<p>Pressure generating device esp. for a double-acting piston of a thrust centrifuge has a rotor is fitted on a drum shaft and has connection bores. A control disc is supported rotatable in the centre of the rotor transverse to the centrifuge axis. The control disc has cylinder bores in which points reciprocate under centrifugal force and are connected via piston rods to a crank disc in the control disc. The control disc is connected to a control bearing via eccentric pins, a fork lever and a control rod. The cylinder bores are covered by valve plates, each of which has two transposed slits and there is a connection to the cylinder chambers of the working piston via the slits and the connection bores of the rotor.</p> |
