摘要： A pneumatic vibrator is provided which operates without the use of bearings. The vibrator includes a generally cylindrically formed housing and a cylindrical shaped rotor contained within the housing. The housing includes an inlet for receiving pressurized fluid and an outlet for discharging the fluid. The rotor has a number of jets formed adjacent the periphery of the rotor and extending through the outer longitudinal surface thereof. The rotor also includes an axle member extending from the rotor and which engages a recess formed in an end of the housing. In operation, the inlet of the vibrator is connected to a source of pressurized air. At least a portion of one of the jets is aligned with the inlet to receive the pressurized air. The air discharged from the jet produces a thrust driving the rotor about the inner wall of the housing. As the rotor rolls in the housing, each jet in sequence is aligned with the inlet and receives pressurized air while the axle member moves adjacent the inner wall of the recess so that some portion of the outer longitudinal surface of the rotor remains in contact with a portion of the inner wall of the housing. The rotor thereby continues to roll against the inner wall of the housing and the impacting therebetween causes vibrations.

摘要： A vibrator is provided which includes a free rolling rotor contained in a housing having a nose end portion. The rotor has a number of pockets for receiving ball pistons. Each pocket communicates with a valve port. Pressurized fluid sequentially passes through each valve port to the pocket with which the particular valve port communicates. In the pocket accessed by the pressurized fluid, a fluid chamber is created. The ball piston prevents the escape of fluid outwardly of the rotor. The pressurized fluid, in each accessed fluid chamber, causes the rotor to roll in the housing. The rotor rolling around within the housing applies centrifugal forces to the inside wall of the housing to produce vibrations. The fluid escapes from the rotor using the same valve ports which deliver the pressurized fluid. In addition, an assembly is provided in the housing to prevent the separation of the nose end portion from the housing when the nose end portion becomes worn and tends to separate from the housing.
摘要翻译： 提供了一种振动器，其包括容纳在具有鼻端部的壳体中的自由滚动转子。 转子有多个用于接收球形活塞的口袋。 每个口袋与阀口连通。 加压流体依次通过每个阀口到特定阀口与之连通的口袋。 在由加压流体访问的口袋中，产生流体室。 球活塞防止流体向转子外部逸出。 在每个被访问的流体室中的加压流体使得转子在壳体中滚动。 在壳体内旋转的转子将离心力施加到壳体的内壁以产生振动。 流体使用与输送加压流体相同的阀口从转子逸出。 此外，在壳体中设置组件以防止当鼻端部分磨损时鼻尖端部与壳体分离，并且倾向于与壳体分离。
