Abstract

A hydraulic synchronizing circuit includes at least one master cylinder unit including a primary chamber, a secondary chamber, a piston and at least one piston rod, the piston having a primary effective surface and a secondary effective surface. The hydraulic synchronizing circuit further includes at least one slave cylinder unit including a primary chamber, a secondary chamber, a piston and at least one piston rod, the piston having a primary effective surface and a secondary effective surface. The master cylinder unit and the slave cylinder unit are arranged to be single-acting. The secondary effective surface of the master cylinder unit and the primary effective surface of the slave cylinder unit are substantially equal. A tank at least partially formed by the secondary chamber of the slave cylinder unit and containing a fluid is provided. A pump sucks the fluid from the tank. A first conduit operatively connects the tank to the primary chamber of the master cylinder unit via the pump. A second conduit operatively connects the secondary chamber of the master cylinder unit to the primary chamber of the salve cylinder unit.
