- the solenoid In a rest position of the two elevator cars 15, 16, however, blocks the check valve 50, the hydraulic connection 42.
- the solenoid is designed fail-safe. Therefore, the solenoid 49 releases the check valve 50 only upon application of a switching current.
- the switching magnet 49 blocks the blocking valve 50.
- the switching magnet 49 is in operative contact with a restoring spring which resets the switching magnet 49 in a blocking direction of the blocking valve 50.
- a pump 48 is arranged in the hydraulic connection 42 between the working areas 29, 30, 39, 40 of the hydraulic adjusting elements 20, 21 and the hydraulic adjusting elements 32, 33.

- the pump 48 thus has two delivery directions. In certain loading cases of the first and the second elevator car 15, 16, the pump 48 can also be used as throttling element.
- the pump 48 is connected to a speed-controlled motor 47 via a drive shaft.
- the output by the motor 47 to the pump 48 torque for the adjustment of the first or the second elevator car 15, 16th depends largely on the acceleration of the elevator cars 15, 16 and the load in connection with the adjustment of the first or the second elevator car 15, 16 from.

- the hydraulic power of the second elevator car 16 and optionally a loading of the second elevator car 16 are correspondingly loaded on the hydraulic adjusting elements 32, 33.
- a pressure pl of the pressurized fluid in the working areas 29, 30 of the hydraulic adjusting elements 20, 21 is greater than a pressure p2 of the pressurized fluid in the working areas 39, 40 of the hydraulic adjusting elements 32, 33.
- the motor 47 must overcome a larger or smaller load depending on the direction of the pump 48. If pressurized fluid is conveyed into the adjusting unit 20, 21 with the higher pressure p 1, the motor has to produce a greater torque than if pressurized fluid is conveyed into the adjusting unit 32, 33 with the lower pressure p 2. With a larger loading difference between the first and the second elevator car 15, 16 with a correspondingly large pressure difference, the pump 48 can also be used as a throttling element to reduce the flow rate of the pressurized fluid from the working areas 29, 30 of the hydraulic adjusting elements 20, 21 into the working areas 39, 40 of the hydraulic adjusting elements 32, 33 to limit.
- the pistons 37, 38 of the hydraulic adjusting elements 32, 33 move in the adjustment direction 61. Since that from the work areas 29, 30 of the hydraulic adjusting elements 20, 21st displaced pressure fluid in the working areas 39, 40 of the hydraulic adjusting elements 32, 33 flows, a synchronous movement of the one hand, the hydraulic adjusting elements 20, 21 and on the other hand the hydraulic adjusting elements 32, 33 achieved in the adjustment direction 24 and 61 respectively. In this case, the hydraulic adjusting elements 20, 21 and the hydraulic adjusting elements 32, 33 are designed coordinated with each other. When lowering the second elevator car 16, the movement of the pistons 27, 28, 37, 38 or the flow direction of the pressure fluid reverses.
- the adjustment of the elevator cars 15, 16 is controlled by a control unit 46.
- the control unit 46 has information about a first position measuring unit 72, a second position measuring unit 73, at least one first load measuring unit 78, 79 and at least one second load measuring unit 80, 81.
- the first position measuring unit 72 and the first load measuring unit 78, 79 are assigned to the first elevator cabin 15
- the second position measuring unit 73 and the second load measuring unit 80, 81 are assigned to the second elevator car 16.
- the control unit 46 thus always knows the positions of the first and the second elevator car 15, 16 relative to the elevator car carrier 2 and knows Similarly, a momentary loading of the first and the second elevator car 15, 16.
- the control unit 46 communicates with an elevator controller and has information on which floor is approached next and which cabin distance 77 between the elevator cars 15, 16 is set for this floor.
- the control unit 46 gives the motor 47 a torque in order to set the cabin distance 77 between the elevator cars 15, 16 at a given load, in a timely manner.
- the control unit 46 has the current positions of the elevator cars 15, 16 during the adjustment and switches the motor 47 off when the predetermined cabin distance 77 is reached.
- the control unit 46 controls the switching magnet 49 to such an extent that the check valve 50 releases the hydraulic connection 42 during the adjustment of the cabin distance 77 and the hydraulic connection 42 blocks after reaching the predetermined Kabinenabstande s 77.
- the hydraulic connection 42 is supplied by an auxiliary pump 44 with additional pressurized fluid.
- the auxiliary pump 44 conveys pressurized fluid from an oil reservoir 45 into the hydraulic connection 42. This additional supply of pressurized fluid takes place to compensate for oil losses.
- the auxiliary pump 44 is controlled by the control unit 46. Normally, a subtraction of the position values of the first position measuring unit 72 and the second position measuring unit 73 with a synchronous counter-adjustment of the elevator cars 15, 16 is a constant value. As the oil loss progresses, this value varies within a certain range. The control unit 46 detects exceeding a predetermined critical variance of this value and instructs the auxiliary pump 44 to deliver pressurized fluid until the oil loss is compensated.
- the upper regions 25, 26 of the hydraulic adjusting elements 20, 21 and the upper regions 35, 36 of the hydraulic adjusting elements 32, 33 are connected via a hydraulic connection 52.
- 16 pressurized fluid flows from the upper regions 25, 26 of the adjusting elements 20, 21 in the upper regions 35, 36 of the adjusting elements 32, 33 and vice versa.
- the pistons 27, 28 reduce the volume of the upper regions 25, 26 of the adjusting elements 20, 21, the volume of the upper regions 35, 36 for a given stroke of the elevator cars 15, 16 and for the same diameter of the upper regions 25, 26, 35th , 36 bigger. Therefore, the hydraulic connection 52 is connected to a pressure accumulator 54.
