Definitions

  • the invention relates to a connection device.
  • the individual line strands preferably produce a shortest connection between this central line and the further fluid passage point that can be assigned in each case, and preferably run in a direction perpendicular to the central line.
  • the blocking parts preferably in the form of so-called ball expanders, which can be inserted into the respective strands of the connecting lines that are not required formed, the connection line that is not required in the base body can be safely blocked with the functional component and, with regard to the established sealing connection, depending on the purposes for which the connection device according to the invention is to be used, additional sealing devices such as O-sealing rings, which are fundamentally prone to failure, are omitted on the part of the base body, which in turn helps reduce costs.
  • additional sealing devices such as O-sealing rings, which are fundamentally prone to failure
  • connection device solution according to the invention is particularly suitable for controlling channels and channel connections, preferably in the form of control lines, for example in the form of so-called LS lines in control blocks of mobile work equipment and machines that can be loaded with pressures of up to approx. 400 bar.
  • the connecting strand arranged on the output side of the functional component as part of a connecting line can be provided as a direct tank connection to the basic component; However, it can also serve as a continuation control line in the high-pressure area, provided that several connection devices and their components are combined to form functional groups.
  • Both the basic component and the basic body are preferably designed in the form of valve or flange blocks which can be connected to one another in a releasable manner, for example by means of a screw connection.
  • the base body 12 according to the representation according to FIG Fig. 1 two further fluid passage points P 1 and P x , which can be connected to one another with the correspondingly assigned fluid passage points P ' 1 and P' x in the basic component 10 in a fluid-carrying manner via the functional component 14.
  • There is also a locking part 16 (see also even Fig. 3 ), which blocks the respective fluid passage point P ' 2 , P' 3 , P ' n ... P' x-1 in the basic component 10, so that the relevant passage points remain unaffected by the functional component 14.
  • Both the basic component 10 and the basic body 12 are designed in the manner of valve or flange blocks which can be connected to one another in a flange-like manner to form an overall system.
  • the lower housing wall 18 of the flange-like base body 12 forms the blocking part 16, which in this respect covers the fluid passage points P ' 2 , P' 3 , P ' n ... P' x-1 in a blocking manner.
  • Radial widenings 20 are provided at the relevant fluid passage points of the basic component 10, which allow the insertion of a sealant, preferably in the form of an O-sealing ring 22, the respective O-sealing ring 22 being inserted before the flange-like connection between the body 12 and the basic component 10 is made.
  • the respective sealing means therefore ends in the form of the O-sealing ring 22 with at least part of its overhead outer contour on a flange side in the form of the lower housing wall 18 of the base body 12 in the area of the additional fluid passage points P ' 1 , P' 2 , P 'that can be assigned. 3 , P ' n ... P' x in the connected state of the base body 12 and the base component 10 and is in sealing contact with this wall 18.
  • passage P x , P ' x another passage could be selected on the output side, such as a combination P x-1 / P' x-1 .
  • a total of four different base bodies 12 would therefore be necessary to control four fluid passage points P ' 1 , P' 2 , P ' 3 and P' n on the inlet side, all of which are similar and in this respect also in FIG Fig. 2 are provided with the same reference numerals, but still differ in the design of the internal fluid-carrying piping and the connection geometry with regard to the further fluid passage points P 1 , P 2 , P 3 , P n ... P x .
  • connection device solution according to the invention shown below, it being noted in advance for clarification that the respective fluid passage points mentioned are not as in FIGS Figures 1, 2, 4 and 5 shown in principle, characterize the respective block image in a linear arrangement one behind the other, but rather that these can be arranged in groups also randomly distributed, as can be seen from the Fig.
  • a central line 30, preferably running horizontally, is now provided in the base body 12, which replaces the large number of previously differently arranged connecting lines in the flange-like base body 12.
  • the functional component 14 is in turn connected into the central line 30; that was previously represented in the manner of a black box in the Fig. 5 is shown in the design of a 2/2-way switching valve, which can be controlled by means of an electromagnetic device, for example in the form of a proportional magnet and in the Fig. 5 is shown in the through-connected position.
  • the blocking element solution presented is inherently self-sealing, so that the already described and customary O-sealing rings 22 can also be dispensed with, at least in the area of the blocking parts 16 used.
  • the blocking part 16 is introduced at a different point, i.e. within a different connecting strand, this can be easily implemented by simply inserting the independent blocking part 16 as a repetitive component into the desired wiring harness 32 to be occupied.
  • a step-like widening 42 can be provided in this, on which the blocking part 16 can then be supported with its bottom side for the spreading process described.
  • the mentioned ball expander solution for realizing the respective locking part 16 fulfills all of the requirements set out above.
  • the installation space required by the ball expander primarily only requires a small diameter step 42, as explained, and the sealing solution mentioned can also be subjected to high pressures physically from two sides without failure.
  • the blocking part 16 in the form of the ball expander can be attached and installed quickly and in a process-stable manner in the assignable line strands 32. This is with the previous sealing solutions, as exemplified in the Fig. 3 are not possible.
