    • The invention relates to a spin pump for conveying a liquid polymer melt. To drive the conveying means enclosed in the pump housing, a drive shaft is provided, which extends through the pump housing in a bearing bore, and which comprises an external end for connecting to a drive. To seal the outward extending drive shaft, a cooling sleeve is employed which connects in a pressure tight fashion to the pump housing. The cooling sleeve surrounds the drive shaft with a narrow gap therebetween, and the outer surface of the cooling sleeve is cooled by a coolant for increasing the viscosity of the polymer melt which enters the gap between the drive shaft and the cooling sleeve. With an increased viscosity, the melt acts to seal the gap without interfering with the rotation of the drive shaft.
    • 本发明涉及一种用于输送液体聚合物熔体的旋转泵。 为了驱动封装在泵壳体中的输送装置,提供驱动轴,驱动轴在轴承孔中延伸穿过泵壳体,并且包括用于连接到驱动器的外部端部。 为了密封向外延伸的驱动轴,采用以压力紧密方式连接到泵壳体的冷却套筒。 冷却套筒围绕驱动轴,其间具有窄的间隙,并且冷却套筒的外表面被冷却剂冷却,以增加进入驱动轴和冷却套筒之间的间隙的聚合物熔体的粘度。 随着粘度的增加,熔体用于密封间隙而不干扰驱动轴的旋转。

    • A hydraulic assembly (1), particularly for an electrohydraulic valve control of an internal combustion engine, and a hydraulic valve (2) for forming such an assembly are provided. The assembly includes a hydraulic valve with a valve housing (4) and a valve carrier (3) with a valve receiver (5) in which the valve housing is received. The valve housing has a first circumferential groove (9) and a second circumferential groove (10), with the grooves (9 and 10) being defined respectively by groove walls (13, 15 and 14, 16) and extending on two sides of a hydraulic connection (6) which extends through a peripheral wall of the valve housing (4). A bead (11, 12) formed by a plastic deformation of material of the valve carrier being received in each of the two said grooves (9, 10), so that the groove walls and the beads not only fix the valve housing in the valve receiver by positive engagement but also cooperate with each other to hydraulically seal the valve housing. Outer groove walls of the circumferential grooves are oriented towards each other and extend parallel to each other and perpendicularly to the receiving direction of the valve housing.
    • 提供了一种液压组件(1),特别是用于内燃机的电液阀控制和用于形成这种组件的液压阀(2)。 该组件包括具有阀壳体(4)的液压阀和具有阀接收器(5)的阀托架(3),阀壳体接收在阀座中。 阀壳体具有第一周向凹槽(9)和第二周向凹槽(10),凹槽(9和10)分别由凹槽壁(13,15和14,16)限定并在 液压连接件(6),其延伸穿过阀壳体(4)的周壁。 通过阀载体的材料的塑性变形形成的胎圈(11,12)被容纳在两个所述槽(9,10)中的每一个中,使得槽壁和胎圈不仅将阀壳体固定在阀 接收器通过正接合而且彼此配合以液压地密封阀壳体。 圆周槽的外槽壁朝向彼此并且彼此平行且垂直于阀壳体的接收方向延伸。
