Abstract (en)
[origin: WO2007097674A1] A one-way air inlet valve (1) comprises an elongate housing (110) and a valve member (200) arranged to open at a positive differential pressure and close at a negative or zero differential pressure. The elongate member (110) comprises a valve surface (140) provided with openings (140) and arranged to cooperate with the valve member (200) such that the valve member (200) sealingly engages the valve surface (140) at zero or negative differential pressures, and disengages the valve surface (140) at positive differential pressures. The valve surface (140) is arranged with an angle of 30 to 80 degrees in relation to the horizontal plane.
