Abstract: A compliance spring is disposed between the brake pedal and the primary piston of a master cylinder, preferably between the push rod and the primary piston of the master cylinder. Selection of the initial spring compression load of the compliance spring, its permitted spring compression travel and its spring constant, allow for both a simplified and fine adjustment of the brake pedal feel per a brake feel index.

Abstract: Our problem relates to a master cylinder with a U-shaped seal. Our goal is to avoid defective bleeding of hydraulic braking systems. The defects arise out of the fact that the vacuum causes the lips of the seal (21) to stick together and to stick against the wall (41). To achieve this, reliefs (42) will be created on one wall (44) of one lip (28) facing the other lip (27) and on the edge face (50) of this same lip. These reliefs will prevent the lips from sticking tightly to one another and to the wall facing the edge face of the lips. This lack of sticking will prevent a vacuum from being created between the two lips and between the edge face of the lips and the wall (41). As a result, the seal will be able to return to a position in which bleeding can be performed effectively.

Abstract: A liquid solar thermal collector generation system has a liquid unit, a solar vaporizer, a turbine generator, a cooling and condensing unit, and a main control unit. The solar vaporizer heats a liquid from the liquid unit and converts the liquid to steam as a rotating power resource. As such result, the turbine generator is driven and then generates an electric power source. The steam passing through the turbine generator is re-converted to the liquid through the cooling and condensing unit, so the liquid unit from the cooling and condensing unit is recycled by the liquid unit. Therefore, the gaseous coolant solar thermal collector generation system utilizes the solar power to heat the coolant and further drive the steam generator, so the stream solar thermal collector generation system effectively utilizes the nature resource to generate the electric power source.
