摘要： An expansion anchor includes an expansion sleeve with a slot formed through the sleeve wall and extending for its axial length and an expansion body which is displaceably positionable through the slot for expanding the sleeve into contact with the wall of a hole formed to receive the sleeve. The slot is in parallel relation with the axis of the sleeve. The expanding body is a cylindrical pin which has a diameter greater than the dimension of the slot measured in the circumferential direction of the sleeve. An insert is secured within the sleeve and has a threaded bore into which a member can be secured and held within the expansion anchor.

摘要： For securing an expansion anchor formed of an anchor sleeve and an expansion element into a prepared hole in a receiving material, a conventional piston type explosive powder charge driven setting gun is adapted to hold individual anchors in a guide member mounted on the gun and then by means of a combined sleeve-like piston guide and piston mounted within the guide member to insert the anchor from the guide member into the prepared hole and to drive the expansion element into the anchor sleeve for firmly securing the anchor within the hole.

摘要： A hammer drill is arranged to rotate and also apply percussive force to a tool receptacle. The percussive force is transmitted from a shaft to a drive piston which, in turn, reciprocates a percussion piston which drives the tool receptacle. The hammer drill includes a housing and a bearing rotatably mounted in the housing. The shaft is rotatably mounted in the bearing and its axis extends perpendicularly of the axis of rotation of the bearing. The bearing supports a contact rim which is in meshed engagement with the shaft. The contact rim is displaceably into frictional contact with a brake member for holding the contact rim against rotation while the bearing rotates carrying with it the shaft. Due to its meshed engagement with the contact rim, the shaft rotates about its own axis causing the drive piston to reciprocate.
摘要翻译：锤钻被布置成旋转并且还将冲击力施加到工具容器。撞击力从轴传递到驱动活塞，驱动活塞又使驱动工具容器的冲击活塞往复运动。锤钻包括壳体和可旋转地安装在壳体中的轴承。轴可旋转地安装在轴承中，并且其轴线垂直于轴承的旋转轴线延伸。轴承支撑与轴啮合的接触边缘。接触边缘可移动地与制动构件摩擦接触，用于在轴承随轴旋转的同时保持接触边缘抵抗旋转。由于其与接触边缘的啮合接合，轴围绕其自身的轴线旋转，致使驱动活塞往复运动。

摘要： In a hammer drill, a drive piston is reciprocated by a motor, and, over a pneumatic buffer, the reciprocating motion is transmitted to a percussion piston. A throttle valve regulates the flow of a fuel mixture to the motor for controlling its operation. A membrane switch connected to and operated by the pressure conditions within the pneumatic buffer controls the throttle valve.

摘要： In a motor driven drilling or chipping device, a housing forms a sealed housing space containing a gear arrangement and an air cushion propulsion mechanism driven by the gear arrangement. The housing space is partially filled with lubricating oil. A pressure equalizing nozzle has a bore connecting the interior of the housing space to the ambient atmosphere outside the housing. The port at the end of the nozzle bore communicating with the housing space is enclosed by wall members forming a stilling chamber. The stilling chamber is in communication with the sealed housing space and is arranged so that regardless of the position of the drilling or chipping device, it is not flooded by the lubricating oil and the lubricating oil does not flow out of the stilling chamber through the nozzle bore.

摘要： A hammer drill has a cylinder within a housing with the cylinder forming a piston chamber. A drive piston is reciprocally mounted within the piston chamber and is displaced by a motor. A percussion piston is located within the piston chamber with an air cushion space located between the two pistons. As the drive piston reciprocates, it moves the percussion piston back and forth by way of the air cushion located between them. One of the pistons has a conduit open at one end to the air cushion space and at the other end to the exterior of the cylinder. A closure plug is located in the one end of the conduit and closes off air flow from the air cushion space into the conduit at regular operating temperatures. If the temperature in the air cushion space rises due to air leakage from the space, the closure plug melts and connects the conduit with the air space so that the reciprocation of the percussion piston stops before the pistons strike against one another and cause damage.
摘要翻译：锤钻在壳体内具有气缸，气缸形成活塞室。驱动活塞往复安装在活塞室内并由电动机驱动。冲击活塞位于活塞室内，气垫空间位于两个活塞之间。当驱动活塞往复运动时，它通过位于它们之间的气垫来回移动冲击活塞。其中一个活塞具有一端在气垫空间处的导管，另一端连接到气缸的外部。封闭塞位于导管的一端，并在常规工作温度下封闭从气垫空间流入导管的气流。如果气垫空间中的温度由于空气从空间中泄漏而升高，则封闭塞熔化并将导管与空气空间连接，使得冲击活塞的往复运动在活塞彼此撞击之前停止并造成损坏。

摘要： In an electropneumatic hammer including an exciter piston and a percussion piston reciprocally displaceable within the bore of a guide cylinder, a sleeve-like clamping member is secured in an axially stationary position within the bore of the guide cylinder with the percussion piston passing through the clamping member. If there is no tool in the hammer and under certain other operating conditions, an axially displaceable tubular member located within the bore and laterally enclosing the clamping member, presses the clamping member inwardly into gripping contact with the percussion piston.

摘要： A straddling dowel includes at least a pair of shell members each having a first contact surface and a second contact surface. The first contact surfaces are disposed in contact with one another and extend in parallel with the axis of the dowel and the second contact surfaces are disposed in contact with one another and extend helically relative to the axis of the dowel. The first and second contact surfaces extend for substantially the entire axial length of the shell members.
