    SchUtzesPATENTANSPRÜCHE :    
1. Gleichlaufsteuerung für hydraulisch bewegte schwere Körper, wie   Wehrschützen,   Bühnenpodien u. dgL, mit jeweils zwei Hubzylindern oder Hubzylindergruppen unter Verwendung eines den Unterschied der Wege der Druckstempel der beiden Hubzylinder oder Hubzylindergruppen messenden Umlaufgetriebes und eines von diesem beeinflussten Regulierschiebers in den Druckflüssigkeitsleitungen der Hubzylinder, gekennzeichnet durch   hydraulische (in die Druckflüssigkeitsleitungen   eingebaute, beispielsweise ein Regulierschieber mit vier Steuerkanten oder ein Regulierschieber mit zwei Steuerkanten und ein Drehschieber) oder mechanische (auf den Regulierschieberantrieb wirkende, beispielsweise ein dem Umlaufgetriebe nachgeschaltetes elektromagnetisches Wendegetriebe) Schaltmittel,

   durch die bei Bewegungsumkehr der Druckstempel (2,3) die Drosselungscharakteristik der Steuerkanten des Regulierschiebers (22) für die zu bzw. von den Hubzylindern (5,7) fliessenden Flüssigkeitsströme umgekehrt wird.

    PROTECTIVE PATENT CLAIMS:
1. Synchronization control for hydraulically moved heavy bodies, such as riflemen, stage podiums, etc. dgL, each with two lifting cylinders or lifting cylinder groups using an epicyclic gear that measures the difference in the travel of the pressure ram of the two lifting cylinders or lifting cylinder groups and a regulating slide influenced by this in the hydraulic fluid lines of the lifting cylinder, characterized by hydraulic (built into the hydraulic fluid lines, for example a regulating slide with four Control edges or a regulating slide with two control edges and a rotary slide) or mechanical switching means (acting on the regulating slide drive, for example an electromagnetic reversing gear connected downstream of the epicyclic gear),

   by reversing the movement of the plunger (2,3), the throttling characteristic of the control edges of the regulating slide (22) for the liquid flows flowing to and from the lifting cylinders (5,7).

Claims

2. Synchronization control according to claim l, characterized in that there is a hydraulic switching means in the design of the regulating slide (22) with four control edges, with a hydraulic fluid line (32,33) being guided from each lifting cylinder to the regulating slide housing (23), which is in front The confluence in the regulating slide valve housing (23) forks, so that its flow can be controlled by two control edges of the regulating slide (22).

- 3. Synchronization control according to claim 1, characterized in that there is a hydraulic switching means in a rotary slide valve (46) which is in the edge of a regulating slide (22) with two control to the lifting cylinders (5, 7) leading pressure fluid lines (44, 32 or 45, 35) is switched on. <Desc / Clms Page number 3>

4. Synchronization control according to claim 1, characterized in that there is a mechanical switching means in an electromagnetic reversing gear connected downstream of the epicyclic gear (16-19), which reverses the movement of a regulating slide (22) with two control edges when the pressure ram (2, 3) is reversed.
