摘要： 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.
摘要翻译：我们的问题涉及具有U形密封件的主缸。我们的目标是避免液压制动系统出现缺陷。缺点是由真空引起密封件（21）的唇缘粘在一起并粘贴在壁（41）上的事实。为了实现这一点，将在面向另一个唇缘（27）的一个唇缘（28）的一个壁（44）上和在该相同的唇缘的边缘面（50）上形成浮雕（42）。这些浮雕将防止唇部彼此紧紧地粘贴在面对嘴唇边缘的墙壁上。这种缺乏粘附将防止在两个嘴唇之间和唇缘的边缘面与壁（41）之间产生真空。结果，密封件将能够返回到可以有效地进行渗血的位置。

摘要： The invention relates to a motor vehicle master cylinder (1). More specifically, the invention relates to a piston (4, 5) of the master cylinder which has a first indentation (24) and a second indentation (27), which indentations are formed upstream of a port (13, 14) of the piston. The first indentation and the second indentation delimit a space within which hydraulic brake fluid can be stored so that it can be tapped off by an auxiliary braking device of the E.S.P. type.

摘要： When an element of the electro-hydraulic brake circuit (1) is malfunctioning, a master cylinder (2) can brake the vehicle. A brake actuation simulator (8) is then disconnected from the master cylinder (2) by means of an O-ring gasket (22) after the gasket has been compressed between a groove (16) in a secondary piston (11) and a bore (24) in the master cylinder. In order to prevent the gasket from being extruded from the groove during brake release (or brake pedal release) resulting from sudden braking, the invention makes provision for a pressure relief duct (32) to be provided inside the secondary piston. Extra pressure can then be discharged during brake release (or brake pedal release) through the brake release duct (32) from the inside of the chamber (30) of the simulator towards the primary chamber (10) of the master cylinder.

摘要： A master cylinder having a body with a bore therein delimited by a piston into a work chamber and a supply chamber. The work chamber (16) is connected to wheel brakes, while the supply chamber is connected to a fluid supply, through a supply duct. The piston has a shank retained by a guide ring mounted in the bore and a head bears against a thrust ring in a rest position. A first end of the supply duct is connected to the fluid supply, while a end is connected to the supply chamber. A hydraulic damping arrangement that dampens movement of the piston toward the thrust ring and includes structure for shutting off the second end of the supply duct such that brake fluid flows at a reduced flow rate from the supply chamber to the supply duct through at least one exhaust duct.
