Definitions

  • the displacer piston rod 8 is rigidly connected to the cooling member 4 which in turn adjoins the displacer piston head, as discussed above.
  • the displacer piston rod passes through a central opening 9 in the working piston 3, the central opening 9 in the working piston 3 being sealed by a resilient gasket.
  • the displacer piston rod 8 and working piston rod 10 are connected to a common drive means (not shown).
  • the displacer piston head heat exchanger 5 can be effectively cooled 'by coolant which is introduced into the cooling member 4 by Way of the hollow diseplacer piston rod 8.
  • the apparatus here described is a relatively simple means for facilitating efiicient operation of a hot air motor or pump demonstration model.
