- the invention has the object based, an accumulator of the generic type under consideration create, in contrast, by improved operating characteristics especially in areas of minimum volume the gas space of the store.
- a trough mounted on the trough is provided which concentrically extends to the longitudinal axis of the storage enclosure and with a second movable valve member is connected, which is at a given Smallest value of the volume of the gas space exceeding movement of the trough with a stream of Hydraulikfluidum in the oil chamber locking, second valve seat cooperates, opens up the advantageous Possibility, even the smallest value of the volume of the gas space corresponding end position of the trough with the aid of an oil-side valve to control.
- the used construction, in which the bellows the outside of a gas side Surrounding open trough is beneficial in several ways. As the whole Interior of the trough is available as part of the gas space is reached one optimal ratio between total size of the storage enclosure and volume of the gas space. While at the top of the beginning mentioned, known pressure accumulator sufficient volume of the gas space can only be realized that one for the end plate of the Metal bellows a sufficient stroke in the storage enclosure allows what leads to the mentioned overload problems of the bellows, can in the Invention of the extension of the bellows corresponding stroke of the closure body be made practically arbitrarily small. In other words said, the storage case can be shaped so that it after a short time Stroke movement of the trough forms a mechanical stop because the entire interior of the trough as gas volume available stands.
- the bellows are protected in this way not only against overstretching, but, as it surrounds the outside of the trough, the bellows is included in the gas space prevailing overpressure also mechanically on the outside supported on the entire length of the trough This in turn allows the Build-up of the gas pre-charge pressure even before starting up the accumulator, i.e. before the hydraulic system is connected on the oil side. If the latter the case is and once the operating pressure is built up in the oil room, is controlled by the outflow of Hydraulikfluidum from the oil chamber Valve maintained pressure balance at the bellows.
- the trough is circular cylindrical shaped, and the depth of the trough Is dimensioned so that its serving as a valve member bottom as a movable circular valve disc cooperates with a valve seat, the the inner wall of the storage housing is formed.
- an O-ring to form an annular Be provided sealing surface.
- the valve lifter also has a guiding function in the stroke movement of the Balges, so that a perfect fit of serving as Veritilglied trough floor at the valve seat and thus a perfect locking of the valve guaranteed are.
- the bellows works in equilibrium, can be a lightweight construction of the bellows, which is not only for weight reduction, but also leads to a particularly good response.
- FIGURE shows a longitudinal section of the embodiment of the Pressure accumulator.
- the illustrated embodiment of the pressure accumulator is in particular intended for use in electrohydraulic brake systems and has a memory housing designated as a whole by 1.
- This has a substantially nikzytinderförmigen main part 3, on the one hand by a welded bottom cover 5 and on the other hand by a welded, flat curved end cap 7 is closed.
- a central hydraulic connection 9 with passages 11 for Inlet and outlet of a hydraulic fluid to the oil chamber 13 within the Storage enclosure 1 is provided.
- a centrally located Gas filling opening provided which is closed by a plug 15 and it allows, by filling with a compressible gas in the adjacent Gas space 17 of the storage enclosure 1 a desired gas pre-charge pressure to produce, for example, by filling with nitrogen.
- a metal bellows 19 which has a circular cylindrical shape has and is firmly connected at one end to the bottom cover 5.
- Outer diameter of the metal bellows 19 is slightly smaller than the inner diameter of the cylindrical main part 3 of the storage enclosure 1.
- An his bottom end 5 opposite free end is the metal bellows 19 sealed by a closure body in the form of a trough 21.
- This is circular cylindrical in the embodiment shown shaped and has an outer diameter which is slightly less than the inner diameter of the metal bellows 19.
- the trough 21 is at its open End 23 with an outwardly folded, flange-like edge 25 am associated free end of the metal bellows 19 attached so that the side wall 27 of the trough 21 along the inside of the trough surrounding Metal bellows 19 extends and the interior of the metal bellows 19 only with the narrow annular space 29 between the outside of the side wall 27 of the trough 21 and the inside of the metal bellows 19 a part of Oil space 13 forms.
- the gas space 17 has a much larger volume, because inside the storage case 1 as the gas space not only the annulus 28 on the outside of the metal bellows 19 and the upper end cap. 7 adjacent room is available, but also the entire Interior of the trough 21.
- the hydraulic connection 9 is associated with a double-acting oil valve 31, the two the flow of Hydraulikfluidum through the passages 11 in each mutually opposite flow direction blocking or releasing valve units, by movements of the metal bellows 19 and thus of the trough 21 are controllable when the metal bellows 19 due to pressure differences in the oil chamber 13 and the gas space 17 contracts or pulls out and the trough 21 a corresponding Movement along the central longitudinal axis 33 of the storage housing 1 executes.
- the depth of the trough 21 is dimensioned so that when unloaded metal bellows 19, for example, if both ⁇ lrauml 3 and 17 gas space are depressurized, the trough bottom 35 to near the inner wall 37 the bottom lid 5 extends.
- the trough bottom 35 is a circular valve plate designed with the adjacent inner wall 37, as assigned Valve seat is designed, which forms one of said valve units.
- Valve seat is designed, which forms one of said valve units.
- to Formation of sealing surfaces are an O-ring 39 on the radially outer Edge of the trough bottom 35 and an O-ring 41 on the inner wall 37 of the Bottom cover 5 is provided, wherein the O-rings 39 and 41 respectively in corresponding Ring grooves are added. Due to the due to Diameter of the trough 21 conditional, relatively large radial Distance of the sealing surfaces of the central longitudinal axis 33 is a large area Seal and thus a very safe locking of the valve ensured.
- the second valve unit has a valve body 43, which has an on Trough bottom 35 attached valve lifter 45 together with the trough 21 movable is.
- the valve stem 45 extends through a central bore 47 in the bottom cover 5 from the storage case 1 out.
- the valve body 43 acts with a formed in the hydraulic connection 9 valve seat 49th together and has an attachable to the valve seat O-ring 50.
- the trough 21 moves at a contraction the metal bellows 19 due to an overpressure state in the gas space 17th opposite the oil chamber 13 with its serving as a valve plate trough bottom 35 to the inner wall 37 of the bottom cover 5, so that the O-rings 39 and 41 for engagement with corresponding surfaces of the valve seat or valve disk come and a drain of Hydraulikfluidum through the passages 11th is blocked from the oil chamber 13.
