Latest Patents

Pembleton's latest patents include a brake proportioning valve for a motor vehicle that is responsive to both the front and rear brakes. This innovative brake valve is designed to be interposed in the brake line between the master cylinder and the rear wheel brakes. It limits the fluid pressure at the rear brakes relative to the pressure at the front brakes during the application of master cylinder pressure. The purpose of this design is to balance the front and rear brakes according to their relative effectiveness. The valve features an inertia sensor that detects the rate of vehicle deceleration and adjusts the pressure ratio between the front and rear brakes accordingly. This mechanism compensates for the load carried by the vehicle, which affects the effectiveness of the brakes.

Another patent by Pembleton is also a brake valve for a motor vehicle brake system. Similar to his previous invention, this valve is interposed in the brake line and limits the increase in fluid pressure at the rear brakes relative to the front brakes. The inclusion of an inertia sensor allows for modulation of the pressure ratio based on vehicle deceleration, ensuring optimal brake performance.
