The prechamber arrangement for a piston engine (1) comprises a prechamber (17), a prechamber valve (19), a first piston (23) arranged in a first chamber (27) and comprising a piston surface (31) delimiting the first chamber (27), the first piston (23) being connected to the prechamber valve (19) for moving the valve (19) in the opening direction of the valve (19) when hydraulic pressure is applied on the piston surface (31) of the first piston (23), and a second piston (29), comprising a piston surface (32) for pressurizing pressure medium and for applying the hydraulic pressure of the pressure medium on the piston surface (31) of the first piston (23). The prechamber arrangement is provided with a pressure releasing channel (34), which is configured to release pressure from the first chamber (27) when the second piston (29) is in a certain predetermined position for allowing closing of the prechamber valve (19). |
