Definitions

  • the invention relates to a method for filling a pressure medium accumulator with a housing, the interior of which is divided by a serving as a media separation element metallic bellows in two chambers, wherein the first chamber is filled with a gas and the second chamber with a liquid pressure medium and wherein in a hydraulic Connection a bottom valve is provided, the closing body is actuated by the media separation element and which allows filling of the second chamber with the pressure medium and prevents complete emptying of the second chamber.
  • the present invention relates to a device for filling a pressure fluid reservoir with a housing, the interior of which serves as a media separation element metallic bellows in two chambers is divided, wherein the first chamber is filled with a gas and the second chamber with a liquid pressure medium and wherein in a hydraulic connection, a bottom valve is provided, the closing body is actuated by the media separation element and filling the second chamber with the pressure medium allows and prevents complete emptying of the second chamber, wherein means for evacuating the second chamber, means for filling the second chamber with pressure medium, and means for filling the gas are provided in the first chamber, and wherein a connectable to the first chamber, the Gas supply serving first line and a second line connectable to the second line is provided, which is selectively connectable to a pressure medium source or a vacuum source.
  • Such a pressure fluid accumulator is known from international patent application WO 00/31420.
  • the closing body of the bottom valve is brought by the movement of the bellows in a position in which it performs the function of a hydraulic piston.
  • both damage to the bottom valve and an undesired discharge of pressure medium are effectively prevented, a significant increase in the reliability is guaranteed.
  • the cited publication are no indications as to how the previously mentioned chambers can be reliably filled with appropriate media, without the bellows is damaged.
  • a method for filling a pressure medium accumulator of the type mentioned is known.
  • the second chamber is first filled with a pressure medium, after which a gas is introduced into the first chamber.
  • the pressure medium is only partially displaced and serves, after the bottom valve has been closed, as a support for the bellows, so that damage to the bellows during the filling of the gas is avoided.
  • This object is procedurally achieved in that when filling the second chamber with the defined pressure medium volume of the path traveled by the bellows is sensed.
  • a device for opening or keeping open the bottom valve is provided.
  • the pressure medium reservoir to be filled according to the method according to the invention has a housing 1 whose interior is subdivided by means of a media separation element 2 into two pressure chambers or chambers 3, 4.
  • the media separation element 2 is preferably formed by a thin-walled metallic bellows, on the one hand pressure-tight manner with a lid 8 closing the housing 1 and on the other hand is closed by a plate 9.
  • the interior of the bellows 2 forms the first chamber 3, which can be filled via a filling connection 10 provided in the cover 8 with a gas which is generally under high pressure.
  • a hydraulic port 5 is formed, in which a bottom valve 6 is arranged, the closing body 7 protrudes into the second chamber 4.
  • the bottom valve 6 is preferably designed such that it on the one hand allows filling of the second chamber 4 with a pressurized fluid pressure medium, such as a brake fluid, and on the other hand prevents complete emptying of the second chamber 4.
  • a pressurized fluid pressure medium such as a brake fluid
  • a compression spring 11 located in the first chamber 3, a compression spring 11, the between the cover 8 and the aforementioned plate 9 is clamped and thus biases the bellows 2 in the direction of the bottom valve 6. This ensures that the pressure prevailing in the second chamber 4 hydraulic pressure is always higher than that prevailing in the first chamber 3 gas pressure.
  • a sensor device for sensing the movement of the media separation element 2, which is provided with the reference numeral 12, is provided in the gas-filled first chamber 3.
  • the sensor device 12 which may be formed, for example, as an inductive displacement sensor, is an independently manageable assembly, which can be used in an opening provided in the lid 8.
  • first pressure sensor 19 for monitoring the pressure medium filling pressure
  • second pressure sensor 20 for monitoring the level of the negative pressure applied by the negative pressure source 15
  • displacement sensor 21 for monitoring the movement of the device 16 for mechanically opening or keeping the bottom valve 6 open
  • the previously mentioned plate 9 is under the action of the compression spring 11 at a first stop (for example, at the bottom of the housing 1) and that the bottom valve 6 is closed.
  • This output state corresponds to a signal value of the displacement sensor 12, which is determined and stored.
  • the determined signal value is later used in operation to detect defects on the bottom valve 6.
  • the first chamber 3 is acted upon with low pressure (eg with compressed air up to 2 bar).
  • the second line 14 is connected by opening the associated shut-off valve 18 to the vacuum source 15 and the second chamber 4 evacuated.
  • the second chamber 4 is provided with a pressure medium provided for this purpose, preferably a brake fluid, completely filled under low pressure, wherein the bellows 2 is compressed by a small amount.
  • the pressure spring 11 or the gas pressure acting in the first chamber 3 then causes a slow outflow of the excess pressure medium volume until the bottom valve 6 closes. Since the closing body 7 of the bottom valve, the plate 9 closing the bellows 2 and the displacement sensor 12 are in contact with each other , the signal value of the displacement sensor 12, at which the bottom valve 6 closes, can be determined and stored.
  • a defined pressure medium volume is refilled, which corresponds to the system-related minimum requirements and the z. B. represents the volume value, which ensures a perfect function of the accumulator at the temperature of 120 ° C.
  • the bellows 2 is compressed or a movement of the plate 9 closing it up into a defined position, which corresponds to a third signal value of the displacement sensor 12.
  • the signal value is again determined and stored.