- the pressure accumulator 54 temporarily stores excess pressurized fluid from the upper regions 35, 36. Flows the pressure fluid in the opposite direction of the pressure accumulator 54 is stored Druckfuid back to the hydraulic connection 52 from.
- an additional pressure accumulator 54 can be dispensed with if the diameters of the upper regions 25, 26 of the adjusting elements 20, 21 are designed to be correspondingly larger.
- the pressure accumulator 54 is preferably coupled to the hydraulic connection 52 via a throttle valve 53.
- the throttle valve 53 limits the flow rate of the pressure fluid in the pressure accumulator 54 and from the accumulator 54, so that in a shock-like stroke of the elevator cars 15, 16, such as when a catch of the elevator car carrier 2, in the upper regions 25, 26, 35, 36 always enough pressure fluid remains to achieve a sufficient damping of the shock-like stroke.
- the hydraulic connection 42 is preferably connected to a further pressure accumulator and a further throttle valve.
- an additional pressure accumulator together with throttle valve can alternatively be dispensed with if the diameters of the working areas 39, 40 of the adjusting elements 32, 33 are designed to be correspondingly larger.
- the first elevator car 15 has an exit level 75.
- the second elevator car 16 has an exit level 76.
- the exit levels 75, 76 may be determined, for example, by floors of the elevator cars 15, 16.
- a cabin distance 77 is determined. If the two elevator cars 15, 16 are each stopped relative to the elevator car carrier 2, which is the case in the switching positions 50 of the switching valve unit 43, then the cabin distance 77 remains constant even when the elevator car carrier 2 moves through the driving space 3. By adjusting the first elevator car 15 and the second elevator car 16, the cabin distance 77 can be varied.
- a floor space between the floors 4, 5 depends on the architectural features of the building or the like.
- the distance between two consecutive floors can vary within a building.
- partitions may be provided for receiving an air conditioner in the building partially.
- the floor distance with respect to a basement may be different to a floor distance of the upper floors.
- an entrance hall can specify a larger floor level.
- the elevator installation 1 advantageously makes it possible to adapt the booth spacing 77 to the storey distance of the floors 4, 5 to be approached.
- a variation of the booth spacing 77 can take place within the building. This increases the architectural freedom.
- the two elevator cars 15, 16 can in particular be moved toward or away from one another, there are several advantages.
- the elevator cars 15, 16 are moved toward each other and the cabin distance 77 is shortened. Since both elevator cars 15, 16 are adjusted, the cabin distance 77 changes with the sum of the speeds of the individual adjustment movements of the elevator cars. Cabins 15, 16. This applies correspondingly for an enlargement of the cabin distance 77, in which the first elevator car 15 is moved in the adjustment direction 24 and the second elevator car 16 is moved in the adjustment direction 61.
- a further advantage is that the possible change of the cabin distance 77, that is to say the difference between a maximum cabin distance 77 and a minimum cabin distance 77, is composed of the possible adjustment movements for the elevator cars 15, 16.
- the possible stroke for the hydraulic adjusting elements 20, 21 for the first elevator car 15 and the possible stroke for the hydraulic adjusting elements 32, 33 for the second elevator car 16 add up to the possible change of the cabin distance 77.
- the design requirements the hydraulic adjusting elements 20, 21, 32, 33 are reduced for several reasons. On the one hand occurring bending forces or the like in the now shorter interpretable piston and bushings of the adjusting elements in the event of bumps transversely to the driving directions 1 1, 12 are reduced.
- the structural stability of the adjusting elements is generally higher.
- an elevator installation 1 with an elevator car carrier 2 can be provided which accommodates two or more elevator cars 15, 16.
- different distances between floors 4, 5 can be compensated within the building.
- a main advantage of the invention is the hydraulic communication between the adjusting elements 20, 21 of the first elevator car 15 and the adjusting elements 32, 33 of the second elevator car 16.
- the weight of the first elevator car 15 balances the weight of the second elevator car 16 or the pressure difference between them pl and p2 kept small in the adjusting elements 20, 21, 32, 33.
- the pumping capacity of the pump 48 is also small. Accordingly, smaller and lighter pumps can be used. This leads to a further significant weight reduction of the moving mass of the elevator system and to energy savings during operation.
- the hydraulic adjusting elements 20, 21 of the first elevator car 15 in a further arrangement on the lower cross member 18 and the hydraulic adjusting elements 32, 33 of the second elevator car 16 on the central cross member 17 can be mounted.
- the hydraulic adjusting elements 20, 21 of the first elevator car 15 on the central cross member 17 and the hydraulic adjusting elements 32, 33 of the second elevator car 16 on the upper cross member 19 can be mounted.
- both the hydraulic adjusting elements 20, 21 of the first elevator car 15 and the hydraulic adjusting elements 32, 33 of the second elevator car 16 can be mounted on the central transverse carrier 17.
- the two first-mentioned further arrangements of the adjusting elements 20, 21 and 32, 33 are advantageously designed with regard to the volume of the working areas 29, 30 and 39, 40 as well as the upper areas 25, 26 and 35, 36.
- these volumes are largely the same, since the crosswise effect of reducing the volume of the piston 27, 28 and 37, 38 is eliminated. Therefore, in these arrangements accumulator 54 and throttle valve 53 in the hydraulic connections 42 and 52 are obsolete.
- hydraulic adjusting elements 20, 21, 32, 33 can be designed so that each elevator car 15, 16 has only one hydraulic adjusting element. This eliminates the connecting lines 31, 51, 41, 71st
