Control unit for an electro-hydraulic roof support control arrangement

A control unit/hydraulic control mechanism comprising a control unit, a distributor plate (10), and a valve block (11), the control unit having a protective casing (12) defining first and second chambers, the first chamber (21) accommodating a plurality of electromagnetic valves (14), and the second chamber (22) constituting a lead-through chamber for leading electric cables to the electromagnetic valves, the second chamber being provided with a respective aperture (34) for each of the electric cables, each of the apertures being adapted for connection to a complementary member attached to the associated electric cable, whereby the electric cables are connectible to the control unit so as to resist tensile forces, and in such a manner that the interior of the second chamber is sealed with respect to the external atmosphere, wherein the protective casing of the control unit is mounted on one side of the distributor plate, and the valve block is mounted on the other side of the distributor plate, the protective casing further defining a third chamber (19), an electronic control box (13) disposed within the third chamber, the third chamber being open at one side of the protective casing, and the electronic control box being configured such that one surface thereof is substantially co-planar with the open side of the third chamber when the electronic control box is fully inserted into the third chamber.
