A device for the operation of a valve (5) to the combustion chamber (6) of a combustion engine, wherein the combustion engine comprises a cylinder, a piston (3) displacably arranged in the cylinder (2), and a combustion chamber (6) delimited by the cylinder (2) and the piston (3), and said valve (5), and wherein the device comprises a valve actuator (7) that comprises an actuator chamber (8), an actuator piston (9) displacably arranged in the latter and arranged to drive the valve (5), and a communication channel (11) through which a pressure fluid is conducted into the combustion chamber (8) for the driving of the actuator piston (9) and, thereby, the valve (5) in a direction in which the valve (5) is opened. The communication channel (11) extends from the combustion chamber (6) to the actuator chamber (8), and said pressure fluid comprises fluid pressurized by the pressure in the combustion chamber (6).
A method of operating a valve (5) to the combustion chamber (6) of a combustion engine, wherein said combustion engine comprises a cylinder (2), a piston (3) displacably arranged in the cylinder (2), a combustion chamber (6) delimited by said cylinder (2) and said piston (3), and said valve (5), and a valve actuator (7) that comprises an actuator piston (9) arranged to drive the valve (5) and provided in an actuator chamber (8), wherein a pressure fluid is conducted into the actuator chamber (8) for the driving of the actuator piston (9) and, thereby, the valve (5), characterized in that pressure fluid pressurized by the pressure in the combustion chamber (6) is conducted to the actuator chamber (8) for the driving of the actuator piston (9) in a direction in which the valve (5) is opened, in connection with the opening of the valve (5).
A device for the operation of a valve (5) to the combustion chamber (6) of a combustion engine, wherein the combustion engine comprises a cylinder (2), a piston (3) displacably arranged in the cylinder (2), and a combustion chamber (6) delimited by the cylinder (2) and the piston (3), and said valve (5), and wherein the device comprises a valve actuator (7) that comprises an actuator chamber (8), an actuator piston (9) displacably arranged in the actuator chamber and arranged to drive the valve (5), and a communication channel (11) through which a pressure fluid is conducted into the combustion chamber (8) for the driving of the actuator piston (9) and, thereby, the valve (5) in a direction in which the valve (5) is opened, characterized in that said communication channel (11) extends from the combustion chamber (6) to the actuator chamber (8), and in that said pressure fluid comprises fluid pressurized by the pressure in the combustion chamber (6).
