Abstract:
PCT No. PCT/NO96/00023 Sec. 371 Date Nov. 5, 1997 Sec. 102(e) Date Nov. 5, 1997 PCT Filed Feb. 1, 1996 PCT Pub. No. WO96/23996 PCT Pub. Date Aug. 8, 1996A pressure reduction valve for reducing the pressure in double-acting, closed hydraulic systems when they are not attended. The valve comprises a valve housing (1) with a boring (6), whose ends communicate with the respective circuits, and wherein there are provided two slide valves (21, 22), which are attempted to be forced away from each other by a spring device (39). Each slide valve (21, 22) has a seat (28, 29) for a valve body (31, 32) which is influenced by springs (37, 38) which are also arranged to move the slide valves (21, 22) towards each other. Between the valve bodies (31, 32) there extends slidably a rod (40), whose ends can influence the valve bodies, and whose length is adapted to the slide valves (21, 22) possible distances of movement, thus enabling it to bring the valve bodies alternately away from their seats when the slide valves are forced towards each other under the influence of the pressures in the respective hydraulic circuits.
