The invention relates to a brake pressure regulator (110, 110a, 110b, 110c, 106), comprising:-a relay valve (202) for controlling the supply of pressurized air from a primary source (II) to at least one brake actuator (112a, 112b); -a first valve subunit (204) configured to be electronically actuated, where the first valve subunit (204) is configured to receive a primary supply pressure from the primary source (II), the primary supply pressure being intended to control the relay valve (202); and a second valve unit (206) configured to receive at least a secondary control pressure from a secondary source ("BST") and to receive at least a portion of the primary control pressure from the primary source (II) and to transfer either the primary control pressure or the secondary control pressure to the relay valve (202), wherein the primary control pressure from the primary source (II) is disconnected when the primary control pressure is transmitted to the relay valve (202), and/or the secondary control pressure from the secondary source (BST) is disconnected when the primary control pressure is transmitted to the relay valve (202). According to the invention, the second valve unit (206) is a mechanically operable valve in the form of a pneumatic control valve (206D, 206A, 206B, 206C) having a valve housing (304), the valve housing (304) comprising:-a pressurized guide sleeve (304.4) providing a valve chamber (305), the pressurized guide sleeve being configured to axially guide a pressure pick-up piston or similar spool (320) suitable for its pneumatic actuation, in particular only for its pneumatic actuation; and-a coil housing (304.5) configured to provide a coil chamber (306) around the pressurized guide sleeve (304.4) wherein the valve chamber (305) is devoid of a spring (321) and the coil chamber (306) is devoid of a coil or similar solenoid (311) such that the valve cartridge (320) is only pneumatically actuatable, in particular wherein the valve cartridge (320) is only pneumatically actuatable. The valve element (320) is subjected to aerodynamic force only due to pneumatic pressure in the valve chamber (305).
本发明涉及一种制动压力调节器(110、110a、110b、110c、106),包括:‑继动阀(202),用于控制从初级源(II)到至少一个制动促动器(112a、112b)的加压空气供应;‑被构造成被电子促动的第一阀子单元(204),其中所述第一阀子单元(204)被构造成接收来自所述初级源(II)的初级供应压力,所述初级供应压力旨在控制所述继动阀(202);和‑第二阀单元(206),其被构造成至少从次级源(“BST”)接收次级控制压力和从所述初级源(II)接收至少一部分所述初级控制压力,并将所述初级控制压力或所述次级控制压力中的任一个传递至所述继动阀(202),其中当所述次级控制压力被传递到所述继动阀(202)时,来自所述初级源(II)的所述初级控制压力断开,和/或当所述初级控制压力被传递到所述继动阀(202)时,来自所述次级源(BST)的所述次级控制压力断开。根据本发明,所述第二阀单元(206)是具有阀壳体(304)的气动控制阀(206D、206A、206B、206C)形式的可机械操作阀,所述阀壳体(304)包括:‑提供阀室(305)的加压引导套筒(304.4),所述加压引导套筒被构造成轴向引导适于其气动促动特别是仅适于其气动促动的压力拾取活塞或类似阀芯(320);和‑线圈壳体(304.5),所述线圈壳体被构造成在所述加压引导套筒(304.4)周边提供线圈室(306),其中,所述阀室(305)没有弹簧(321)并且所述线圈室(306)没有线圈或类似的螺线管(311),使得所述阀芯(320)仅能够气动地促动,特别是其中,所述阀芯(320)仅由于所述阀室(305)中的气动压力而受到气动力。
