- 1 - TO ALL WHOM IT MAY CONCERN: BE IT KNOWN THAT I, KARL KRIEGER, a citizen of the German Federal Republic, of Domagkweg 66, 5600 Wuppertal 1, German Federal Republic, have invented a certain new and useful DOUBLE-PLATE CONTROL DEVICE of which the following is a specification:- ABSTRACT OF THE DISCLOSURE A control device serves to control the fluid flow to and from double-acting rams, especially the rams of mining machinery, the control device having various internal ducts which are defined between two plates connected together. One of the two plates (a duct plate) has a main face formed with channels, some of which radiate outwardly from a ring of bores, and two of which are 'T'-shaped and extend generally tangential to the ring of bores. The outer plate (a connecting plate) closes the channels to define ducts and has bores communicating with the various ducts. Control valve units are detachably connected to the connecting plate, the control valve units being arranged to be actuated to effect desired connections between the various ducts by way of the bores in the connecting plate.
