  • the part circular valve plate 8 includes two portions 8a and 8b respectively cooperating with the outlet conduits 5 and 6, and the respective inlet conduits and working cylinders.
  • valve plate 8 has two housing parts 11 and 12 which engage each other in the region 13 as indicated in FIG. 3.
  • the housing part 12 is fixedly connected with working cylinders 2 and 3 and has a guideway 14 in which valve plate 8 is mountedv for sliding movement.
  • a movable housing part 11 carries the outlet conduits 5 and 6, and the inlet conduits I, and has a plate portion closing the guideway 14 so that the valve plate 8 is guided between the two housing parts.
  • Hinge means 15 are provided for mounting housing part 11 for angular movement on housing part 12, as best seen in FIG. 3.
  • the housing part 11 with the forked piece 4 and the inlet conduits 1 can be shifted to the position indicated in broken lines on the left of FIG. 3 so that guideway I4 and valve plate 8 are accessible, and also the interior of housing part 11 and of forked piece can be checked.
  • the guideway 14 has a lining consisting of wear portions 16 and sealing portion 17 which alternate, and which are exchangeable.
  • a transverse bar connects the ends of the part circular valve plate 8, and is mounted on a journal 21 so that valve plate 8, 8a, 8b can be angularly displaced about the axis of journal 21.
  • Piston rods 23 are connected by links 25 to the ends of bar 19, and are operated by pistons in cylinders 24 pivotally connected at 26 to the working cylinders 2 and 3, respectively.
  • the valve plate 8 By operation of one of the cylinder and piston means 24, 23, the valve plate 8 can be shifted between first and second positions.
  • portion 8b closes one of the inlet conduits I, and establishes communication between the working cylinder 3 and outlet conduit 6 through an opening 10.
  • the housing parts 11 and 12 and the valve plate 8 have a substantially conical shape so that the valve plate 8 extends transverse to the inlet conduits and outlet conduits.
