Latest Patents
Yardley's latest patents include improvements in hydraulic anti-skid braking systems for vehicles. One of his patents focuses on a hydraulic anti-skid braking system of the pump and de-boost type. In this system, the operation of the pump is initiated by an operating piston that cooperates with the plunger of the pump. A potential issue arises when fluid is trapped in a chamber between the piston and the plunger, which could cause accidental pump operation. Yardley addresses this by adapting the one-way valve to function as a pressure relief valve, establishing a return path to a reservoir when the plunger moves away from the piston.
Another patent details a hydraulic anti-skid braking system where the position of the de-boost piston is determined by a volume of fluid trapped in a space by a dump valve. This dump valve works with a restrictor that limits the rate of fluid release when the dump valve is open, particularly at pressures above a pre-set level. By decreasing the flow rate of the dump valve, the time period for each anti-skid cycle is reduced. This innovation allows the pump to avoid maximum pressurization from zero, conserving energy during the re-application mode. Additionally, the rate of fluid release at lower pressures can be increased, which is beneficial for vehicles on low-friction surfaces.
