    摘要： A synchronising system (1) is described, in particular for trucks for transporting motor vehicles and trailers, comprising at least one first and one second hydraulic motors (M1, M2) arranged in series along an hydraulic feeding circuit (L) by which they are actuated, at least first detection means (R1) of a rotation speed of the first motor (Ml) and at least second detection means (R2) of a rotation speed of the second motor (M2), the detection means (R1, R2) cooperating with the control and managing means (C), to detect differences in rotation speed between the first motor (M1) and the second motor (M2), such hydraulic feeding circuit (L) comprising at least one first by-passing line (B1) of the first motor (M1) connected with the hydraulic feeding circuit (L) upstream of the first motor (Ml) by interposing first switching means between the first by-passing line (B1) and the hydraulic feeding circuit (L), and at least one second by-passing line (B2) of the second motor (M2) connected to the hydraulic feeding circuit (L) upstream of the second motor (M2) by interposing second switching means between the second by-passing line (B2) and the hydraulic feeding circuit (L), the first and second switching means being actuated by the control and managing means (C).

    摘要： For the synchronized supply of fluid to a number of consumers is used a device (1) comprising a number of, corresponding to the number of consumers, mutually sealed supply chambers (10-13). By arranging the supply chambers to that they concentrically surround each other a very compact construction is achieved, the length of which does not increase when the number of supply chambers is increased.

    摘要： A piston (302) is disclosed that includes a longitudinal passage (321) disposed between outlets on the opposing faces of the piston, and a radial passage (325) extending from a node with the longitudinal passage to an outlet on the annular wall between opposing piston seals. Check valves (331,333) are disposed in the longitudinal passage between the node and each of the piston faces, such that each of the check valves enables fluid flow from its inlet to the outlet on the annular wall, and block fluid flow from the outlet on the annular wall to the inlet. In the event of pistons in a fluid system becoming out of phase with each other, fluid may be admitted through the inlet of the longitudinal passage and the respective check valve and out a side wall outlet, thereby bypassing the piston to exit via the respective end port, until another, out-of-phase piston or pistons in the system also reach full extension or retraction, automatically returning all pistons in the system to be in phase with each other.

    摘要： Il s'agit d'une installation oléodynamique pour l'actionnement d'un pont pour l'élévation de véhicules, comprenant une pompe (1), qui aspire de l'huile en provenance d'un réservoir (2) pour la mise en mouvement de vérins d'élévation (3) au moyen d'une série de conduits et d'appareils de contrôle de l'écoulement. Il est prévu, entre la pompe (1) et les vérins d'élévation (3), une pluralité de vérins de synchronisation (4) qui assurent le synchronisme dans le mouvement des parties mobiles du pont élévateur (12).

    摘要： The electrohydraulic lifting device for motor vehicles includes a pair of support platforms (1), respectively a first support platform and a second support platform, which are horizontal and parallel to each other, and mounted on respective tie rods (2) respectively actuated by a main cylinder (P1) and by a secondary cylinder (P2) fed by the same main cylinder (P1), under the control of a hydraulic control unit (16). The hydraulic control unit (16) is equipped with a synchronisation device (17) including a synchronization valve (18) aimed at connecting a hydraulic media conduit (20), delivering hydraulic fluid to the said main cylinder (P1), with a recycling conduit (22) leading a suitable volume of hydraulic fluid from the same main cylinder (P1) to the secondary cylinder (P2), so that to compensate the inadequacy of the delivery of fluid to the secondary cylinder (P2), or alternatively aimed at deviating an exceeding part of the recycled fluid to a discharge, respectively at the starting and when the support platforms (1) are getting into alignment at the floor level.
