The invention concerns a radial-piston engine of rotary type of the kind having a valve system comprising apertured disc rings arranged in intersliding relationship, one of said rings being stationary while the other one is arranged to take part in the rotary motion of the rotor. The valve opening relationship is determined by the manual angular positions of the discs. In accordance with the invention, filed injection takes place via an injection nozzle positioned in the stationary disc. The valve ring is formed with a through opening which in response to the position assumed my the rotor at the moment of fuel ignition forms an open communication means between the injection nozzle and the combustion chamber.

[ What is claimed:] [1.] A device in a rotary radial-piston engine comprising a stationary housing (2), a drive shaft (10) which is rotationally mounted substantially centrally inside said housing and which supports a hub (11) co-rotating therewith, at least two radially projecting cylinders (14) wh
[ What is claimed:] [1.] A device in a rotary radial-piston engine comprising a stationary housing (2), a drive shaft (10) which is rotationally mounted substantially centrally inside said housing and which supports a hub (11) co-rotating therewith, at least two radially projecting cylinders (14) which are mounted on the hub (11) or rotation therewith, said cylinders (14) forming, together with the hub (11) and the drive shaft (10), a rotary unit which is rotatable relative to the stationary housing (2), and a combustion chamber (25) formed in said hub (11), said combustion chamber having valve-operated inlets/outlets (26) for intake and exhaustion, respectively, of a gas, taking part in the combustion, and of combusted exhaust gases, said inlets/outlet (26) to and from, respectively, each combustion chamber (25) being formed axially in a valve ring (28) which co-rotates with the hub (11) and which is substantially concentric therewith, said valve ring (28) sealingly abutting against a stationary port ring (30) which is substantially concentric with the valve ring and which is connected to the housing (2), said port ring (30) being formed with axial intake and exhaust ports (36, 37) communicating with inlet and outlet ducts (34, 35) and arranged, upon rotation of said rotary unit (10, 11, 14, 16) relative to the housing (2), to alternatingly assume a position in alignment with that inlet/outlet (26) in the valve ring (28) that pertains to the respective combustion chamber (25), said valve ring (28) bearing against said port ring (30), wherein an injection duct (60) extends through the port ring (30), one end of said duct being connected to an injection pump system (65) and the opposite end of said duct, which is positioned in said port ring, debouching, via an injection nozzle (62), hint the combustion chamber at a point in close proximity to the place where the combustion chamber, disposed in said rotor, is positioned upon ignition of the combustion gas, and in that said valve ring (28) has a through opening (26) which in said position of the rotor forms an open communication means between the injection nozzle (62) and the combustion chamber (25).
