摘要

Improvements in the construction of devices for the inversion of the axial movement of the thrust bottoms in centrifuges, composed of a piston displaceable in axial direction, fixedly attached to the thrust bottom by means of a rod or the like and arranged in a pressure-resistant cylinder, as well as a four-way valve, at least, which is connected by means of conduits to a source of liquid under pressure and to a device for collecting liquid under pressure, and whose liquid transfer and admission line is alternately commuted to one or the other spaces of the liquid. Cylinder on both sides of the piston, characterized in that the four-way valve is an electromagnetically switchable valve, whose coils of the electromagnet are connected, if necessary through an amplifier, with emitters of connection pulses arranged in the region of the travel of a stroke indicator coupled to the pushing mechanism, and moving with it in its swinging path.
