Definitions

  • the piston, piston rod and slide together are arranged to perform a reciprocating movement along the axial centre axis of the piston.
  • the piston valve is movable between an open position and a closed position relative to the piston.
  • An axial bore extending through the piston rod forms a communication opening between the piston valve and an actuator at the opposite portion of the piston rod relative to the piston valve.
  • the connection between the piston valve and actuator can be mechanical, for example.
  • the piston valve is provided with a guide portion extending into the through bore of the piston rod.
  • Figure 3 shows the same as Figure 2 , but here the active part of the actuator is in its lower inactive position
  • Figure 4 shows the same as Figure 3, but here the piston is shown as it is on its way up in its compression stroke, while at the same time the piston valve is about to close.
  • a piston rod 13 is fixedly connected to the piston 4 and extends in a known way through a stuffing box 14 arranged in the lower end portion of the cylinder 2.
  • an intermediate rod 20 is articulated with the slide 16 by means of a pin bolt 22, the pin bolt 22 also extending through a corresponding bearing bore 25 in the piston rod 13.
  • the piston valve 10 is restrictedly movable relative to the piston 4, as the piston valve is provided with a guide portion 26 projecting into the bore 24 and being movable between two corresponding shoulders 28 in the bore 24.
  • the inward- facing part 30 of the guide portion 26 forms an essentially sealing piston in the bore 24.
  • the piston rod 13 is provided with a plunger 32 movable in the bore 24. The plunger 32 is prevented from being moved out of the bore 24 by means of a shoulder 34 in the bore 24.
