FLUID PRES SURE ACCUMULATQR v v Filed April 2, 1931 I Patented May 1932 PATENT OFFICE NEAL W. DOW, TOLEDO, OHIO, ASBIGNOR TO THE TOIQEDO MACHINE & TOOL COIPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO FLUID ranssuan accnuuna'ron Application filed April 2, 1981.' Serial 170. 527,226.
This invention relates to a fluid pressure accumulator adapted to be incorporated as a part of a fluid pressure line which may be used for various purposes.
The object of the invention is to provide means for maintaining the required pressure under conditions where the pressure creat ing means temporarily may be inactive or may develop pressure at a slower rate than it is being used. It is also desirable to prov vide a relief or safety valve or port to prevent the possible loading of the accumulator beyond its capacity- The invention, in its preferred form will be more particularly described in connection with the accompanying drawings, in which a Figure 1 is a plan view of accumulator; Figure 2 is a vertical section taken on the line 2-2 ofFigure 1; and
' Figure 3 is a side elevation of the accumulator: Y
The invention, in its present adaptation has been devised particularly for use in actuating a hydraulic clutch, although it is obviously capable of use in any pressure line. As illustrated in the drawings, the invention comprises a reservoir 5 having a cover 6 which is secured thereto by bolts 7 mother suitable means. While the system may be operated with a gaseous fluid, it is more positive in its action and more quickly responsive if -'the reservoir is partially filled with oil or other liquid, owing to the fact that liquids are substantially incompressible. A conduit 8 leads through the cover 6 and is ada ted to .be connected to a pump which disc arges through a conduit 9 into a cylinder 11 formed as a part of the cover 6. The conduit 8 is extended, as shown at 12, to the bottom part of the reservoir and its inlet end is provided.
with a strainer 13.
A piston 14 is operable within the cylinder 11 and is urged upwardly by a coil spring 15 seated within a pocket 16 which constitutes the end of the cylinder and which is 'rovided with a port 17 in its bottom and with lat-- eral ports 18 above the normal level of the liquid within the reservoir. I
As the liquid is pumped through the conduit 9 into the upper end of the cylinderll, while pressure is not being used, the cylinder accumulates a supply of liquid which is sub- ]ect to the pressure of the piston 14 under the influence of the compressed spring 15'. As the piston 14 is forced downwardly, an overload is prevented by relief ports 19 in the side of the cylinder, which allow the liquid to escape as they are uncovered and maintain the accumulator at its maximum capacity, as shown in Figure 2, until such time as the pressure line is used to operate a hydraulic clutch or other pressure operable device. A conduit 20 leads from the upper end of the cylinder to the point where the pressure is to be utilized and when the pressure operated device is released, the spent liquid is returned to the reservoir 5 through a conduit 21.
The reservoir 5 is adapted to be supplied with liquid through a filler mouth 10 and an air vent pipe 22 is provided in the cover 6 to permit variations in the level of the li uid within the reservoir.
When this accumulator is interposed in a pressure line, it permits the pump to operate continuously to build up or to accumulate liquid in thecylinder 11 so that the latter Will be in condition to operate at its potential capacity, while the pumpmay be temporarily stopped or may be supplying pressure at a slower rate than it is to be utilized.
This is of special importance in the operation of hydraulic clutches as used on power presses, since when a valve is turned to admit oil from the conduit 20 to the clutch, the operation of the latter is not dependent upon the simultaneous operation of the pump.
The pump may be driven only while the slide is'operatin While theslide is stationary,-
there is su cient liquid in the cylinder 11. to
ically one embodiment of the invention, it
is apparent that the' samemay be considerably modified without departing materially from the scope of the appended claims.
