid connection portion rotatable coupler; and
a supply fluid connection portion washer;
a supply passage in communication with the bore;
a control valve, comprising:
a wall defining a cylindrical periphery of the control valve, the wall in sliding engagement with the bore;
a rib on an exterior of the wall, wherein the rib is seated in the longitudinal groove of the bore and slides therein as the control valve is moved between open and closed positions;
a first passage, wherein the first passage is in communication with the chemical passage in an open position;
a valve surface on an interior of the control valve;
a recess in the valve surface and in communication with the first passage; and
a second passage, wherein the second passage is in communication with the supply passage in an open position.
