Description

July 21, 1959 L. D. ORSER 2,895,507
` RRESSURE: ACCUMULATOR Filed Aug. 24, 1955 ZE- ZZUF LHNPQNLE Unser' .s .f l:2,895,507 i rod 29 maintains the ball member 27 in alignment with the valve seat 26a and permits only a substantially linear path of movement.
An adjustable pressure relief valve 32 is carried by the plates 18, and 19 and communicates with the inside ofthe` tank toy prevent the pressure therein from rising above apredetermined amount.
In operation, the pressure tank 10 is given a charge of compressed air to a predetermined amount, say 50. pounds, and then tluid to be sprayed is pumped into` the tank through the conduit 24 against the air pressure already therein. During the charging of the tank with compressed air, the oat valve assembly will take the position as seen in Figure 1 in closing the inlet-outlet 16. While iluid is shown in the very bottom of the tank -10 in Figure l, it will be understood that initially'no liquid will be present.
'When the `spray liquid is pumped into the pressure tank 10, the level of the liquid will rise above the float member 28 of the oat valve assembly 15 to maintain the inlet-outlet 16 open as seen in Figure 2. The liquid obviously compresses the air to a considerably greater pressure, say 150 pounds, and the air will not mix with the liquid, but will remain in the upper portion of the tank as illustrated. v
As indicated by the diagonal lines in the tank 10 above the liquid level in Figures l and 2, the greater number of lines in Figure 2 illustrate a greater pressure in the tank when charged with liquid. A
During the spraying operation, when the liquid will be discharged through the conduit 25, the pressure of course, will gradually decrease, and as the level of the liquid falls below the top of the float member 28, the oat valve assembly 15 will descend until the ball member 27 seats on the valve seat 26a. Thus, an extremely small amount of liquid may remain in the bottom of the tank, but there will also be a minimum of 50 pounds pressure remaining in the tank so -that the last portion of the liquid discharged from the tank is effectively sprayed.
In view of the foregoing, it is seen that the float valve arrangement maintains a minimum pressure in the tank 10 while allowing substantially all of the spraying liquid to be discharged therefrom without further pumping operations. Also, it is seen that at all times a proper relationship between the spraying liquid and the compressed air is maintained, and the initial air in the accumulator does not mix `with the liquid so as to gradually escape from the tank. Once charged with compressed air to 'outside said tank extending axially from said tank inletoutlet leading to a liquid source and a liquid outlet, a valve seat provided on said inlet-outlet, and a valve assembly having a spherical member defining a valve face for coacting with the valve seat, a float member connected to said spherical member and being within the conlines of said tank, a guide rod extending downwardly from said spherical member in the conlines of said conduit for guiding said member along a linear path, a guide plate in said conduit slidably receiving said guide rod, and an adjustable stop on said rod coacting Wtih said plate to restrict the linear movement of said spherical mem-` ber, said valve assembly permitting the entering and exit- Y ing of liquid and preventing the exiting of compressed tank having an inlet for admitting compressed air thereto, a liquid inlet-outlet in the tank bottom, a valve seat provided on said inlet-outlet, and a valve assembly having a valve member dening a valve face coacting with the valve seat, a float'member connected to said valve member and being within the connes of said tank, a guide rod extending downwardly from said valve member and outwardly of said tank, and means outside said tank slidably receiving said guide rod in axial alignment with said inlet-outlet for guiding said valve member along a linear path.
K 3. A pressure accumulator including a single chamber pressure tank for holding compressed air and liquid, saidA tank having an inlet for admitting compressed air thereto, a liquid inlet-outlet in the tank bottom, a Valve seat provided on said inlet-outlet, and a valve assembly having a valve member defining a valve face coacting with the valve seat, a oat member connected to said valve member and being within the contines of said tank, a guide rod extending downwardly from said valve member and outwardly of said tank, means outside said tank slidably receiving said guide rod and maintaining said the desired extent, the tank may be used repeatedly withguide rod in axial alignment with said inlet-outlet for guid-v ing said valve member along a linear path, and an adjustable stop on said rod, said stop being disposed beneath said means slidably receiving said rod and coacting therewith to restrict the linear movement of said valve member, said valve assembly permitting the entering and exiting of liquid and preventing the exiting of compressed air.
