    • A barrier valve including an armature, longitudinally movable toward a pole core by excitation of an electrical winding. A prestressed compression spring in a longitudinal bore of the armature, as well as a support body, loaded by the compression spring, that is braced on a shoulder of the bore. The barrier valve furthermore has a tappet, which engages the support body and is movable relative to the armature and carries a closing body of a seat valve. When the winding is excited, the closing body is movable, overcoming the valve stroke, toward a valve seat of the seat valve. When the winding is excited, the closing body can be lifted from the valve seat by hydraulic forces acting on the closing body toward the valve seat, counter to the spring force of the compression spring in the armature. The stroke of the tappet relative to the armature engaging the pole core is limited to an amount less than the valve stroke. The barrier valve can be used in slip-controlled hydraulic brake systems and is distinguished by low noise when the pressure limiting function becomes operative.
    • 一种包括电枢的隔离阀,通过电绕组的激励可纵向移动到极芯。 电枢的纵向孔中的预应力压缩弹簧以及由压缩弹簧加载的支撑体,该支撑体被支撑在孔的肩部上。 阻挡阀还具有挺杆,该挺杆接合支撑体并且可相对于电枢移动并且承载座阀的闭合体。 当绕组被激励时,闭合体可以移动,克服阀行程朝向座阀的阀座。 当绕组被激励时,相对于电枢中的压缩弹簧的弹簧力,闭合体可以通过作用在闭合体上的液压力从阀座抬起到阀座。 挺杆相对于接合磁极铁芯的电枢的行程被限制为小于阀行程的量。 隔离阀可用于滑动控制的液压制动系统,并且当压力限制功能变得可操作时,隔离阀被低噪声区分。

    • A cylindrical die for a pellet mill for animal feedstuffs is releasably clamped to a rotatable die holder by means of a series of clamping segments disposed in a recess at the end face of the die holder. The recess has a radially outer conically diverging surface which cooperates with conically shaped outer surfaces on the segments to produce clamping of the radially inner faces of the segments on an end portion of the die.The clamping segments are urged into engagement by springs acting on rods connected to the segments and are disengagable by means of a series of hydraulic rams which can be actuated to oppose the force of the springs. The direction of the forces is chosen to be at an angle to the axis of the die holder so as to cause the clamping segments to follow the surface of the recess and to move radially away from the die during disengagement. The angle chosen is preferably the angle of divergence of the recess. In a modification centering segments are interdigitated with the clamping segments.
    • 用于动物饲料的颗粒磨机的圆柱形模具通过设置在模具座的端面处的凹部中的一系列夹紧片段可释放地夹紧到可旋转模具保持器。 凹部具有径向外侧的锥形发散表面,其与段上的锥形外表面配合,以在模具的端部上产生段的径向内表面的夹紧。 夹紧段通过作用在连接到段上的杆上的弹簧而被推动接合,并且可通过一系列可被致动以抵抗弹簧的力的液压柱塞脱离。 力的方向被选择为与模座保持器的轴线成一定角度,从而使得夹紧段跟随凹部的表面并且在分离期间径向移动离开模具。 所选择的角度优选为凹部的发散角。 在一个修改中,定心段与夹紧段交错。
