    • An apparatus having a self-aspirating pump, with which, in a traction control mode, pressure fluid can be aspirated through an intake line from a pressure fluid supply tank of a master brake cylinder. Located in the intake line is a control valve that assumes its preferred blocking positoin and can then be switched into its open position by a pressure pulse generated by the pump, through a control line. This open position can be switched whenever a control valve, located in the brake line of the master brake cylinder, is switched by an electronic control unit of the control apparatus out of its preferred position thereby connecting the master brake cylinder to the wheel brake cylinders into another position, thereby carrying pump pressure to the control valve. Aspiration of pressure fluid from the supply tank is thus avoided upon pump startup with undesirable feeding. This prevents the production of noise from the pumping of pressure fluids into the master brake cylinder.
    • 一种具有自吸泵的装置,在牵引力控制模式下,压力流体可以通过来自主制动缸的压力流体供应罐的进气管线吸入。 位于进气管路中的是控制阀,其采用其优选的阻塞定位,然后可以通过由泵产生的压力脉冲通过控制管线切换到其打开位置。 只要位于主制动缸的制动管路中的控制阀通过控制装置的电子控制单元从其优选位置切换,则可以切换该打开位置,从而将主制动缸与车轮制动缸连接成 另一位置,从而将泵压力运送到控制阀。 因此,泵启动时避免了供应罐的压力流体的吸入,而不希望的进料。 这防止了压力流体进入主制动缸的噪音产生。

    • The invention seeks to reduce structure-borne sound emissions of the reciprocating piston pump. The reciprocating pump is includes an outlet valve, which has a valve seat and a valve closing body that is received in a hollow space and is loaded by a closing spring. One outlet bore radially originates at the circumferential region of the valve seat and branches off from the hollow space. The opening of the outlet bore toward the hollow space extends at least approximately between the valve seat and the end toward the closing spring of the gap of least cross section, which is formed between the valve closing body and the inside circumference of the hollow space. As a result, a slowed opening motion of the valve closing element is attained, in which opening motion an opening gap opens up that has its largest flow cross section in the region of the outlet bore. The supply flow, which increases slowly as the outlet valve opens, results in a slowed force variation speed in the drive train of the reciprocating piston pump and a reduced emission of structure-borne sound. The pressure fluid pumping device may be used for instance in hydraulic motor vehicle brake systems having an anti-skid system and/or traction control system.
    • 本发明旨在减少往复式活塞泵的结构传播声发射。 往复泵包括出口阀,其具有阀座和闭合阀体,所述阀座和阀关闭体容纳在中空空间中并且由闭合弹簧加载。 一个出口孔径向起始于阀座的圆周区域并从中空空间分支出。 出口孔朝向中空空间的开口至少大致在阀座与靠近中空空间的内圆周之间形成的最小截面的间隙的关闭弹簧的端部之间延伸。 结果,实现了阀关闭元件的缓慢的开启运动,其中打开运动开口间隙在出口孔区域中具有最大的流动横截面。 随着出口阀打开,供应流量缓慢增加,导致往复式活塞泵的传动系中的减速力变化速度减小,结构声音的排放减少。 压力流体泵送装置可以用于例如具有防滑系统和/或牵引力控制系统的液压机动车辆制动系统中。
