Abstract: An adjusting screw (15) for a control lever device (1) for vehicles, wherein said adjusting screw (15) comprises a screw body (18) with a threaded shank (19) that can be screwed in a corresponding threaded hole (16) of the lever device (1) and a locking body (26) pivotally connected to the screw body (18). The locking body (26) comprises contact means (27) interacting with the screw body (28, 18) such as to counteract the rotation of the locking body (26) relative to the screw body (18) to a certain extent and anchoring means (29) engaging an anchoring seat (17) of the lever device (1) such as to prevent that the locking body (26) may rotate relative to the threaded hole (16) of the lever device (1). There are also provided means (25) for preventing that the locking body (26) may be displaced along the shank (19) of the screw body (18).

Abstract: A control device such as a handlebar-mounted brake includes a support structure containing a hydraulic piston, a lever pivotally connected to the support structure by a pin, and a transmission element for transmitting force from the lever to the piston during a normal actuation stroke of the lever. The lever may pivot outward substantially beyond its normal rest position. A torsion spring biases the lever in the actuation direction so that the lever and the transmission element are normally in contact. However, in the event of a fall, the lever can pivot outward from its normal rest position, out of contact with the transmission element. The hydraulic components are thereby protected from damage, as the pin and support structure bear the entire impact force applied to the lever.

Abstract: A control lever device (1) for vehicles, comprising: a support structure (2) with means (3.4, 4) for connecting the device (1) to a handlebar; a cylinder-piston unit (5, 6) connected to the support structure (2); a lever (7) being pivotally connected to the support structure (2) along an angular actuation stroke (A) extending from an angular rest position (R) of the lever (7) in a first direction of rotation and along an angular collapse stroke (C) extending from said angular rest position (R) in a second direction of rotation, opposite the first direction; a transmission portion (8) being associated to the device (1) such as to transmit an actuation movement from the lever (7) along the angular actuation stroke (A) to the cylinder-piston unit (5, 6); The transmission portion (8) is arranged relative to the lever (7) such that, when the lever (7) is in the angular collapse stroke (C), it is separated from the transmission portion (8).

Abstract: A master cylinder unit for vehicles comprises a cylinder body which houses a pressure chamber suitable for holding fluid which can be pressurized and a reservoir suitable for containing the fluid. The master cylinder unit is of the type with an attached reservoir connectible to the cylinder body by a fixing screw which is disposed inside the reservoir and comprises a portion of the fluid-bleeding circuit.
