Abstract

Body 1 is heated by the combustion of gas at ring burner 14, which also preheats the incoming air. Cooled body 2 encloses the cold chamber. Displacer 4, which also operates as a heat exchanger is made of light weight construction and includes a magnetisable tube 8 so that it can be raised by electromagnet 6. Displacer 4 has a central bore 11 and heat insulating plates 10 so that it is hot at the top and cold at the bottom. With the working piston 3 in the T.D.C. position, magnet 6 is de- energised and displacer 4 is released, driving the working fluid into the hot chamber where it expands and forces down the piston and displacer. The piston 3 is returned by a buffer or the inertia of a crank system. The working piston may be coupled directly to linearly oscillating parts of a driven machine e.g. a compressor so that these parts will be substantially free of transverse forces. Where a crank drive is employed, control of the magnetic field moving the displacer may be by way of switches which are actuated by the drive, for example by cams on the crankshaft. <IMAGE>
