摘要： A device for controlling the brake pressure in a hydraulic brake system with the aid of a pressure-limiting valve that limits the brake pressure to a predefined threshold value, and to that end is driven by an electronic device in accordance with a valve characteristic curve. The setting accuracy can be improved considerably if an estimating unit for estimating the brake pressure, a sensor system for measuring the brake pressure, a unit for determining a pressure difference between the measured brake pressure and the estimated brake pressure, as well as a controller unit which drives the pressure-limiting valve as a function of the pressure difference are provided.

摘要： The invention relates to vehicle braking system pressure modulating valves of the kind in which, above a first threshold of master cylinder pressure, the brake pressure increases with increasing master cylinder pressure but at a reduced rate, this rate being increased when a second threshold of master cylinder pressure is reached.In the valve according to the invention a primary plunger and a secondary plunger are carried in separate bores in the valve housing, there being a lost motion connection between them. Primary spring determines the first threshold pressure and secondary spring determines the second threshold pressure.

摘要： The subject invention relates to a fluid pressure intensifier (32) for increasing the pressure of an incompressible fluid and comprises a fluid reservoir (112) supplying fluid to a cylinder housing (72). The housing (72) includes first inlet (88) and outlet (90) cylinders extending between opposite ends (74,76) of the housing (72) and slideably receiving first inlet (96) and outlet (100) pistons therein. Second inlet (92) and outlet (94) cylinders are spaced parallel to the first cylinders (88,90) and further extend between the housing ends (74,76) for slideably receiving second inlet (98) and outlet (102) pistons therein. The first pistons (96,100) are forced in unison axially through the housing (72) to increase the pressure of the hydraulic fluid in the first outlet cylinder (90). A fluid channel (156) allows passage of the fluid from the first outlet cylinder (90) to the second inlet cylinder (92) and thus forces the second pistons (98, 102) in unison in opposing directions through the housing (72) to further increase the pressure of the fluid in the second smaller outlet cylinder (94). The fluid is then expelled from the housing (72) through an outlet (151) to an actuating device.
摘要翻译：本发明涉及一种用于增加不可压缩流体的压力的流体压力增压器（32），并且包括将流体供应到气缸壳体（72）的流体储存器（112）。壳体（72）包括在壳体（72）的相对端（74,76）之间延伸并在其中可滑动地接收第一入口（96）和出口（100）活塞的第一入口（88）和出口（90）。第二入口（92）和出口（94）圆柱体平行于第一圆柱体（88,90）间隔开并进一步在壳体端部（74,76）之间延伸，用于可滑动地接纳第二入口（98）和出口（102）活塞。第一活塞（96,100）通过壳体（72）轴向被一致地加力，以增加第一出口汽缸（90）中的液压流体的压力。流体通道（156）允许流体从第一出口滚筒（90）通到第二入口圆筒（92），从而通过壳体（72）在相反的方向上一致地迫使第二活塞（98,102）至进一步增加第二较小出口气缸（94）中的流体的压力。然后，流体通过出口（151）从壳体（72）排出到致动装置。

摘要： A hydraulic system actuator including a lever and structure defining a fulcrum for the lever and a link attached to the lever for actuating a pressure cylinder. The fulcrum of the lever is shifted relative to the lever in response to changing pressure within the hydraulic system created by rotation of the lever. The movement of the fulcrum increases the mechanical advantage of the lever as it approaches the end of its travel. The actuator has particular adaptability to vehicular brake systems.
