Abstract

The sleeve valve has an external annular actuating piston (6a), its front faces sealing against a stationery valve seats. The end section of the valve sleeve opposite to the pressure inlet (3a) carries additional sleeve (9), which slides externally and is displaceable against a back pressure spring (8). The additional sleeve has a cylindrical section 9a) of larger diameter. In the atrest position, the section engages a cylindrical part fastened to the associated valve seat.
