Definitions
- the invention relates to a hydraulic accumulator with a piston which is movable in the axial direction in the accumulator housing and separates a gas side from a fluid side of the accumulator housing, on the circumference of which guide elements are provided for interaction with the wall of the accumulator housing and at least one sealing element which is in the axial direction towards the Guide elements offset, is arranged in the peripheral portion of the piston located between them.
- Piston accumulators of this type are commercially available and are widely used in hydraulic systems for a variety of tasks, for example for energy storage, emergency actuation, leakage oil compensation, volume compensation, shock absorption, pulsation damping and the like.
- the invention has for its object to provide a hydraulic accumulator of the type under consideration, which is distinguished from the prior art by an improved long-term operating behavior.
- this object is achieved according to the invention in that between the guide element which is closest to the piston side adjoining the fluid side and the sealing element which follows in the axial direction and is offset in the axial direction to the gas side, a pressure compensation channel opens at the piston circumference, which Piston forms a fluid path to the fluid side, and that a device reducing its passage cross section is provided in the pressure compensation channel.
- the starting point of the invention is that it has been found that dirt particles which are contained in the hydraulic oil located on the fluid side can have a negative effect on the long-term behavior of the hydraulic accumulator, more precisely the operational behavior of the sealing and guiding system between the piston circumference and the inner wall of the accumulator housing ,
- hydraulic accumulators of the prior art there is a pressure difference between the fluid side and the space located on the piston periphery between the guide element at the fluid-side end of the piston and the next sealing element in the axial direction due to the movement of the piston. Due to this pressure difference, there is a small volume flow across the guide element into the space between the guide element and the sealing element.
- the device effecting the reduction of the passage cross section of the pressure compensation channel preferably reduces the passage cross section so much that the effect of a particle filter results due to the narrowing of the cross section. Even a minimal volume flow through the pressure equalization channel, as it results for the pressure equalization during movements, does not result in the transport of dirt particles into the space on the piston circumference behind the guide element.
- a throttle device can be provided as the device reducing the passage cross section, for example a nozzle inserted into the pressure equalization channel with a correspondingly small nozzle opening, which acts as a particle filter.
- a porous filter element inserted into the pressure compensation channel can be provided as the device that narrows the cross section.
- the guide element closest to the fluid side of the piston is arranged closely adjacent to the fluid-side end of the piston and is guided by a guide band with an at least approximately formed dirt wiper lip extending to the end of the piston. This additionally prevents dirt particles, which may have already become lodged on the inner wall of the housing, from being overrun during piston movements.
- the guide band having the dirt wiper lip is designed as a rectangular ring seated in an annular groove of the piston circumference with a wiper lip extending radially on the outside on one side thereof and tapering towards its end edge.
- FIG. 1 shows a broken longitudinal section of a piston accumulator according to an exemplary embodiment of the invention, only the section of the accumulator housing in which the piston is located being shown, and FIG. 2 shows a part drawn on a greatly enlarged scale compared to FIG. 1 Longitudinal section of a piston guide element of the embodiment of FIG. 1 in the form of a rectangular ring with a protruding dirt wiper lip.
- FIG. 1 of the exemplary embodiment of the hydraulic accumulator to be described in the form of a piston accumulator, only the section of the accumulator housing 1 in which the piston 3 is located is shown.
- the gas side 5 is usually filled with nitrogen gas, while the fluid side 7 usually contains hydraulic oil during operation.
- the effective sealing and guiding system between the circumference of the piston 3 and the inner wall of the storage housing 1, which prevents media transfer from one piston side to the other piston side and forms a piston guide when the piston 3 moves, has several components provided on the circumference of the piston 3 on.
- a guide element in the form of a guide band 9 adjacent to the fluid-side end of the piston 3, a first piston seal 1 located at an axial distance therefrom approximately in the central region of the piston 3 1, a second piston seal 15 offset in relation to this in the axial direction against the fluid-side end 13 of the piston 3 and a guide element in the form of a guide band 17 which is offset even further against the end 13 of the piston 3.
- the bore 21 opens out on the circumference of the piston in the space between the guide band 17 and the piston seal 15 following in the axial direction. This room is designated 23.
- the invention provides for a narrowing of the passage cross section of the channel 19.
- this device is formed by a nozzle 25 which is inserted into the mouth of the bore 20 of the channel 19 at the end 13 of the piston 3.
- the nozzle bore 27 is chosen so small that it acts as a particle filter, so that no particles that have a larger dimension than the bore 27 can get into the space 23 via the channel 19.
- a filter element could be inserted into the pressure compensation channel 19, preferably in its bore 20.
- the guiding band 17 is additionally designed as a wiper element, the construction of which re can be seen from Fig. 2.
- this scraper element as the base part, which performs the function of the piston guide in cooperation with the inner wall of the housing 1, has a rectangular ring 29 which is mounted in an annular groove 31 machined into the circumference of the piston 3.
- the outer ring surface 33 of the rectangular ring 29 forming the guide surface is extended in the axial direction to form a wiper lip 35. This extends over an axial length that is somewhat greater than half the axial length of the rectangular ring 29, see FIG. 2.
- FIG. 2 As can also be clearly seen from FIG.
- the lip 35 tapers, starting from its root on the rectangular ring 29 , up to the end edge 37 with a taper angle ⁇ , which in the example shown is about 10 degrees with respect to the axial direction.
- ⁇ which in the example shown is about 10 degrees with respect to the axial direction.
- the radial thickness of the lip 37 at its root adjoining the rectangular ring 29 is somewhat less than half the radial thickness of the rectangular ring 29.
- the rectangular ring 29 and the scraper lip 35 formed integrally with it are made of an elastomeric material, so that the rectangular ring 29 can be snapped into the annular groove 31 on the piston 3 and the lip 35 extends flexibly and projecting , As can be seen from FIG. 1, the lip 35 extends over an end-side circumferential section 39 of the piston 3 which is somewhat reduced in outer diameter and extends into the region of the fluid-side end 13. Due to the space formed in section 39 between the piston 3 and the lip 35, the latter can resiliently nestle against the inner wall of the housing 1, as a result of which the lip 35 achieves an optimal scraper effect.
- the guide band 9 shown on the left in the direction of view of FIG. 1 can be configured or replaced by the guide band 17 shown on the right.
