Mechanical energy e.g. torque, producing device, has driving bodies defined as hollow pieces and have valve which reduces volume of bodies in open position and increases volume of bodies in closed position

摘要

The device has driving bodies which are connected with one another, where each body changes its volume during reversal of motion direction so that the volume of body which moves in gravity direction is less than that of the body moving in opposite direction. The bodies are defined as hollow pieces and have a valve which reduces the volume of the bodies in open position and increases the volume of the bodies in closed position.
