摘要： The leakage flow of a pressurized medium in gap type seals is controlled by a suction device at the sealing location of the gap seal. The suction device comprises a jet pump. The jet pump is driven by the pressurized medium in the gap seal or by an externally supplied fluid medium.

摘要： The present differential pressure limiting valve is constructed with an axially movable valve body having hydrostatic bearings including bearing shafts, whereby the bearing shafts are connected to opposite sides of said valve body in axial alignment. Normally the valve body is biased against the valve seat by an adjustable closing spring acting on the bearing shaft or valve body opposite the valve seat to close the valve. In addition, the face end of the bearing shaft opposite the valve seat may be loaded by a pressure medium. The respective diameters of the bearings may differ. However, the effective cross-sections of the valve body are preferally equal on both sides of the valve seat. The present unidirectionally effective valves are especially suitable for use in a parallel circuit, wherein one valve is effective for pressure relief in one flow direction whereas the parallel valve is effective for pressure relief in the opposite flow direction, whereby pressure relief may be provided, for example, for both chambers of a dual acting piston drive cylinder arrangement.
摘要翻译：本差压限制阀由具有轴承轴的静压轴承的可轴向移动的阀体构成，由此轴承轴以轴向对准的方式连接到所述阀体的相对侧。通常，通过作用在与阀座相对的轴承轴或阀体上的可调节的关闭弹簧将阀体偏压到阀座上以关闭阀。此外，与阀座相对的轴承轴的端面可以由压力介质加载。各轴承的直径可能不同。然而，阀体的有效横截面在阀座的两侧优选相等。本单向有效的阀特别适用于并联电路，其中一个阀对于一个流动方向上的压力释放是有效的，而平行阀对于在相反的流动方向上的压力释放是有效的，由此可以提供压力释放，例如，对于双作用活塞驱动气缸装置的两个室。

摘要： The present mechanical chucking device especially for a testing apparatus, has a friction reducing layer interposed between the clamping members and a base plate and another friction reducing layer interposed between the base plate and securing elements for the clamping members, whereby said clamping members may slide within a given range along the base plate without having to release the securing elements holding said clamping members to the base plate. The clamping members are driven by a spindle movably held in a guide block on the base plate which allows an exact concentric clamping of the sample.
摘要翻译：本发明的特别用于测试装置的机械夹紧装置具有介于夹紧构件和基板之间的摩擦减小层和介于基板和用于夹紧构件的固定元件之间的另一摩擦减小层，由此所述夹紧构件可在内沿着基板的给定范围，而不必将保持所述夹紧构件的固定元件释放到基板。夹持构件由可移动地保持在基板上的引导块中的主轴驱动，允许准确地同心夹紧样品。
