    • In a device (1) for supplying a pressurized medium from a fixed component (2) into a rotating component (3) with a radially aligned sealing gap (11) provided between the components and in which the fixed component (2) comprises two rings (12, 13), the ring (13) delimiting the sealing gap (11) being held in an axially movable arrangement and with at least one control pressure chamber (35) provided between the two rings (12, 13), the movable ring (13) has an intermediate pressure chamber (31) on its end surface (16) facing the sealing gap (11) with this intermediate pressure chamber (31) being permanently connected to the control pressure chamber (35) by means of ducts (36, 37) worked into the axially movable ring (13).This embodiment allows the width of the radial sealing gap (11) to be set automatically, thereby practically precluding metal-on-metal friction between the components (2, 3) in the area of the radial sealing gap whilst only small leakage oil losses have to be accepted.
    • 在用于将加压介质从固定部件(2)供应到旋转部件(3)中的装置(1)中,具有设置在部件之间的径向排列的密封间隙(11),并且固定部件(2)包括两个环 (12,13),限定密封间隙(11)的环(13)保持在可轴向移动的布置中,并且具有设置在两个环(12,13)之间的至少一个控制压力室(35),可动环 (13)在其端表面(16)上具有面向密封间隙(11)的中间压力室(31),该中间压力室(31)通过管道(36)永久地连接到控制压力室 ,37)加工成可轴向移动的环(13)。 该实施例允许径向密封间隙(11)的宽度被自动设定,从而实际上排除了径向密封间隙区域内的部件(2,3)之间的金属对金属摩擦,同时只有小的漏油损失 被接受

    • In a device (1) for supplying a pressurized medium from a fixed component (2) into a rotating component (3, 3'), with an axially aligned annular groove (14) and radially aligned sealing gaps (15, 16) provided between the two components, a circumferential pressure chamber (29, 30) is worked into each of the end surfaces (21, 22) which limit the radially aligned sealing gaps (15, 16), with radially aligned control slots (37, 38) connecting the pressure chambers (29, 30) to the annular groove (14). Furthermore, the end surfaces (21, 22) which are provided with pressure chambers (29, 30) are configured with equal areas.This embodiment prevents the two components (2, 3, 3') making contact under pressure and, instead, both components (2, 3, 3') level out in a central position. As a result, trouble free operation is assured over a long period.
    • 在用于将加压介质从固定部件(2)供应到旋转部件(3,3')中的装置(1)中,具有轴向对准的环形槽(14)和径向对准的密封间隙(15,16) 两个部件,周向压力室(29,30)被加工成每个端面(21,22),这些端面限制径向排列的密封间隙(15,16),径向对齐的控制槽(37,38)连接 所述压力室(29,30)到所述环形槽(14)。 此外,设置有压力室(29,30)的端面(21,22)被构造成具有相等的面积。 该实施例防止两个部件(2,3,3')在压力下接触,相反,两个部件(2,3,3')在中心位置平稳。 因此,长期保证无故障运行。

    • The device for transferring a pressure medium has a stationary outer component with first pressure medium channels and an inner, rotatably drivable component inside the stationary outer component radially spaced at a distance from the stationary outer component. The inner component has second pressure medium channels. The outer component is connected to the housing of a machine tool and the inner component is connected to the machine spindle. A first and a second intermediate member in the form of an annulus are provided. The first and second intermediate members are positioned fixedly in the space between the inner and the outer components for bridging the distance between them. The first intermediate member has at least one first connecting channel and the second intermediate member has at least one second connecting channel. The at least one first connecting channel connects one of the first pressure medium channels to one of the second pressure medium channels and the at least one second connecting channel connects one of the first pressure medium channels to one of the second pressure medium channels. The first and the second intermediate members are laterally supported at one of the components so as to each define two radially extending sealing gaps and are displaceable relative to the other of the components.
