Abstract: A master cylinder which has an unusual ability to limit space requirements, to be fitted in vehicles controllable by handlebars, comprises a cylinder body provided with a seat for housing a portion of the handlebar. A chamber for slidably housing a piston extends along an axis inside the cylinder body. A manual control lever which acts on the piston is mounted on the cylinder body for pivoting about its fulcrum in a plane. The axis along which the chamber for slidably housing the piston extends intersects the plane of pivoting of the control lever at a point.

Abstract: A caliper of a disc brake comprises a caliper body having a first half-body and a second half-body. The first half-body has a first hole and the second half-body has a second hole, coaxial with the first hole. The holes receive at least one connecting member suitable for firmly securing the first half-body to the second half-body and further provide an attachment seat capable of receiving an attachment member suitable for firmly securing said caliper body to the fork of a motorcycle.

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.

Abstract: A hydraulic pump for vehicles controllable by handlebars, having an unusually small space requirement, including a reservoir suitable for containing a working fluid having a free surface at the top, a pump body provided with a wall which delimits a cavity, and also freely conveying the fluid from the reservoir to the cavity of the pump body through an opening provided in the wall of the pump body. The opening is provided in a portion of the wall of the pump body at a distance from the top thereof, so that, during the operation of the pump, the free surface of the fluid contained in the reservoir is able to fall below the top without the fluid exposing the opening.

Abstract: A hydraulic pump unit (1), for a vehicle, that is unusually capable of precise and effective bleeding, comprises a reservoir (2) for the brake fluid, a master cylinder (3) in the said pump connected to the said reservoir, and a bleed circuit (15) connected at one end to the said master cylinder and fitted with a bleed nipple (19, 119, 219, 319, 419) that is normally closed in order to shut the said circuit off, and it is constructed in such a way that the said bleed circuit (15) is connected at the other end, downstream of the said bleed nipple (19, 119, 219, 319, 419), to the said reservoir (2).

Abstract: A bypass valve-delay valve assembly for an electric-hydraulic braking system of an electrically driven vehicle which includes a bypass valve section in which the hydraulic braking circuit ducts are obstructed by a solenoid operated valve activated by an electric signal generated by brake pedal depression, and a delay valve section in which the hydraulic fluid is obstructed by a delay valve arranged in a regulator piston whose maximum stroke equals the pressure corresponding to the maximum energy recovery performance generated by the electric drive motors' braking action. Pressure exceeding the maximum energy recovery performance of the drive motors causes the delay valve to open adding hydraulic braking to the electric drive motor braking.

Abstract: Braking system for electrically driven vehicles, equipped with electric motors on the four wheels, consisting of a combined electric-hydraulic system including at least one hydraulic circuit mated to at least one pressure transducer or sensor connected to control centers for the electric motors.

Abstract: An antiskid device for a brake system of a motorvehicle and the like, effective to prevent jamming of a wheel and at the same time ensure a braking action thereof which is consistently the equal of the best possible relatively to the road surface, comprises an on-off valve placed in a line conducting the braking fluid from a master cylinder to a braking cylinder of said system, a wheel deceleration sensor effective to generate a wheel skidding signal continuously, a surge chamber put into communication with said line downstream of said on-off valve a piston movable within said surge chamber, and a control means for said piston driven continuously by said wheel skidding signal.
