Definitions
- the invention relates to a hydraulic accumulator, in particular bladder accumulator, with the features of the preamble of claim 1.
- Hydraulic accumulators of this type are commercially available. In one of the company Mannesmann Rexroth edited textbook "The Hydraulic Trainer", Bd.1, on page 165 a bubble memory of the type mentioned is shown and described.
- the valve assembly designed as a seat valve, wherein on the fluid space facing End edge of the connecting piece as a fixed valve seat a conical surface is formed, which with a corresponding conical surface on a valve plate the movable valve body cooperates.
- This is similar designed as the usual in valve-controlled internal combustion engines Control valves, i. the valve disk is located on a shaft which is suitable for the between the open position and closed position extending valve lift is guided in a valve guide as a valve carrier, which is part of the Connecting piece is.
- a pressure fluid accumulator (hydraulic accumulator) known with a housing, whose interior through a media-separating element is divided into two chambers, the first chamber with a gas and the second chamber is filled with a liquid and wherein a bottom valve is provided in a hydraulic connection, whose closing body by the media-separating element in the form of a Actuating plate of a bellows is actuated and filling the second chamber with liquid allows and complete emptying prevents the second chamber.
- the closing body through the media-separating element in a position can be brought, in which fulfills the function of a hydraulic piston is.
- the closing body has on its part of the separation plate of Federbalgaires facing a spherical actuating part on, so that in this respect a selective force peaks having force on the media separation element takes place on the closing body.
- the complete in the connecting piece guided known valve body needs about
- a Wear is subject, so this from time to time to the functional safety of the hydraulic accumulator to exchange for new ones are.
- FR 1 154 187 is a generic hydraulic accumulator, in particular Bladder accumulator, known with a storage enclosure, one in this arranged separating element, the one in the storage enclosure to a gas-side access separates adjacent gas space from a fluid space, which adjoins a fluid-side access, which fluidly Anschlut having, located in the connection piece valve carrier with fluid passage and with a plate-like, on its the valve carrier facing side to the valve stem towards tapered valve body, the on a power storage in the form of a compression spring in his the Fluid passage releasing open position biased and by a movement the separating element is movable into its closed position and the protrudes into said fluid space in said open position, wherein the valve body is integral, in particular integral part of the valve carrier, the along its outer circumference within the connecting piece in this is guided longitudinally movable.
- valve carrier moved against a stop in the connecting piece, which consists of a circlip.
- the valve carrier has only one fluid passage in the axial direction, the in a radially extending fluid passage in the manner of a in the valve body attached transverse bore opens, wherein the axially occidentalrekkende Fluid passage in the rest of the energy storage in the form of the compression spring is penetrated.
- the known solution builds complicated on, which increases the manufacturing costs and the reliability accordingly impaired.
- a further hydraulic accumulator solution is known especially in the form of a bladder accumulator, which is not is a valve plate solution with valve carrier in the indicated sense, but rather a piston valve solution in which the piston is used as a valve carrier should have the largest possible diameter opposite its installation length, so as to increase the rigidity of the closing valve, to the disadvantage of the known valve disc solutions with slim trained valve stem to meet in the overload range on the Pressure side of the memory of the valve plate in the valve seat in the form of Unintentionally pressed in connection piece (page 1, lines 102 - 108 GB 2 104 964).
- the tapered end part the carrier piston is detachably connected to this, for example with Help of a screw connection.
- a circlip and the piston-like valve body is known in this Solution via a stop of the connecting piece in the same kept safe; however, in contrast to the above French Font of the energy storage in the form of the compression spring below the valve body arranged.
- the solution known in turn also has only one fluid passage in the axial direction in the valve body, in the radial Fluid passage points in the piston-like valve body opens. Also the To this end known solution is also complex and expensive in the Production.
- a diaphragm accumulator is known as a hydraulic accumulator, in which in the connecting piece for fluid guidance a fluid guide part screwed diametrically to its longitudinal axis with multiple fluid passages is provided.
- the fluid guide part On its upper side, the fluid guide part a plate-like guide surface, the flow diversion of the fluid from the fluid passages to the fluid side of the hydraulic accumulator makes.
- the pertinent fluid guide surface is immovable integral part of the set in the connection piece of the diaphragm storage fluid guide part.
- the outer diameter of the guide surface is chosen such that that from the side of the connecting piece ago a screwing possible is, so that the guide surface is not od in the manner of a valve.
- the marginal boundary surfaces of the connecting piece to the interior of the Memory can spill over.
- a fluid guide part can also already be due to the geometric Dimensions of the plate-like guide surface a valve function, as in the solutions described above, even after appropriate modification thus not perceive.
- the invention is based on this prior art, the task To create a hydraulic accumulator that comparatively easy and is inexpensive to produce while increased reliability and has the maintenance intervals at longer intervals.
- this object is according to the invention achieved in that a plurality of fluid passages in the form of longitudinal bores in the valve carrier diametrically to its longitudinal axis and to the longitudinal axis the valve body are arranged opposite to each other, that the Fluid passages bounded inwardly by the valve stem of the valve body are that the energy storage below the piston-like valve body is arranged between this and the connecting piece and that the valve body with valve carrier in machining machining as a turned part is designed.
