Definitions
- the edge of the partition-forming diaphragm is not only clamped by the pulling elfort of said plate during the mounting but also compressed by the internal pressure during the inflation and by the pressure prevailing in the accumulator when the latter is in actual service.
- This last-named pressure tends to urge the marginal portion of the diaphragm by causing the distortion of the elastic plate.
- the clamping force is not constant but subordinate to the internal pressure
- the accumulator is particularly capable of withstanding a wide range of pressures, even of pulsatory character.
- FIGURE 1 illustrates diagrammatically a diaphragmtype hydraulic accumulator constructed according to the teachings of this invention.
- FIG. 2 is a partial cross-section showing a modification.
- the reference numeral 1 designates the casing of a hydraulic accumulator provided with a connecting union 2 and divided by a diaphragm 5 into two compartments 3 and 4 one containing a. gaseous medium under pressure and the other a liquid.
- This diaphragm 5 made of suitable elastomer comprises a lip 6 and a lateral portion 7 contacting the inner wall of the accumulator casing 1.
- the assembly comprising the accumulator casing 1, the connecting union 2 and the diaphragm 5 is advantageously of revolution about an axis 8; however, it will readily occur to anyone conversant with the art that the accumulator casing 1 may consist of two half-shells assembled for example by screwing, according to manufacturing requirements.
- This plate 10 comprises means for pressing the diaphragm against the casing, for example in the form of shoulders such as 19 and 22 (see FIG. 1) or a rounded edge 23 engaging a corresponding groove 24 formed in the diaphragm (FIG. 2).
- the pressure prevailing in the space 12 and on the diaphragm edge 6 is constantly equal to the pressure of the gaseous medium in compartment 3 and to that prevailing in the other, liquid-filled compartment 4.
- the clamping plate '10 comprises cylindrical portions 20 and 21 which cannot be distorted by the pressure prevailing in the accumulator. These cylindrical portions clamp the edge 6 with a constant torce resulting from the tractive effort exerted by the fastening member 13, irrespective of the pressure prevailing in the accumulator 1.
- the member 13 can be used as an inflation plug for introducing a gas into the upper compartment 3.
- a gasket 14 seals the joint between this gas-filled compartment and the atmospheric air surrounding the accumulator.
- Diaphragm type hydraulic accumulator according to claim 1, wherein a hole is provided in the upper part of said clamping plate for establishing communication between said free gap and said gaseous medium.
- Diaphragm type hydraulical accumulator according to claim 1, wherein said clamping plate comprises-in its lateral part a shoulder and a cylindrical portion contacting the edge of said diaphragm in the vicinity of said shoulder.
- Diaphragm type hydraulic accumulator according to claim 1, wherein said diaphragm has a groove and said clamping plate comprises a rounded edge engaged in said groove and a cylindrical portion contacting the edge of said diaphragm.
