Abstract: A multiple coupling means for the production of a releasable connection between fluid lines for a fluid pressure medium and associated with a fluid pressure source, said lines being on the source side and fluid lines associated with at least one fluid load and placed on the load side, said coupling means comprises a first coupling part (12) having several first fluid ports (13) and a second coupling part (14) possessing several second fluid ports (15) for the fluid lines on the load side, the two coupling parts (12 and 14) being able to be shifted in a coupling operation into a working position (22) by being moved together in the direction of an installation axis (21), in which working position (22) mutually opposite joint faces (17 and 19) of the two coupling parts (12 and 14) engage each other and in which the two coupling parts (12 and 14) are secured by means of holding means to avoid accidental uncoupling, an actuating means (23) able to be operated manually is provided, by means of which the coupling pa

Abstract: A connection union for a fluid line (11) containing a fluid duct (14) has at least one signal conductor (16a and 16b) in the wall (15) of the fluid line (11) for the transmission of electrical and/or optical signal. The connection union a fluid line socket (23) and a holding device (25) for the fluid line (11) and at least one signal contact (31a; 31b) for the production of a connection with the at least one signal conductor (16a and 16b). The at least one signal contact (31a; 31b) is able to be slid in the insertion direction (28) of the fluid line (11; 68 through 71) and is provided with spring means (37) so that during a longitudinal movement of the fluid line (11) mounted on the connection union (10) the at least one signal contact (31a; 31b) remains connected with the at least one signal conductor (16a and 16b). Moreover the invention contemplates a suitable fluid line (11) and a fluid power means belonging to it.

Abstract: A connection member for a fluid line (2) defining a fluid duct (5) with stranded signal conductors (7a and 7b) in the wall (4) thereof for the transmission of electrical signals. The connection member has a female socket into which the fluid line (2) may be inserted and in which at least one signal contact (26a and 26b) is arranged, which at the end may stick into the at least one signal conductor (7a and 7b). The penetrating part (27) is constituted by a knife edge (27a) whose width is equal to the diameter of the signal conductor (7a and 7b) to be contacted and which splits the signal conductor 7a and 7b) on penetration from the end into an outer and an inner line limb.

Abstract: A plastic hose, and more particularly a pneumatic hose, is provided with at least two electrical conductors extending along the hose body. These conductors are in the form of strips (11 and 12) of a metallized braid of plastic material or of natural fiber with a spacing apart on the hose body (13). Accordingly high flexibility of the plastic hose (10) is achieved with satisfactory electrical conductivity of the strips ensuring safety as regards breakage.

Abstract: A sealing ring (12) has an annular principal body (15) responsible for its dimensional stability, such body having an annular groove on at least one axial side, in which groove a sealing body (16), consisting of rubber-elastic material, is held. The sealing body (16) has a sealing bead (24) projecting axially past the principal body (15). The capacity of the annular groove (25) is at least equal to the volume of the sealing body (16) so that the annular groove (25) is in a position of receiving the material of the sealing body (16) defining its sealing bead (24) during action on and deformation of the sealing bead (24).
