PRESSURE: CONTROL FITTINGS Filed Jan. 15, 1954 INVENTORS MAI M PRESSURE CONTROL FITTINGS Ralph E. Bletcher and Irving A. Ward, Los Angeles,
Calif assignors to Modern Faucet Mfg. Co., Los Angeles, Calif., a corporation of California Application January 13, 1954, Serial No. 403,762
3 Claims. (Cl. 137-119) This invention relates to an improved pressure control fitting and is more particularly directed to a pressure controlled fixture for selectively controlling flow of water through one of two outlets from a single inlet. The invention is an improvement over the fitting set forth in the patent to E. H. Bucknell and R. E. Bletcher No. 2,314,071, March 16, 1943.
It is an object of this invention to provide means adapted for use in a fitting having more than one outlet for controlling fiow through the outlets.
It is a further object of this invention to provide such a device wherein a back siphon from any of said outlets to the water supply is eliminated.
It is a further object of this invention to provide a pressure control fitting which will accomplish the above mentioned puiposes While eliminating flow of sand and foreign matter to one of said outlet reducing wear and consequent leakage experienced in the above identified patented device.
It is a further object of this invention to reduce the number of moving parts to reduce the possibility of the device jamming or becoming stuck.
It is a further object of this invention to produce a device which will function at a much lower water pressure.
It is still a further object of this invention to provide a device which will function in any given position such as vertical, horizontal or even inverted.
It is still a further object of this invention to construct a unit which will provide greatly increased tolerance in manufacture.
Other objects and advantages will be readily apparent from the following description,
In the drawings:
Figure 1 is a sectional view of a unit embodying this invention in the position wherein water is directed out the spout outlet.
Figure 2 is a view similar to Figure 1 with the unit in the position wherein water is directed out the spray outlet.
Figure 3 is a view similar to Figure 2 showing the elements of the unit in full.
Figure 4 is a perspective view of the unit components.
Figure 5 is a perspective view of the carrier.
Figure 6 is a further perspective view of the water.
A sink fixture 19 includes hot and cold water branches 12 and 14 having a spout outlet 16 that is open to the atmosphere, and a spray outlet 18 that is valve controlled. Fitted into the spout outlet is an internally threaded sleeve 29 having an internal flange 22 forming a shoulder between the spout outlet 16 and water supply branches.
The spray outlet branch 18 is internally threaded to receive carrier 24 which is of a smaller external diameter at its upper end than the internal diameter of sleeve at its lower extremity and said carrier terminates short of the internal flange or shoulder 22.
The upper extremity of the carrier has a chamber 26 formed therein communicating with the spray outlet through water passage 28.
nited States Patent 0 Secured between shoulder 22 and the upper extremity of the carrier 24 isa wafer 30. The wafer is formed of a metal ring 32 coated with a suitable resilient material 34. The upper surface of the wafer bears against shoulder 22 while the under surface has three resilient legs 36 which are spaced an equal distance from one another and bear against the upper extremity of the carrier 24. In this manner the water supply is always in communication with chamber 26 through the space between legs 36. Also the wafer is always in contact with shoulder 22 preventing sand and foreign particles wearing down the shoulder which would result in excessive leakage through the spout outlet when water is directed through the spray outlet.
The wafer is provided with a tapered bore 38 therethrough which receives valve head 40. The valve head 49 is on one extremity of valve stem 42 which carries piston 44 at its opposite extremity. Piston 44 has three spaced legs 46 thereon which engage wafer 30 upon upward movement of the piston.
In operation when the spray outlet is opened water flow through chamber 26 creates a pressure difierential on the piston 44 lowering same in the chamber. This engages valve head 40 with the tapered bore or valve seat 38 in water 30 shutting oif flow to the spout outlet.
When flow is terminated through said spring outlet the pressure diiferential raises piston 44 and thereby unseats valve head 40, permitting flow through the spout outlet.
When flow is terminated through either outlet the valve head seats preventing back siphonage from the spout outlet. If a back siphonage should be formed in the spray outlet the piston 44 would raise, unseating valve head 40 venting chamber 26 through the spout outlet and breaking the siphon.
While what hereinbefore has been described is the preferred embodiment of this invention, it is readily apparent that alterations and modifications can be restored to without departing from the scope of this invention, and such alterations and modifications are intended to be included within the scope of the appended claims.
We claim:
1. A pressure control fitting for use in a chamber having a pair of opposed outlets and an inlet comprising: a shoulder formed in the first outlet, a carrier projecting from the second outlet and terminating short of said shoulder, a wafer having a surface bearing against said shoulder and spaced legs engaging the upper extremity of said carrier whereby flow is permitted from outside said carrier to the interior thereof, means forming a bore in said wafer communicating said first and second outlets and valve means responsive to flow through said second outlet for closing off said bore.
2. A pressure control fitting for use in a chamber having a pair of opposed outlets and an inlet comprising: a shoulder formed in the first outlet, a carrier projecting from the second outlet and terminating short of said shoulder, a wafer having a surface bearing against said shoulder and resilient spaced legs engaging the upper extremity of said carrier whereby flow is permitted from outside said carrier to the interior thereof, means forming a bore in said wafer communicating said first and second outlets and valve means responsive to flow through said second outlet for closing off said bore.
3. A pressure control fitting for use in a chamber having a pair of opposed outlets and an inlet comprising: a shoulder formed in the first outlet, a carrier projecting from the second outlet and terminating short of said shoulder, a wafer having a resilient surface bearing against said shoulder and resilient spaced legs engaging the upper extremity of said carrier whereby flow is permitted from outside said carrier to the interior thereof, means forming a bore in said wafer communicating said first and second outlets ahd valve means responsive to flow through said second outlet for closing 'ofl said bore.
