| description | Change over valve for monitoring a connection between a pressure- medium source, an accumulator and a reservoir has a reversing valve (7, Fig. 1, not shown) which is controllable by a pilot valve 9, the valve member 25 of the pilot valve 9 is constructed as a stepped piston, to which the pressure in the accumulator (5) is applied at 42 and to which the pressure in the reservoir connection is applied at 45 and in the central zone of the valve member are arranged two additional control pistons sections 27,28, on which are provided control edges 38,39 which co-operate with control edges 40,41 of a valve housing 23 to control a connection between the source at 44 and the control side of the reversing valve (7) connected at 43. When the accumulator pressure is high the piston is moved to full flow from 44 to 43 and connect 43 to tank via bores 36 and 35. |
