Definitions
- the invention relates to a pressure medium accumulator with a housing, the interior of which is divided into three chambers, the first chamber being filled with a gas and being separated by a first media separation element from the second chamber which is filled with a liquid and by a second media separation element is separated from the third chamber, which is also filled with a liquid and is connected to a hydraulic connection
- Such a pressure medium reservoir is known from DE-OS 29 10 554.
- the first media separation element is formed by a metallic bellows, while the second media separation element is formed by an elastic partition.
- This object is achieved in that the second media separation element is formed by a metallic piston which delimits a ventable space in the housing.
- FIG. 1 shows a first embodiment of the pressure medium reservoir according to the invention in axial section
- Fig. 2 shows a second embodiment of the pressure medium reservoir according to the invention in a representation corresponding to FIG. 1.
- the first embodiment of the pressure medium reservoir according to the invention shown in FIG. 1 has a housing 1, the interior of which is divided into three pressure spaces or chambers 2, 3, 4.
- the first chamber 2 is formed by the interior of a first media separation element 6, which preferably consists of a thin-walled metallic bellows, which is connected pressure-tight to the housing 1 on the one hand and is closed by a plate 13 on the other hand.
- the first chamber 2 can a filling connection (not shown) provided in the housing 1 can be filled with a gas which is generally under high pressure.
- the third chamber 4 is formed, in which a hydraulic connection 5 opens.
- a radial recess formed on the circumference of the piston 8 delimits with the wall of the housing 1 a space 9 which is connected to the atmosphere via bores 14.
- the space 9 is sealed off from the second chamber 3 and the third chamber 4 by means of an elastic sealing ring 11 and 12, respectively. If brake fluid is used to fill the second chamber 3, it is conceivable to use the space 9 mentioned above with a brake fluid container connect to.
- a particularly viscous liquid can also be used to fill the second chamber 3, which, however, does not then enter the brake fluid container, but e.g. B. is derived into the atmosphere.
- the first chamber 20 is not, as described above, formed by the interior of the first media separation element 60, but is delimited between the wall of the housing 10 and the first media separation element or bellows 60.
- the interior of the bellows 60 forms the second chamber 30, into which a cylindrical guide part 15 assigned to the housing 10 projects, into which the second media separation element 70 or the piston 80 is guided and the third chamber 40 is formed.
- the space 90 between the piston 80 and the cylindrical guide part 15 mentioned in connection with FIG. 1 is made similar to the second chamber 30 and the third chamber 40 by means of each, similar to the embodiment shown in FIG of a seal 110, 120 sealed and connected to the atmosphere via a schematically indicated channel 18.
- a hydraulic connection 19 is formed in the piston 80 between the second and the third chamber 30, 40, in which a check valve 17 closing towards the third chamber 40 is inserted.
- the check valve 17 serves to fill or refill the separation liquid into the second chamber 30.

Abstract
L'invention concerne un accumulateur d'agent de pression comprenant un boîtier (1) dont l'intérieur est subdivisé en trois compartiments (2, 3, 4), le premier compartiment (2) étant rempli d'un gaz et séparé du deuxième compartiment (3) par un premier élément séparateur d'agents (6). Ce deuxième compartiment, rempli d'un liquide, est séparé par un deuxième élément séparateur d'agents (7) du troisième compartiment (4), également rempli d'un liquide et en liaison avec un raccord hydraulique (5). L'invention vise à séparer efficacement les agents à l'intérieur de l'accumulateur d'agent de pression pour en augmenter notablement la sécurité de fonctionnement. A cet effet, le deuxième élément séparateur d'agents (7) est constitué d'un piston métallique (8, 80) qui délimite, dans le boîtier (1), un compartiment (9, 90) qui peut être purgé.
