A prechamber arrangement adaptable in the upper part (2) of a cylinder in a piston engine (1), the prechamber arrangement comprising a prechamber (17), a spring-loaded prechamber valve (19) provided with a piston surface (32) for feeding a mixture of combustion air and fuel into the prechamber (17), and ignition means (20) for igniting the mixture of combustion air and fuel in the prechamber (17), which prechamber valve (19) can be moved between an open and closed position and which is pressed toward the closed position by a spring (24). The prechamber arrangement (15) comprises a chamber (28) for pressure medium and a second chamber (27) for pressure medium in flow connection with the chamber (28), which is delimited by the piston surface (32) of the prechamber valve on which the pressure of the pressure medium acts to move the prechamber valve (19) toward the open position, and which second chamber (27) is delimited by the piston surface (31) of a movable second piston (29). |
