摘要： A ball cock for fluids carrying abrasive materials has its inlet passage terminating with a smaller cross section than the mouth of a ball passage which, in turn, has a smaller cross section than the mouth of the outlet passage aligned therewith. The cross sectional differences exceed manufacturing and assembly tolerances and have been found to minimize wear of the ball cock.
摘要翻译：承载研磨材料的流体的球阀具有其入口通道终止于比球通道的嘴部更小的横截面，该球形通道的横截面与通过其对准的出口通道的嘴部相比更小。截面差异超过制造和组装公差，并且已经发现可以使球阀的磨损最小化。

摘要： A flow-setting valve has a housing, a flow-guiding duct, a ceramic valve ball and a flow-regulating spindle. The flow-regulating spindle has a plurality of form-fitting elements fitting in complementary receptacles of the valve ball. At least the valve ball is made of an engineering ceramic material. The form-fitting elements are located in the vicinity of the outer edge of a disk which is connected with the flow-regulating spindle. The diameter of the disk is approximately half the diameter of the valve ball.

摘要： The ball valve, especially for a solvent-containing flow and/or an abrasive solid mixture, has a housing, a sintered ceramic valve seat, a sintered ceramic valve ball and an operating shaft for the valve ball guided through a shaft seal in the housing. The valve ball is positioned free of an elastic seal between seating surfaces of the valve seat and the valve seat has at least two sintered ceramic seat rings which are mounted in the housing and which are acted on with a pressing force by an elastic element supported in the housing. The valve ball is positioned between the seat rings which seal on the housing and are acted on with a sealing force. The seat rings have a plurality of seating surfaces which are formed like the surface of an inner core and contact tangentially on the valve ball along circumferential sealing lines. The elastic element providing the pressing force can be a compressible spring but it can also be a compressible medium fed to a compression chamber positioned adjacent at least one seat ring.

摘要： The digging tool for loosening and loading comprises an adapter attached to a tool support and a tooth attachable to the adapter. The tooth has a tooth bottom portion and a tooth peak which are independent separate components. The tooth peak has a supporting face and is mounted with that supporting face on a complementary supporting surface of the bottom portion of the tooth. The tooth peak has a mounting pin which is guided through a hole surrounded by the supporting surface of the bottom portion and is deformed into a rivet attaching the tooth peak and the tooth bottom portion.

摘要： A throttle device, especially a throttle valve, is a throttle cage which is a composite of at least two or three layers including an engineering ceramic layer and at least one metal sleeve. In a two-layer embodiment the ceramic is provided on the upstream side and the metal sleeve on the downstream side. In a three-layer configuration the ceramic layer is sandwiched between metal sleeves. The throttle device is particularly adapted to take up shock stresses and alternating stresses namely temperature and or pressure stresses, and also provides the requisite resistance to corrosion, abrasive action, cavitation and the like to materially increase the useful life of the throttle body.
