SPEED LIMITING DEVICE FOR A SLIDING DOOR
A speed limiting device for a sliding door is described which comprises: a tightly closed casing, internally provided with at least one hydraulic circuit for the circulation of a hydraulic fluid and arranged to be made integral with a panel of the sliding door; a motion transmission means, located outside the casing and arranged to engage with a corresponding transmission element placed on the sliding door frame; a gear unit, located inside the casing and in fluid communication with the hydraulic circuit, connected to the motion transmission means through at least one transmission shaft and driven in rotation by the motion transmission means to move the hydraulic fluid inside the hydraulic circuit. The gear unit consists of a speed increasing gearbox comprising three or more toothed wheels with a different number of teeth. The speed increasing gearbox comprises in cascade, starting from the transmission shaft, a first toothed wheel with a first number of teeth, a second toothed wheel with a second number of teeth, a third toothed wheel with a third number of teeth, and a fourth toothed wheel with a fourth number of teeth, wherein the fourth number of teeth is smaller than the first number of teeth.
