    摘要： A speed control device for limiting the idle and operating speed of a pneumatic power tool driven by an air turbine (20) and comprising an inlet passage (16) for supplying pressure air at a pressure (P1), one or more nozzles (25) for directing supplied motive pressure air onto the turbine wheel (22) of the air turbine (20), and a speed governor (21) with a movable valve element (43) biased by a turbine speed responsive control pressure (P3) and arranged to control the flow of supplied pressure air from the pressure air inlet passage (16) to the nozzles (25), wherein a pressure regulator (60) controlled by the pressure air supply pressure (P1) is arranged to adjust the control pressure (P3) by adjusting the size of a bleed passage (66) communicating with the atmosphere in response to the actual level of the pressure air supply pressure (P1) such that a decreasing pressure air supply pressure (P1) results in an decreased area of the bleed passage (66) and a following increased control pressure which results in an increased pressure air flow to the turbine nozzles (25) and a compensation for occurring variations in the pressure air supply pressure (P1).

    摘要： An improved pneumatic ADE-machine with a built-in logic has a clutch in the power transmission chain between a first drive gear and a second driven gear. The clutch includes two clutch parts (D, F), whereof a first part (D) is axially biased by a spring (C). Movable elements (E) are arranged between the clutch parts, which transfer the rotation from the first to the second clutch part, and an actuator (H) is arranged in connection with the first spring biased clutch part (D). When a feed force on a drill during drilling exceeds the biasing force of the spring, the movable elements displace the spring biased clutch part axially, which triggers the actuator (H) to send a corresponding signal to the machine logic.

    摘要翻译： 具有内置逻辑的改进的气动ADE机具有在第一驱动齿轮和第二从动齿轮之间的动力传递链中的离合器。 离合器包括两个离合器部分（D，F），其中第一部分（D）由弹簧（C）轴向偏置。 可移动元件（E）布置在离合器部件之间，该离合器部件将旋转从第一离合器部分传递到第二离合器部分，并且致动器（H）与第一弹簧偏置离合器部分（D）相连。 当在钻孔期间钻头上的进给力超过弹簧的偏压力时，可移动元件轴向移动弹簧偏置离合器部分，这触发致动器（H）向机器逻辑发送相应的信号。

    摘要： A drill spindle unit includes a housing, and a rotatable and longitudinally displaceable drill spindle provided with axial keyways for cooperation with internal projections of a drill spindle surrounding rotation drive sleeve, and a screw thread for cooperation with an internal thread of a drill spindle surrounding feed drive sleeve. Bearings for radial as well as axial support of the drill spindle relative to the housing are provided. The radial support bearings are arranged to transfer radial forces only, and a thrust bearing is arranged to transfer axial forces between the housing and the drill spindle. The thrust bearing is associated with an axial load sensing device by which signals are generated in response to the axial load applied on the drill spindle.
