Patent number: 11390257Abstract: A vehicle braking system includes an assistance device having a vacuum pump driven by an engine for communicating vacuum to a chamber of the assistance device. A control valve is interposed along a fluid line between the pump and the chamber. The control valve is in its first operative condition, where the inlet side of the vacuum pump communicates with the chamber, when pressure within the chamber is above a predetermined value; and is in its second operative condition, where the inlet side of the vacuum pump communicates with the atmosphere, when pressure within the chamber is below a predetermined value. In this second condition the pump intakes air from and feeds air into the atmosphere, thereby reducing the energy consumption by the engine required for driving the pump during stages where, within the chamber, there is a vacuum sufficient for the regular operation of the braking system.Type: GrantFiled: March 12, 2020Date of Patent: July 19, 2022Inventors: Gianluca Marcolongo, Renato Badino, Michele Ieluzzi, Giovanni Gabiati, Stefano Lucà, Paolo Graziano

Patent number: 11383687Abstract: A brake master cylinder assembly with adjustable fluid reservoir. The invention prevents air from entering a motorcycle hydraulic brake line by adjusting the fluid reservoir to be level with the ground of motorcycle operation. The brake handle remains parallel with the relative position of the handlebar the assembly is fastened to. All motorcycle brake master cylinders have a fluid reservoir and hydraulic piston that are in a fixed position relative to the handle and handlebar. The invention has a reservoir assembly which may be adjusted to any angle to keep the fluid reservoir level while the motorcycle is upright; allowing the motorcycle to have a brake handle and corresponding handlebar at any angle desired. The adjustable hydraulic fluid reservoir assembly prevents air from entering the brake line by reducing exaggerated angles incorporated with handlebar positions. The overall brake performance is therefore extended, mitigating risks' and extending service life.Type: GrantFiled: June 1, 2020Date of Patent: July 12, 2022Inventor: Andrew James Perry
