Abstract:
The suspension comprises a damper and spring unit (10) with a damper (12), a spring (14) and an adjustment device (16) for adjusting the height of the vehicle from the ground. The adjustment device (26) is made as a hydraulic linear actuator and comprises a cylinder (28) and a plunger (30). The adjustment device (26) is interposed between the cylinder (16) of the damper (12) and the spring (14) to change in a controlled manner the linear position of the bottom end of the spring (14) relative to the cylinder (16) of the damper (12) along the axis (Z) of this latter. The adjustment device (26) further comprises a sleeve (38) which is firmly secured to the cylinder (16) of the damper (12) and on which the cylinder (28) of the adjustment device (26) is fitted. The adjustment device (26) further comprises anti-rotation means (48, 50) for preventing relative rotation of the sleeve (38) and of the plunger (30) of the adjustment device (26) about the axis (Z) of the cylinder (16) of the damper (12). These anti-rotation means (48, 50) are advantageously made as guide means adapted to allow the plunger (30) to slide relative to the sleeve (38) of the adjustment device (26) along the axis (Z) of the cylinder (16) of the damper (12).
Abstract:
The shock-absorber (10) comprises a pressure tube (12), an outer tube (20), an intermediate tube (22) fitted onto the pressure tube (12), a control valve (28) for controlling the flow of a damping fluid to/from the intermediate tube (22) and a sealed connection device (36) for sealed connection of the control valve (28) with the intermediate tube (22). According to the invention, the sealed, connection device (36) comprises a spacer body (40) axially interposed between the intermediate tube (22) and the control valve (28), a first front sealing member (48) in contact with a front face (44) of the control valve (28), and a second front sealing member (54) in contact with the outer cylindrical surface of the intermediate tube (22), in such a manner as to form a double front seal between the control valve (28) and the intermediate tube (22).
Abstract:
The invention relates to an apparatus for dispensing maps, comprising input means for entering a destination by a user and means for providing on the map for dispensing a representation of at least one route from the location of the apparatus to the destination, the apparatus being adapted to print on the map a line representing the route. The route is preferably represented by a line printed on the map. The input means are preferably adapted for interactive communication with the user.
Abstract:
The piston (10) comprises a first pair of passive flow-control valves (18, 20), namely a first compensation valve (18) and a first rebound valve (20), a second pair of passive flow- control valves (22, 24), namely a second compensation valve (22) and a second rebound valve (24), and a flow-dividing solenoid valve (14) shiftable between a first operating position, in which it allows the flow of a damping fluid between an upper chamber and a lower chamber of the shock-absorber both through the first pair of passive flow-control valves (18, 20) and through the second pair of passive flow-control valves (22, 24), and a second operating position, in which it allows the flow of the damping fluid between the upper chamber and the lower chamber of the shock-absorber only through the second pair of passive flow-control valves (22, 24). The solenoid valve (14) is normally open, i.e. it is normally kept in the first operating position.
Abstract:
In a damping-adjustable shock-absorber (10) comprising a pressure tube (12), an outer tube (20), an intermediate tube (22) and a flow-control active valve (28) for controlling the flow of a damping fluid to/from the intermediate tube (22), a flow-control passive valve (32) is interposed between the intermediate tube (22) and the active valve (28). The passive valve (32) comprises a valve body (34, 36) in fluid communication on the one side (64) with the intermediate tube (22) and on the other side (82) with the active valve (28), a movable member (48) slidable in a chamber (46) of the valve body (34, 36), a spring (54) acting on the movable member (48), and metering means (56, 64, 68, 72, 76) for metering the flow of the fluid from the intermediate tube (22) to the active valve (28) through the valve body (34, 36). The metering means (56, 64, 68, 72, 76) are configured in such a manner as to al¬ low to obtain a pressure-flow rate characteristic curve with a first ascending section and a second constant, or even descending, section.
