Rotary motor

Abstract

A rotary motor (10;1 10) is described, comprising a stationary cylinder housing (12;1 12) having an internal mainly circular rotor (20;120) mounted on a drive shaft (14;1 14) and where the rotor (20;120) is equipped with a piston (16;1 16) and that provided about the rotor (20;120) is a circular working chamber (18;1 18) with an inlet (42;142) and an outlet (32;132) for supply and removal, respectively, of the relevant drive medium, where provided in front of the inlet (42; 142) of the working chamber (18;1 18) there is a passage valve (30; 130) arranged to allow passage of the piston (16;1 16) and to close the working chamber (18;1 18) after the piston (16;1 16) has passed. The inlet (42;142) in the cylinder housing (12;1 12) is connected to an external combustion chamber (40; 140) for introducing the drive medium to the working chamber (18;1 18), where the combustion chamber (40; 140) comprises means for increasing the compression pressure in the combustion chamber, as said means comprises a compression rod (50;150), or a piston, arranged to be pushed into the combustion chamber (40;140) to increase the compression pressure.
