摘要： L'ensemble générateur est du type comportant une soupape de maintien de pression résiduelle (14, 114, 214, 314).
La soupape (14, 114, 214, 314) comprend un élément de fermeture (32, 132, 232, 332) sollicité par des moyens élastiques (42, 142, 242, 342) vers un siège (30, 130, 230, 330). Selon l'invention, elle comprend également des moyens provisoires de retenue (52, 152, 252, 352) contenant la force des moyens élastiques et sensibles à au moins la présence de liquide de freinage pour libérer les moyens élastiques (42, 142, 242, 342).
Application aux installations de freinage hydraulique pour véhicule automobiles.-

摘要： The device (1) for controlling the braking of vehicles, comprises:
a pumping device (2) comprising a body (3) wherein at least a seat (4) is formed having a supply port (5), connectable to a work fluid storage tank (S), and at least a first port (6) communicating with a first line (7) connectable to the braking system (F) of a vehicle, where inside the seat (4) is slidably housed a piston (8) adapted to define at least a first chamber (4a) communicating with the first port (6) and which is movable between an idle position, wherein the supply port (5) is communicating with the first chamber (4a), and at least a first braking position, wherein the supply port (5) is isolated from the first chamber (4a);
first valve means (11) located along the first line (7) to allow the flow of the work fluid towards the braking system (F) of the vehicle as a result of the achievement of a predefined pressure difference at its extremities;
at least a second line (12) for braking directly communicating with the first chamber (4a) and connectable to a user point (V);
where the seat (4) has a by-pass port (14) communicating by means of a by-pass line (15) with the first line (7) for braking, downstream of the first valve means (11), being provided a control element (16) connected to the piston (8) and adapted to put the by-pass port (14) in communication with the first chamber (4a) in the idle position, and to isolate the by-pass port (14) from the first chamber (4a) in the first braking position.摘要翻译： 用于控制车辆制动的装置（1）包括：泵送装置（2），其包括主体（3），其中形成有至少一个座（4），该座（4）具有供应端口（5），该供应端口可连接到工作流体存储器 （S），以及与可连接到车辆的制动系统（F）的第一管线（7）连通的至少第一端口（6），其中座椅（4）内部可滑动地容纳活塞（8） 以限定与所述第一端口（6）连通的至少第一腔室（4a），所述第一腔室（4a）能够在其中所述供应端口（5）与所述第一腔室（4a）连通的空闲位置和至少第一制动 位置，其中供应口（5）与第一腔室（4a）隔离; 第一阀装置（11）沿着第一管线（7）设置，以允许工作流体由于在其末端实现预定的压力差而朝向车辆的制动系统（F）流动; 至少第二线路（12），用于直接与所述第一室（4a）连通且可连接至用户点（V）的制动; 在所述第一阀装置（11）下游，所述阀座（4）具有借助旁路管线（15）与所述第一管路（7）连通的用于制动的旁路口（14），所述第一阀装置 控制元件16连接到活塞8并且适于在旁通位置中使旁路端口14与第一腔室4a连通并且将旁路端口14与旁路端口14隔离开来， 第一室（4a）处于第一制动位置。
