摘要： PURPOSE: To provide a method and an apparatus for executing automatic control for making a platform or the like especially for a motor vehicle reach a desired level through the use of hydraulic supporting cylinders at a relatively low cost in such a way that the method and the apparatus are adaptable to usage in areas in which levelling operation is conventionally executed manually. CONSTITUTION: Hydraulic supporting cylinders 1-4 are extended for levelling a body, for example, a platform or vehicle part. As soon as one of the cylinders reaches a supporting position while moving out, further extension of this cylinder is temporarily discontinued. After extension of the last supporting cylinder, i.e., that the cylinder which is the last to reach the supporting position, has been discontinued, the levelling operation is completed by only operating the other supporting cylinders which had previously reached the supporting position. The other supporting cylinders are further extended until the level position is reached.

摘要： PROBLEM TO BE SOLVED: To couple a fluid between a compensating vessel and transformer, even under a large lateral force. SOLUTION: A compensating device of a transformer for railway vehicle has a compensating vessel 10, having a fluid-transporting coupling section within the housing of transformer. In the compensating vessel, a compensating plate 18 can move along an adjusting axis 16 under the influence of an accumulator and is engaged with the transforming oil, held by the compensating plate 18. A guiding apparatus for controlling the operation of the compensating plate has a couple of covered sections 30, 32 which is slidable in reverse. One covered section 32 is coupled with the compensating plate. The other compensating plate 30 is coupled with a non-moving section of the compensating vessel. At least one covered section operates, in cooperation with the rotation stop surface 34 of the compensating plate of the vessel. The compensating device may be arranged at the section under the floor of a railway vehicle. Even under a large lateral force, the compensating device can offer a fluid coupling section, which operates continuously between the compensating vessel and the housing of a transformer.

摘要： The disclosure relates to an hydraulic accumulator, in particular a diaphragm accumulator, having an accumulator housing and a separating element disposed therein, which separates two media spaces from each other, wherein a weld seam is formed by a laser or electron beam welding process without any filler materials, in that at least a part of the wall parts delimiting the transition point are melted to form the weld seam, which closes off the transition point towards the surroundings, in a manner that is free of protrusions with respect to an outer circumferential surface of a connection element.

摘要： Separator and hydraulic accumulator having such a separator. A separator, in particular for a hydraulic accumulator, such as a bellows accumulator, which is produced by a 3D printing process, consisting of one single diaphragm, which, when viewed in cross section, is deflected in an arcuate shape to form a multitude of bellows pleats at deflection points, which delimit the bellows pleats on the outside and the inside, and in that, to obtain an isotensoid or essentially isotensoid stress profile in the diaphragm, the notional extensions of the diaphragm surfaces adjacent to each deflection point form an acute angle with each other, at least in an initial state.

摘要： 2. A hydraulic accumulator, in particular a piston accumulator, comprising a separation element (16) which is movably arranged in an accumulator housing (10) and which separates two media chambers (24, 26) from each other, and comprising a distance measuring device for monitoring the position of the separation element (16), is characterized in that the distance measuring device is in the form of a radar device (32) that includes a transmitter (42) emitting a primary signal which upon at least partial reflection off the separation element (16), generates a secondary signal which, upon reception by a receiver (46), allows a position of the separation element (16) in the accumulator housing (10) to be determined.

摘要： A hydraulic accumulator, in particular in the form of a piston accumulator, has an accumulator housing (10) and a separating element (20) arranged in the housing. The separating element is in the form of a piston, which separates a fluid side (22) from a gas side (24). At least the gas side (24) can be inspected, at least in part, by at least one sight glass (34, 36) that is fixed in the accumulator housing (10).

摘要： A bellows accumulator has at least one accumulator housing (2) and a separating bellows (20) movably arranged in the accumulator housing (2). The separating bellows 20 has a plurality of bellows folds and separates two media spaces (8, 22) from one another. The stationary open end of the separating bellows (20) is fixed to the accumulator housing (2) by a securing device (24). The separating bellows (20) has, at its movable other end, a closure part (36) having a guide device (40) by which the closure part (36) is guided in the accumulator housing (2). The closure part (36) has, in addition to the guide device (40), a sealing device (50). At least in the one extended end position of the separating bellows (20), the sealing device (50) separates a fluid space (8), in which the bellows folds are arranged in the accumulator housing (2), from a fluid port (12) in the accumulator housing (2). At least in some of the other working positions, the sealing device (50) releases this fluid connection.

摘要： An equalization device is, in particular, in the form of a tank. The housing (2) of the tank has at least one inlet (8) and one outlet (10) for receiving and discharging fluid, respectively, at least in one of the housing walls (4) of the housing, which housing can be filled with the fluid. At least one equalization body (14) is arranged within the housing (2). The equalization body is at least partly provided with an elastically compliant separating wall (20). The interior of the equalization body is delimited, and is at least partly in pressure-equalizing connection (32) with the surroundings at a passage (12, 32) through one of the housing walls (4).
