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).

7. WO/2015/124833 METHOD AND ARRANGEMENT FOR MAINTAINING FLUID FLOW PRESSURE IN A SYSTEM AT A PRESET, ALMOST CONSTANT LEVELWO27.08.2015
F16K 17/04
PCT/FI2015/050096POHJOLA, Heikki AnteroPOHJOLA, Heikki Antero
This invention relates to a method and arrangement for maintaining fluid flow pressure in a system at a preset, almost constant level. One application is an impulse turbine´s nozzle valve (1), which automatically maintains the system pressure essentially constant so that it does not depend on occasional variation of the pumped inflow, resulting that also the jet from the nozzle remains constant and its kinetic energy optimal. The earlier known nozzles do not independently maintain system pressure when the inflow varies. The nozzle valve (1) comprises a cylindrical body (2) and an inlet channel (3) and the out flow is arranged through a nozzle channel (8) situated at the other end of the body (2). Inside the body (2) is a needle (4), conical head of which can oscillate in the channel (8). The needle (4) shaft is guided by a slide element (11). To the other end of the body (2) is joined a diaphragm pressure accumulator (6) so that the needle (4) shaft end is pressured against its valve disc (10) by means of a compression spring (5), one end of which is pressed against a widening (12) at the needle (4) shaft. In the body (2) is a channel (13) through which the flow can pass the slide element (11) and proceed through channel (9) below the disc (10). When the disc (10) is supported by the accumulator (6) body the needle (4) is at its lowest position and closes the outflow channel (8). When the inflow pressure increases the valve disc (10) and the needle (4) rise together and the channel (8) opens correspondingly, resulting that the flow pressure remains essentially constant.
