Definitions

  • the present invention relates to improvements to a pendulum piston machine according to EP-A-0 303 649 (state of the art according to Article (54 (3) EPC).
  • This machine has at least one pendulum piston fixed to a connecting rod, the edge of which is in a preferably curved cylinder running.
  • the sealing strips 14 are slidably mounted and directly connected to one another by compression springs 15.
  • These springs 15 are axially displaceably mounted in the longitudinal bores of the pendulum piston and cause the sealing strips 14 to bear continuously against the cylinder walls 4.
  • Shorter compression springs 16 are supported in the blind holes of the pendulum piston, which reach only approximately to the center of the piston, and are supported in the bottom thereof and serve to center the piston laterally within the cylinder walls 4 Spring detection and pre-tensioning ensure that the pendulum piston runs safely and with as little friction as possible, the center of which runs with increasing speed on movement curves between Fig. 1A to approximately Fig. 1B.
  • Two or more coil springs 15 and / or 16 can be arranged coaxially one inside the other, or can be replaced by other elastic means.
